CVE-2014-10399Network attack vector

Unauthenticated session hijacking via reused identifier

Published Feb 6, 2020 · Updated Aug 6, 2024

Session management in CGILua 5.1.x allows remote attackers to hijack arbitrary user sessions through a reused session identifier. The session.lua identifier generator returns the same value for every session rather than creating a unique, unpredictable value. No authentication is required, but a victim session must exist; presenting the shared identifier grants access to that session's application privileges and data.
