Description
PILOS (Platform for Interactive Live-Online Seminars) is a frontend for BigBlueButton. Prior to 4.8.0, users with a local account can change their password while logged in. When doing so, all other active sessions are terminated, except for the currently active one. However, the current session’s token remains valid and is not refreshed. If an attacker has previously obtained this session token through another vulnerability, changing the password will not invalidate their access. As a result, the attacker can continue to act as the user even after the password has been changed. This vulnerability is fixed in 4.8.0.

Executive Summary

This vulnerability exists in PILOS (Platform for Interactive Live-Online Seminars) versions prior to 4.8.0. When a user changes their password while logged in, all other active sessions are terminated except the current one. However, the current session's token is not refreshed and remains valid. If an attacker has previously obtained this session token through another vulnerability, they can continue to access the user's account even after the password change, effectively bypassing the password update.

Impact Analysis

An attacker who has obtained a valid session token can maintain unauthorized access to a user's account even after the user changes their password. This means the attacker can continue to act as the user, potentially accessing sensitive information or performing unauthorized actions despite the password change.

Mitigation Strategies

Upgrade PILOS to version 4.8.0 or later, as this version contains the fix that properly invalidates session tokens after a password change, preventing attackers from maintaining access.
