CISA Known Exploited Vulnerabilities

Description:

Microsoft Windows Scripting Engine contains an unspecified vulnerability that allows for memory corruption.

Description:

Microsoft Windows CryptoAPI (Crypt32.dll) contains a spoofing vulnerability in the way it validates Elliptic Curve Cryptography (ECC) certificates. An attacker could exploit the vulnerability by using a spoofed code-signing certificate to sign a malicious executable, making it appear the file was from a trusted, legitimate source. A successful exploit could also allow the attacker to conduct man-in-the-middle attacks and decrypt confidential information on user connections to the affected software. The vulnerability is also known under the moniker of CurveBall.

Description:

Microsoft SharePoint fails to check the source markup of an application package. An attacker who successfully exploits the vulnerability could run remote code in the context of the SharePoint application pool and the SharePoint server farm account.

Description:

Microsoft .NET Framework contains an improper input validation vulnerability that allows for remote code execution.

Description:

Microsoft Win32k contains a privilege escalation vulnerability due to the component failing to properly handle objects in memory. Successful exploitation allows an attacker to run code in kernel mode.

Description:

Microsoft Exchange Server contains an unspecified vulnerability that allows for remote code execution. This vulnerability is part of the ProxyLogon exploit chain.

Description:

Microsoft .NET Framework, Microsoft SharePoint, and Visual Studio contain a remote code execution vulnerability when the software fails to check the source markup of XML file input. Successful exploitation allows an attacker to execute code in the context of the process responsible for deserialization of the XML content.

Description:

Microsoft Windows Common Log File System (CLFS) driver improperly handles objects in memory which can allow for privilege escalation.

Description:

Microsoft Office Object Linking & Embedding (OLE) dynamic link library (DLL) contains a side loading vulnerability due to it improperly validating input before loading libraries. Successful exploitation allows for remote code execution.

Description:

Microsoft Windows Error Reporting (WER) contains a privilege escalation vulnerability due to the way it handles files, allowing for code execution in kernel mode.

Description:

Microsoft Windows Common Log File System (CLFS) driver contains an unspecified vulnerability that allows for privilege escalation.

Description:

Microsoft Open Management Infrastructure (OMI) within Azure VM Management Extensions contains an unspecified vulnerability allowing privilege escalation.

Description:

Mozilla Firefox and Thunderbird contain a race condition vulnerability when running the nsDocShell destructor under certain conditions. The race condition creates a use-after-free vulnerability, causing unspecified impacts.

Description:

Mozilla Firefox and Thunderbird contain a race condition vulnerability when handling a ReadableStream under certain conditions. The race condition creates a use-after-free vulnerability, causing unspecified impacts.

Description:

Mozilla Firefox and Thunderbird contain a type confusion vulnerability due to incorrect alias information in the IonMonkey JIT compiler when setting array elements.
