On BIG-IP versions 15.0.0-15.0.1, 14.1.0.2-14.1.2.2, 14.0.0.5-14.0.1, 13.1.1.5-13.1.3.1, 12.1.4.1-12.1.5, 11.6.4-11.6.5, and 11.5.9-11.5.10, the access controls implemented by scp.whitelist and scp.blacklist are not properly enforced for paths that are symlinks. This allows authenticated users with SCP access to overwrite certain configuration files that would otherwise be restricted.
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.
