CVE-2022-35589: Cross-site Scripting (XSS) - Generic in forkcms

A heap buffer overflow issue exists in Windows 11 and earlier versions. A malicious application may be able to execute arbitrary code with SYSTEM privileges.

**Windows sxssrv!BaseSrvActivationContextCacheDuplicateUnicodeString Heap Buffer Overflow**

    Windows: heap buffer overflow in sxssrv!BaseSrvActivationContextCacheDuplicateUnicodeString## SUMMARYA heap buffer overflow issue exists in Windows 11 and earlier versions. A malicious application may be able to execute arbitrary code with SYSTEM privileges.## VULNERABILITY DETAILS```__int64 __fastcall BaseSrvActivationContextCacheDuplicateUnicodeString(UNICODE_STRING *Dst, UNICODE_STRING *Src){  unsigned int Length; // ebx  SIZE_T NewMaxLength; // r8  WCHAR *Heap; // rax  __int64 Status; // rax  Length = Src->Length;  if ( (_WORD)Length )  {    NewMaxLength = (unsigned __int16)(Length + 2); // *** 1 ***    Dst->MaximumLength = NewMaxLength;    Heap = (WCHAR *)RtlAllocateHeap(NtCurrentPeb()->ProcessHeap, 0, NewMaxLength); // *** 2 ***    Dst->Buffer = Heap;    if ( Heap )    {      memcpy_0(Heap, Src->Buffer, Length); // *** 3 ***      Dst->Buffer[(unsigned __int64)Length >> 1] = 0;      Status = 0i64;      Dst->Length = Length;    }    else    {      return 0xC0000017i64;    }  }  else  {    *(_DWORD *)&Dst->Length = 0;    Status = 0i64;    Dst->Buffer = 0i64;  }  return Status;}```The function above attempts to reserve two extra bytes for a trailing null character. The new size gets truncated to a 16-bit value[1], so if the size of the source string is 0xfffe bytes, the function will try to allocate a 0-byte buffer[2] and copy 0xfffe bytes into it[3].The vulnerable function is reachable from the `BaseSrvSxsCreateActivationContextFromMessage` CSR routine. However, the default size of the CSR shared memory section is only 0x10000 bytes, and some of that space must be reserved for the capture buffer header, so by default it's impossible to pass a big enough `UNICODE_STRING` to CSRSS. Luckily, the size of the section is controlled entirely by the client process, and if an attacker can modify `ntdll!CsrpConnectToServer` early enough during process startup, they'll be able to pass strings of (virtually) any size.## VERSIONWindows 11 12H2 (OS Build 22000.593)Windows 10 12H2 (OS Build 19044.1586)## REPRODUCTION CASEThis (not very reliable) proof-of-concept creates a new process in a suspended state, attempts to find and replace 32-bit value 0x10000 inside `CsrpConnectToServer`, and resumes the process' main thread.

Windows sxssrv!BaseSrvActivationContextCacheDuplicateUnicodeString Heap Buffer Overflow

