Descriptions

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.

Transmission, hasta la versión 2.92, confía en X-Transmission-Session-Id (que no es una cabecera prohibida para Fetch) para el control de acceso, lo que permite que atacantes remotos ejecuten comandos RPC arbitrarios y escriban en archivos arbitrarios mediante peticiones POST en /transmission/rpc, en combinación con un ataque de DNS rebinding.

It was discovered that Transmission incorrectly handled certain POST requests to the RPC server and allowed DNS rebinding attack. An attacker could possibly use this issue to execute arbitrary code.
