CISA Known Exploited Vulnerabilities Directory

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.

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

Microsoft Internet Explorer contains a memory corruption vulnerability due to the way the Scripting Engine handles objects in memory. Successful exploitation could allow remote code execution in the context of the current user.

Microsoft Windows Installer contains a privilege escalation vulnerability when MSI packages process symbolic links, which allows attackers to bypass access restrictions to add or remove files.

Microsoft Exchange Server Validation Key fails to properly create unique keys at install time, allowing for remote code execution.

Microsoft Edge and Internet Explorer contain a memory corruption vulnerability that allows attackers to execute code in the context of the current user.

Microsoft Windows Adobe Font Manager Library contains an unspecified vulnerability when handling specially crafted multi-master fonts (Adobe Type 1 PostScript format) that allows for remote code execution for all systems except Windows 10. For systems running Windows 10, an attacker who successfully exploited the vulnerability could execute code in an AppContainer sandbox context with limited privileges and capabilities.

Microsoft Internet Explorer contains a memory corruption vulnerability due to how the Scripting Engine handles objects in memory, leading to remote code execution.

Microsoft Windows kernel contains an unspecified vulnerability when handling objects in memory that allows attackers to escalate privileges and execute code in kernel mode.

SolarWinds Orion API contains an authentication bypass vulnerability that could allow a remote attacker to execute API commands.