**Windows sxs!CNodeFactory::XMLParser\_Element\_doc\_assembly\_assemblyIdentity Heap Buffer Overflow**

    Windows: Heap buffer overflow in sxs!CNodeFactory::XMLParser_Element_doc_assembly_assemblyIdentity## SUMMARYA heap buffer overflow issue exists in Windows 11 and earlier versions. A malicious application may be able to execute arbitrary code with SYSTEM privileges.## VULNERABILITY DETAILSIn 2020, Project Zero reported a heap buffer overflow in application manifest parsing[1]. The `MaximumLength` field in one of the `UNICODE_STRING` parameters of the `BaseSrvSxsCreateActivationContextFromMessage` CSR routine wasn't properly validated, and was later used by `XMLParser_Element_doc_assembly_assemblyIdentity` as the maximum size of a `memcpy` destination buffer. The fix added an extra `CsrValidateMessageBuffer` call to `BaseSrvSxsCreateActivationContextFromMessage`.We've just discovered that `BaseSrvSxsCreateActivationContextFromMessage` is not the only CSR routine that can reach `XMLParser_Element_doc_assembly_assemblyIdentity`. An attacker can trigger the same buffer overflow via `BaseSrvSxsCreateProcess`.1. https://googleprojectzero.github.io/0days-in-the-wild/0day-RCAs/2020/CVE-2020-1027.html## VERSIONWindows 11 12H2 (OS Build 22000.593)Windows 10 12H2 (OS Build 19044.1586)## REPRODUCTION CASE1) Enable page heap verification for csrss.exe:```gflags /p /enable csrss.exe /full```2) Restart the machine.3) Compile and run:```#pragma comment(lib, "ntdll")#include <windows.h>#include <winternl.h>#include <cstdint>#include <cstdio>#include <string>typedef struct _SECTION_IMAGE_INFORMATION {  PVOID EntryPoint;

Researchers, organizations, and bug disclosure platforms can all make improvements to help protect user data

Researchers, organizations, and bug disclosure platforms can all make improvements to help protect user data

Bug bounty programs can be a useful part of a layered security approach, but stakeholders have been urged to maintain a tight grip on their data handling practices throughout the disclosure process to avoid creating a data leak of their own.

At Black Hat USA yesterday (August 11), delegates were told how research oversights and shoddy data governance principles across the bug bounty market have resulted in the leak of users’ personally identifiable information. And what’s more, this data is often still available long after the corresponding ticket has been closed.

In an interesting presentation, Dylan Ayrey, CEO of Truffle Security (the company behind TruffleHog), and Whitney Merrill, data protection officer and lead privacy counsel at software firm Asana, took a closer look at the potential pitfalls of the bug bounty disclosure process – starting with researchers.

Citing real-world examples, Ayrey said that while many bug bounty programs prohibit researchers from accessing user data, this does still happen. For instance, a blind cross-site scripting (XSS) exploit could trigger on an administrator endpoint, resulting in the dump of the entire user database.

Data gleaned from bug bounties can end up being stored in a wide range of systems

This user data could then be pushed to various third-party storage systems, along with being appended to the bug bounty program’s issue tracker – all of which then become a potential leak vector of their own.

Scaled up across the many hundreds of programs out there, this could result in a wealth of potentially sensitive data being stored in various places for an extended period.

**Leave no trace**

In addition to accidental research discoveries, Ayrey and Merrill said that organizations and bug bounty platforms are also opening the door to leaks through their failure to request that bug hunters delete all relevant data, or by simply leaving the sensitive information on file, long after the bug support ticket has been closed.

Offering advice to those who host bug bounty programs, Merrill said: “We’re probably not going to get to ‘perfect’, but we can take incremental steps to move forward. Basic data governance principles and data lifecycle best practises will help get you there.”

Ayrey added: “These privacy leaks in bug bounties are really common, and for every example that we can share publicly there are 100 examples that can’t be shared publicly. I think it’s time that we start a conversation about it and reduce some of the impact of this.

“We do believe that bug bounties are a positive force for change, and that companies that run bug bounties are in a better place than companies that don’t.”

CI/CD support is next for WAF security tool

CI/CD support is next for WAF security tool

Popular open source hacking tool GoTestWAF has become the first utility of its type to evaluate API security platforms, Black Hat USA attendees have learned.

Launched in April 2020, the security testing tool simulates OWASP and API exploits to test the detection capabilities of web application firewalls (WAFs), NGWAFs, RASPs, WAAPs, and, now, API security tools.

It supports REST, GraphQL, gRPC, WebSockets, SOAP, XMLRPC, and legacy APIs.

OpenAPI-based scanning has been introduced “so you can scan exactly what is defined in your API spec during the attack simulation”, Brandon Shope, principal security engineer at Wallarm, told attendees at his Arsenal session yesterday (August 11).

