Official Description

Bludit allows user's session identifier to be set before authentication. The value of this session ID stays the same after authentication. This behavior enables an attacker to fix a session ID

for a victim and later hijack the authenticated session.

This issue was fixed in version 3.17.2.

Risk Analysis

This critical vulnerability in Bludit allows for session hijacking due to the session identifier being set before authentication and remaining the same afterward. An attacker can fix a session ID for a victim and then hijack their authenticated session. With a CVSS score of 9.8, this flaw poses a high risk for remote attackers to gain unauthorized access.

No public exploit is currently known for this vulnerability, and it is not listed in CISA's KEV catalog. The attack vector is network-based with low complexity, making it remotely exploitable without requiring any privileges or user interaction.

Recommended Action

Users should update Bludit to version 3.17.2 or later to fix this session fixation vulnerability. Ensure that new session identifiers are generated upon successful authentication to prevent hijacking.
