CVE-2023-38994 (GCVE-0-2023-38994)

Vulnerability from cvelistv5 – Published: 2023-10-31 00:00 – Updated: 2025-04-15 22:09

Summary

The 'check_univention_joinstatus' prometheus monitoring script (and other scripts) in UCS 5.0-5 revealed the LDAP plaintext password of the machine account in the process list allowing attackers with local ssh access to gain higher privileges and perform followup attacks.
