CVE-2020-10104Network attack vector

Authenticated password-hash disclosure via session response

Published Mar 5, 2020 · Updated Aug 4, 2024

Sensitive information exposure in Zammad 1.0.x through 3.2.0 allows remote authenticated users to retrieve their password hashes. The authenticated session-response path includes the requesting user's hashed password when a certain URL is visited; the vendor has not identified the endpoint or responsible code. A valid account and network access are required, and exposure enables compromise of the returned hash and subsequent unauthorized access.
