The frontend rendering component in TYPO3 4.5.x before 4.5.39, 4.6.x through 6.2.x before 6.2.9, and 7.x before 7.0.2, when config.prefixLocalAnchors is set and using a homepage with links that only contain anchors, allows remote attackers to change URLs to arbitrary domains for those links via unknown vectors.

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.
