Open redirect vulnerability in claroline/redirector.php in Claroline before 1.8.10 allows remote attackers to redirect users to arbitrary web sites and conduct phishing attacks via a URL in the url parameter.

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.
