Subject: CVE-2024-27905: Apache Aurora: padding oracle can allow
 construction an authentication cookie 

Severity: important

Affected versions:

- Apache Aurora 0.5.0 or later


** UNSUPPORTED WHEN ASSIGNED ** Exposure of Sensitive Information to an Unauthorized Actor vulnerability in Apache Aurora.

An endpoint exposing internals to unauthenticated users can be used as a "padding oracle" allowing an anonymous attacker to construct a valid authentication cookie. Potentially this could be combined with vulnerabilities in other components to achieve remote code execution.

As this project is retired, we do not plan to release a version that fixes this issue. Users are recommended to find an alternative or restrict access to the instance to trusted users.

NOTE: This vulnerability only affects products that are no longer supported by the maintainer.
