Visual Studio Denial of Service Vulnerability

Weakness

The product attempts to access a file based on the filename, but it does not properly prevent that filename from identifying a link or shortcut that resolves to an unintended resource.

Affected Software

NameVendorStart VersionEnd Version
Visual_studio_2017Microsoft15.0 (including)15.9.52 (excluding)
Visual_studio_2019Microsoft16.0 (including)16.11.24 (excluding)

Visual_studio_2022Microsoft17.2 (including)17.2.13 (excluding)
Visual_studio_2022Microsoft17.4 (including)17.4.5 (excluding)

Potential Mitigations

  • Follow the principle of least privilege when assigning access rights to entities in a software system.
  • Denying access to a file can prevent an attacker from replacing that file with a link to a sensitive file. Ensure good compartmentalization in the system to provide protected areas that can be trusted.
