CVE-2023-22964Network attack vector

Unauthenticated account access via random LDAP passwords

Published Jan 20, 2023 · Updated Apr 3, 2025

Authentication bypass in ManageEngine ServiceDesk Plus MSP builds 10600 through 10610 and 13000 through 13003 allows remote attackers to log in. The LDAP authentication process accepts any random password for user details imported from LDAP after those details are modified manually or through an API. LDAP authentication must be enabled, and exploitation grants access as the affected imported user without a valid password.
