Description

This security bulletin contains information about 1 security vulnerability.


1) Command injection (CVE-ID: CVE-2018-5702)

The vulnerability allows a remote attacker to execute arbitrary RPC commands on the target system.

The vulnerability exists in the Remote Procedure Call (RPC) session-id mechanism in Transmission due to bthe affected software uses the X-Transmission-Session-Id header for access control. A remote unauthenticated attacker can conduct a DNS rebinding attack, register a domain name and make it resolve to localhost, then delegate the domain name to an attacker-controlled DNS server that is configured to respond with a short time-to-live (TTL) record, trick the victim into following a link that submits malicious input, execute arbitrary RPC commands and arbitrary code with elevated privileges.

Successful exploitation of the vulnerability may result in system compromise.
