CISA Known Exploited Vulnerabilities Directory

Microsoft Win32k contains a privilege escalation vulnerability when the Windows kernel-mode driver fails to properly handle objects in memory. Successful exploitation allows an attacker to execute code in kernel mode.

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.

Microsoft Windows DNS Servers fail to properly handle requests, allowing an attacker to perform remote code execution in the context of the Local System Account. The vulnerability is also known under the moniker of SIGRed.

Microsoft Internet Explorer contains a memory corruption vulnerability which can allow for remote code execution in the context of the current user.

Microsoft Windows contains a spoofing vulnerability when Windows incorrectly validates file signatures, allowing an attacker to bypass security features and load improperly signed files.

Microsoft's Netlogon Remote Protocol (MS-NRPC) contains a privilege escalation vulnerability when an attacker establishes a vulnerable Netlogon secure channel connection to a domain controller. An attacker who successfully exploits the vulnerability could run a specially crafted application on a device on the network. The vulnerability is also known under the moniker of Zerologon.

Microsoft Windows kernel contains an unspecified vulnerability that allows for privilege escalation.

Microsoft Exchange Server improperly validates cmdlet arguments which allow an attacker to perform remote code execution.

Microsoft Defender contains an unspecified vulnerability that allows for remote code execution.

Microsoft Windows Print Spooler contains an unspecified vulnerability that allows for remote code execution.
