Exposure of Version-Control Repository to an Unauthorized Control Sphere

CWE-527

The product stores a CVS, git, or other source-control repository in a directory, archive, or other resource that is stored, transferred, or otherwise made accessible to unauthorized actors.

Version control repositories such as CVS or git store version-specific metadata and other details within subdirectories. If these subdirectories are stored on a web server or added to an archive, then these could be used by an attacker. This information may include usernames, filenames, path root, IP addresses, and detailed diff data about how files have been changed - which could reveal source code snippets that were never intended to be made public.

We track 2 vulnerabilities of this type. 100% are rated high or critical, and the average CVSS score is 8.3.

How this weakness is prevented

  • Operation Distribution System Configuration: Recommendations include removing any CVS directories and repositories from the production server, disabling the use of remote CVS repositories, and ensuring that the latest CVS patches and version updates have been performed.
