Unauthenticated communication interception and modification

Published May 25, 2023 · Updated May 22, 2026

Message-integrity failure in CBOT Chatbot before Core 4.0.3.4 and Panel 4.0.3.7 allows remote attackers to intercept and alter traffic. CBOT has not published the affected channel, protocol, code locus, or missing integrity check that permits interposition. Exploitation requires an on-path network position; the documented consequences include reading or modifying exchanged data and interrupting communications.
