Description
A path traversal vulnerability was found in the VPN Clients on the ADM. The vulnerability occurs because user-controlled certificate name input is not sufficiently validated before being used to construct the upload destination path. An authenticated attacker can exploit this issue to write an uploaded certificate file outside the intended VPN certificate directory, subject to process privileges and filesystem permissions.
Affected products and versions include: from ADM 4.1.0 through ADM 4.3.3.RUN1 as well as from ADM 5.0.0 through ADM 5.1.3.RI81.
