CVE-2023-36136Public exploitNetwork attack vector

Password disclosure via cleartext user-edit fields

Published Aug 8, 2023 · Updated Oct 10, 2024

Cleartext password exposure in PHPJabbers Class Scheduling System 1.0 allows remote authenticated users to read every user's password. The user-edit page returns stored passwords as plaintext in its password field instead of withholding or irreversibly protecting them. Access to the administrative user editor is required, and the demonstrated consequence is disclosure of credentials for all application users.
