Noroxi assessment

Priority: Plan (action score 55/100)

  • Public proof-of-concept code exists (GitHub); there is no record of exploitation in the wild.
  • Probability of exploitation in the next 30 days: 67.1% (FIRST EPSS); higher than 99.3% of all records.
  • Anyone who can reach it over the internet can trigger it. No account or password is required. A user must open a link or visit a page. No special conditions are required; it is repeatable.
  • Fixed version: org.jenkins-ci.main:jenkins-core (Maven) 2.426.3, 2.442; jenkins (Red Hat:ocp_tools:4.11::el8) 0:2.426.3.1706516929-3.el8; jenkins-2-plugins (Red Hat:ocp_tools:4.11::el8) 0:4.11.1706516946-1.el8.

Add it to your regular patch cycle. Upgrade to org.jenkins-ci.main:jenkins-core (Maven) 2.426.3, 2.442; jenkins (Red Hat:ocp_tools:4.11::el8) 0:2.426.3.1706516929-3.el8; jenkins-2-plugins (Red Hat:ocp_tools:4.11::el8) 0:4.11.1706516946-1.el8 or later.

Primary sources: NVD · CVE.org · FIRST EPSS

Jenkins 2.217 through 2.441 (both inclusive), LTS 2.222.1 through 2.426.2 (both inclusive) does not perform origin validation of requests made through the CLI WebSocket endpoint, resulting in a cross-site WebSocket hijacking (CSWSH) vulnerability, allowing attackers to execute CLI commands on the Jenkins controller.

Variant candidates

Same product, same weakness class, within 18 months. If the patch missed the root cause, the sibling bug is here.

No nightly-computed relations.

Chain candidates

An authentication bypass and a privilege-requiring bug in the same product, published close together: combined they may become an unauthenticated path.
