The write_array_file function in utils/include.pl in GForge 4.5.14 updates configuration files by truncating them to zero length and then writing new data, which might allow attackers to bypass intended access restrictions or have unspecified other impact in opportunistic circumstances.

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.

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.
