Controller: html injection in custom login info

Noroxi assessment

Priority: Monitor (action score 21/100)

  • Public proof-of-concept code exists (GitHub); there is no record of exploitation in the wild.
  • Probability of exploitation in the next 30 days: 0.80% (FIRST EPSS); higher than 56% of all records.
  • Anyone who can reach it over the internet can trigger it. A low-privileged account is enough. A user must open a link or visit a page. No special conditions are required; it is repeatable.
  • Fixed version: automation-controller (Red Hat:ansible_automation_platform:2.3::el8) 0:4.3.11-1.el8ap; automation-controller-cli (Red Hat:ansible_automation_platform:2.3::el8) 0:4.3.11-1.el8ap; automation-controller-server (Red Hat:ansible_automation_platform:2.3::el8) 0:4.3.11-1.el8ap.

Low priority for now. Upgrade to automation-controller (Red Hat:ansible_automation_platform:2.3::el8) 0:4.3.11-1.el8ap; automation-controller-cli (Red Hat:ansible_automation_platform:2.3::el8) 0:4.3.11-1.el8ap; automation-controller-server (Red Hat:ansible_automation_platform:2.3::el8) 0:4.3.11-1.el8ap or later.

Generated automatically from the record's data: CVSS (NVD and CNA), CISA KEV and SSVC, FIRST EPSS, exploit sources, fixed versions. How we calculate it

Primary sources: NVD · CVE.org · FIRST EPSS

An HTML injection flaw was found in Controller in the user interface settings. This flaw allows an attacker to capture credentials by creating a custom login page by injecting HTML, resulting in a complete compromise.

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.
