CVE-2024-11318Public exploitNetwork attack vector

Unauthenticated session hijacking via brute-forced identifiers

Published Nov 18, 2024 · Updated Nov 18, 2024

IDOR in Baratz AbsysNet 2.3.1 allows remote attackers to hijack active user sessions through the /cgi-bin/ocap/ endpoint. The endpoint accepts guessable session identifiers and returns an authenticated user's token in HTML when a brute-forced identifier matches. No authentication or user interaction is required, but a victim session must be active, and access ends when that user logs out.
