Description

Jenkins LDAP Plugin 673.v034ec70ec2b_b_ and earlier does not require POST requests for a form validation method, resulting in a cross-site request forgery (CSRF) vulnerability.

This vulnerability allows attackers to connect to an attacker-specified LDAP server using attacker-specified credentials.

LDAP Plugin 676.vfa_64cf6b_b_002 requires POST requests for the affected form validation method.

Detection & mitigation playbook

Open-source dependency

  1. Detect

    Scan your dependency tree (package-lock.json, pnpm-lock.yaml, requirements.txt, go.sum, etc.) for org.jenkins-ci.plugins:ldap, including transitive dependencies — a direct dependency you never call can still pull in a vulnerable version.

  2. Fix

    Update org.jenkins-ci.plugins:ldap to 676.vfa or later, then make sure no transitive (indirect) dependency still pins the vulnerable range — O3 confirms CVE-2023-32978 is resolved across your whole dependency graph.

  3. Workarounds

    If you can't upgrade right away: gate or disable the affected feature, validate untrusted input at the boundary, and avoid passing attacker-controlled data into the vulnerable path. O3's runtime protection blocks exploitation in production as an interim safeguard until the upgrade lands.
