Technical Details

Vulnerability Mechanism & Technical Analysis

This vulnerability is classified under CWE-384: Session Fixation, where authenticating a user, or otherwise establishing a new user session, without invalidating any existing session identifier gives an attacker the opportunity to steal authenticated sessions. In Alextselegidis/easyappointments, software state validation or input boundaries are circumvented during processing. Review the official source advisory statement below for specific affected components, classes, and reproduction details.

Source Advisory Statement

alextselegidis/easyappointments is vulnerable to session fixation. The application does not generate a new `ea_session` cookie after the user authenticates. A malicious user may create a new session cookie value and inject it to a victim. After the victim logs in, the injected cookie becomes valid, giving the attacker access to the user's account through the active session. If an attacker conducts this attack against an admin user, the attacker may escalate their privileges with the admin user being unaware. This issue is patched in commit 7f37350fab9d729a9350d96369ff0f453cf7b840 and anticipated to be part of version 1.5.0.
