CVE-2023-32978Network attack vector

Attacker-chosen LDAP connections via missing POST enforcement

Published May 16, 2023 · Updated Jan 23, 2025

Cross-site request forgery in Jenkins LDAP Plugin 673.v034ec70ec2b_b_ and earlier allows remote attackers to initiate LDAP connections. The affected form validation method accepts non-POST requests and uses supplied server and credential values to make the connection. A victim must submit a crafted request to a reachable Jenkins controller; the resulting LDAP attempt targets an attacker-selected server with attacker-specified credentials.
