CVE-2024-38081:
vulnerability analysis and mitigation
Overview
The CVE-2024-38081 is a security vulnerability affecting Microsoft's .NET, .NET Framework, and Visual Studio products. This elevation of privilege vulnerability was disclosed on July 9, 2024, impacting multiple versions of the affected software including .NET Framework versions 2.0 SP2 through 4.8.1, .NET 6.0, and Visual Studio 2022 versions (NVD, Microsoft Support).
Technical details
The vulnerability has been assigned a CVSS v3.1 base score of 7.3 (HIGH) with the vector string CVSS:3.1/AV:L/AC:L/PR:L/UI:R/S:U/C:H/I:H/A:H. The vulnerability is related to improper link resolution before file access (CWE-59). The security fix specifically addressed changes to the System.IO.Path.GetTempPath method return value, affecting how temporary paths are handled between SYSTEM and non-SYSTEM processes (Microsoft Support).
Impact
The vulnerability could allow an attacker to achieve elevation of privilege. When exploited, it affects how temporary paths are handled, particularly with different behaviors between SYSTEM and non-SYSTEM processes. For SYSTEM processes, it returns the path %WINDIR%\SystemTemp, which is inaccessible to non-SYSTEM processes (Microsoft Support).
Mitigation and workarounds
Microsoft has released security patches to address this vulnerability, including KB5041019 and KB5041023. While a temporary workaround exists by setting the environment variable COMPlusDisableGetTempPath2=true, Microsoft explicitly does not recommend this approach as it disables the security fix. The recommended solution is to install the appropriate security updates through Windows Update or Microsoft Update Catalog (Microsoft Q&A).
