CVE-2018-5702 (opens in a new tab)How to fix?
Upgrade Ubuntu:17.10 transmission to version 2.92-2ubuntu3.1 or higher.
NVD Description
Note: Versions mentioned in the description apply only to the upstream transmission package and not the transmission package as distributed by Ubuntu.
See How to fix? for Ubuntu:17.10 relevant fixed versions and status.
Transmission through 2.92 relies on X-Transmission-Session-Id (which is not a forbidden header for Fetch) for access control, which allows remote attackers to execute arbitrary RPC commands, and consequently write to arbitrary files, via POST requests to /transmission/rpc in conjunction with a DNS rebinding attack.
