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.

• CWE-22Improper Limitation of a Pathname to a Restricted Directory ('Path Traversal')The product uses external input to construct a pathname that is intended to identify a file or directory that is located underneath a restricted parent directory, but the product does not properly neutralize special elements within the pathname that can cause the pathname to resolve to a location that is outside of the restricted directory.