The GoTestWAF GitHub repo explains how OpenAPI (formerly Swagger) file scans work, which OpenAPI features are supported, and how “instead of constructing requests that are simple in structure and send them to the URL specified at startup, GoTestWAF creates valid requests based on the application’s API description in the OpenAPI 3.0 format”.

**More attack types incoming**

Other new features currently in development, meanwhile, are a daemon for CI/CD pipelines with API and server mode, and support for additional attack types, including Java, Python, and .NET serialization attacks, said Shope.

GoTestWAF generates malicious requests using encoded payloads placed in different parts of HTTP requests. The results indicate the number and percentage of path traversal, shell injection, cross-site scripting (XSS), and various other attack types blocked by the security tool.

GoTestWAF compares scan results to ModSec as a baseline, Shope said, and presents them in a “readable, nicely formatted PDF”. Wallarm CEO Ivan Novikov described this as a “really important” feature ahead of Shope’s presentation.

Testing for false negatives and positives is seen by Wallarm as invaluable given WAFs’ notoriety for generating false positives, which the API security firm says often occupies users at the expense of testing false negative rates.

**Community payloads**

Multiple ‘nested’ encoding support, codeless checks with YAML files, dockerization, and community payloads were also highlighted at the Las Vegas event.

Community support is a significant factor in the tool’s appeal, Novikov told The Daily Swig, citing community test cases documented by researchers from security intelligence search engine Vulners team “and then supported by others”.

GoTestWAF is already “used about 100 times a week” and asked about during sales and marketing calls by “about five enterprise companies a week”, according to Novikov.

Wallarm launched a free Online WAF tester for the tool last month.

The post Researchers found one-click exploits in Discord and Teams appeared first on Malwarebytes Labs.

A group of security researchers have discovered a series of vulnerabilities in Electron, the software underlying popular apps like Discord, Microsoft Teams, and many others, used by tens of millions of people all over the world.

Electron is a framework that allows developers to create desktop applications using the languages used to build websites: HTML5, CSS, and JavaScript. It's an open source project that has been used as the foundation for some extremely popular apps. Electron itself is built on the open source Chromium browser project (the basis of Google Chrome), and the NodeJS JavaScript runtime which is built on Chromium's V8 JavaScript engine—a significant source of Chrome security problems.

**Building blocks**

It is not uncommon for developers to use other projects, frameworks and libraries as building blocks for their projects. Building on proven code makes sense: It saves time, it is easier for others to get involved, and everyone benefits from all the layers of solved problems in the existing codebase.

The problem with building software on existing foundations, provided by others, is that its developer may not fully understand the security implications of certain decisions or configurations. And they need to rebuild their own application whenever a security vulnerability is fixed in the software they're building on top of, and then distribute that update to their users.

Probably the most famous example of such a building block vulnerability is Log4Shell. Log4Shell is a vulnerability that was found in Log4j, an open source logging library written in Java that was developed by the Apache Software Foundation. Millions of applications use it, and some of them are enormously popular—such as iCloud, Steam, and Minecraft—so the impact of the vulnerability was enormous.

The chances of applications harboring out-of-date underpinnings are software are high. And the reservoir of known bugs that are fixed in, say, Chrome, but not yet fixed in Electron, or fixed in Electron but not yet fixed an application built on top of Electron, is something that criminals and researchers can exploit.

A group of researchers recently presented research into Electron vulnerabilities at the Black Hat security conference having done exactly that. For a peek into what they did, and a look at how complicated modern bug hunting is, read researcher s1r1us's explanation of how they went about finding a remote code execution (RCE) vulnerability in Discord by chaining a new cross-site scripting vulnerability, a CSP bypass in Discord's out-of-date Chrome version, and an exploit for an existing V8 vulnerability.

In the case of s1r1us's Discord bug, what the researchers found could be exploited with nothing more than a malicious link to a video. With Microsoft Teams, the bug they found could be exploited by inviting a victim to a meeting. In both cases, if the targets clicked on these links, an attacker would have been able to take control of their computers.

