CVE-2020-16136
In tgstation-server 4.4.0 and 4.4.1, an authenticated user with permission to download logs can download any file on the server machine (accessible by the owner of the server process) via directory traversal ../ sequences in /Administration/Logs/…
Does this matter?
High impact if exploited, but EPSS currently rates exploitation as unlikely (2.06%). Schedule it in the normal patch cycle and watch for a rise in EPSS or a public exploit.
Description
In tgstation-server 4.4.0 and 4.4.1, an authenticated user with permission to download logs can download any file on the server machine (accessible by the owner of the server process) via directory traversal ../ sequences in /Administration/Logs/ requests. The attacker is unable to enumerate files, however.
