Summary

Omnispace Agora Project before 26.10.0 contains an authentication bypass. The legacy AGORAP_LOG and AGORAP_PASS cookies treat the stored bcrypt password hash as a replayable credential, which is a use of a password hash instead of a password for authentication (CWE-836). An attacker who holds a user's password hash can set these cookies to log in as that user, including administrators, without knowing the actual password.

Description from the CNA

Omnispace Agora Project before 26.10.0 contains an authentication bypass vulnerability that allows attackers possessing a user's stored bcrypt password hash to authenticate as that user without knowing the actual password, caused by the legacy AGORAP_LOG/AGORAP_PASS cookie mechanism treating the stored hash as a directly replayable bearer credential. Attackers can set the AGORAP_LOG/AGORAP_PASS cookies with a stolen password hash to impersonate any user, including administrators, and gain unauthorized access to the application.
