NVD-CWE-noinfoPublished: January 15, 2018· Updated: Jun 17, 2026

8.8
CVSS v3.1

Official Description

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.

Technical Analysis

CVE-2018-5702 can be exploited remotely over the network without requiring physical or adjacent access, significantly expanding the attack surface for threat actors.

Exploitation does not require any privileges, though user interaction (Required) is needed, which slightly reduces the risk of mass automated attacks.

A successful exploit results in complete confidentiality breach (data exposure), full integrity compromise (data manipulation), availability disruption (denial of service), with a CVSS base score of 8.8.

A proof-of-concept (PoC) exploit exists for CVE-2018-5702. While not yet confirmed in active campaigns, the availability of PoC code increases exploitation risk substantially.
