CriticalCVSS 9.8 · v3.0—Weaponized Fix available

Noroxi assessment

Priority: This week (action score 68/100)

  • A ready-made attack module is public (Metasploit, Nuclei); exploiting it takes no special expertise.
  • Public proof-of-concept code exists (Exploit-DB, GitHub); there is no record of exploitation in the wild.
  • Probability of exploitation in the next 30 days: 96.9% (FIRST EPSS); higher than 99.8% of all records.
  • Anyone who can reach it over the internet can trigger it. No account or password is required. No user action is required. No special conditions are required; it is repeatable.
  • Fixed version: org.jenkins-ci.main:jenkins-core (Maven) 2.32, 2.19.3.

Don’t wait for the next maintenance window. Upgrade to org.jenkins-ci.main:jenkins-core (Maven) 2.32, 2.19.3 or later.

Primary sources: NVD · CVE.org · FIRST EPSS

The remoting module in Jenkins before 2.32 and LTS before 2.19.3 allows remote attackers to execute arbitrary code via a crafted serialized Java object, which triggers an LDAP query to a third-party server.
