Jenkins LDAP Plugin 807.v7d7de30930cf and earlier follows LDAP referrals returned by the configured LDAP server. An attacker who controls that LDAP server, or who can tamper with traffic to it, can cause the plugin to follow a referral to an RMI endpoint. This can result in deserialization of attacker-controlled data on the Jenkins controller. When suitable deserialization gadget chains are present on the controller classpath, the issue can be escalated to remote code execution. The flaw is rooted in unsafe handling of unvalidated LDAP referrals that enables attacker-directed outbound connections and subsequent unsafe deserialization behavior.
