Name of the Vulnerable Software and Affected Versions Twonky Server versions 7.0.11 through 8.5

Description The issue allows remote attackers to share the contents of arbitrary directories. This is achieved by using a .. (dot dot) in the contentbase parameter to the "rpc/set all" endpoint.

Recommendations For Twonky Server versions 7.0.11 through 8.5, consider restricting access to the contentbase parameter in the "rpc/set all" endpoint to minimize the risk of exploitation. As a temporary workaround, avoid using the contentbase parameter with untrusted input until a patch is available.
