Password disclosure via cleartext session storage
Published Apr 28, 2021 · Updated Aug 4, 2024
Cleartext password storage in Etherpad before 1.8.3 allows attackers with database or log access to read user credentials. SessionStore.set passes the session object, including sess.user.password, directly to db.set, so every supported backend receives the cleartext credential and the same value can enter logs. Exploitation requires access to stored session records or logs; the bounded consequence is disclosure of user and administrator passwords.