**Mitigation**

The most general and best advice in many cases is to avoid clicking on links that come in unexpected or in unusual ways. In an ideal world you would distrust them with the same vigor as the links in your mailbox and on social media. However, this can be very difficult in practice because many of these applications _require_ you to click on links to join meetings, accept invitations and so on.

A more workable solution, suggested by the researcher, is to use apps like Discord or Spotify inside your browser, because then you have the protection afforded by Chrome, which is much larger than the one provided by Electron, and you have control whether it’s up to date or not.

Most of us though, will simply stick to downloading our security updates, and hoping the people who make the software are too.

Researchers found one-click exploits in Discord and Teams

Cisco on Wednesday released patches to contain multiple flaws in its software that could be abused to leak sensitive information on susceptible appliances.
The issue, assigned the identifier CVE-2022-20866 (CVSS score: 7.4), has been described as a "logic error" when handling RSA keys on devices running Cisco Adaptive Security Appliance (ASA) Software and Cisco Firepower Threat Defense (FTD)

Cisco on Wednesday released patches to contain multiple flaws in its software that could be abused to leak sensitive information on susceptible appliances.

The issue, assigned the identifier CVE-2022-20866 (CVSS score: 7.4), has been described as a "logic error" when handling RSA keys on devices running Cisco Adaptive Security Appliance (ASA) Software and Cisco Firepower Threat Defense (FTD) Software.

Successful exploitation of the flaw could allow an attacker to retrieve the RSA private key by means of a Lenstra side-channel attack against the targeted device.

"If an attacker obtains the RSA private key, they could use the key to impersonate a device that is running Cisco ASA Software or Cisco FTD Software or to decrypt the device traffic," Cisco warned in an advisory issued on August 10.

Cisco noted that the flaw impacts only Cisco ASA Software releases 9.16.1 and later and Cisco FTD Software releases 7.0.0 and later. Affected products are listed below -

*   ASA 5506-X with FirePOWER Services
*   ASA 5506H-X with FirePOWER Services
*   ASA 5506W-X with FirePOWER Services
*   ASA 5508-X with FirePOWER Services
*   ASA 5516-X with FirePOWER Services
*   Firepower 1000 Series Next-Generation Firewall
*   Firepower 2100 Series Security Appliances
*   Firepower 4100 Series Security Appliances
*   Firepower 9300 Series Security Appliances, and
*   Secure Firewall 3100

ASA software versions 9.16.3.19, 9.17.1.13, and 9.18.2, and FTD software releases 7.0.4, 7.1.0.2-2, and 7.2.0.1 have been released to address the security vulnerability.

Cisco credited Nadia Heninger and George Sullivan of the University of California San Diego and Jackson Sippe and Eric Wustrow of the University of Colorado Boulder for reporting the bug.

Also patched by Cisco is a client-side request smuggling flaw in the Clientless SSL VPN (WebVPN) component of Cisco Adaptive Security Appliance (ASA) Software that could enable an unauthenticated, remote attacker to conduct browser-based attacks, such as cross-site scripting, against the victim.

The company said the weakness, CVE-2022-20713 (CVSS score: 4.3), impact Cisco devices running a release of Cisco ASA Software earlier than release 9.17(1) and have the Clientless SSL VPN feature turned on.

While there are no workarounds to remediate the flaw, affected users can disable the Clientless SSL VPN feature, although Cisco warns doing so "may negatively impact the functionality or performance" of the network.

The development comes as cybersecurity firm Rapid7 disclosed details of 10 bugs found in ASA, Adaptive Security Device Manager (ASDM), and FirePOWER Services Software for ASA, seven of which have since been addressed by Cisco.

These include CVE-2022-20829 (CVSS score: 9.1), CVE-2022-20651 (CVSS score: 5.5), CVE-2021-1585 (CVSS score: 7.5), CVE-2022-20828 (CVSS score: 6.5), and three other flaws that have not been assigned a CVE identifier.
