CVE-2020-9330Public exploitNetwork attack vector

LDAP credential theft via unvalidated server redirection

Published Feb 21, 2020 · Updated Aug 4, 2024

Missing authentication in Xerox WorkCentre firmware before 073.xxx.000.02300 allows remote authenticated users to steal LDAP bind credentials. The WebUI accepts an attacker-controlled LDAP server address without reentering or validating the stored bind credentials, then sends those credentials in plaintext during a later directory search. Access to the printer's administrative interface and an existing LDAP configuration are required; exposed credentials enable Active Directory access at the account's privilege level.
