The session.lua library in CGILua 5.2 alpha 1 and 5.2 alpha 2 uses weak session IDs generated based on OS time, which allows remote attackers to hijack arbitrary sessions via a brute force attack.
The session.lua library in CGILua 5.0.x uses sequential session IDs, which makes it easier for remote attackers to predict the session ID and hijack arbitrary sessions.
