CVE-2022-4361· NVD / CVE Program· CNA redhat

Keycloak, an open-source identity and access management solution, has a cross-site scripting (XSS) vulnerability in the SAML or OIDC provide

Noroxi assessment

Priority: Monitor (action score 24/100)

  • Public proof-of-concept code exists (GitHub); there is no record of exploitation in the wild.
  • Probability of exploitation in the next 30 days: 0.69% (FIRST EPSS); higher than 52.3% 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.
  • According to CISA the attack is automatable: targets can be found by mass scanning.
  • Fixed version: org.keycloak:keycloak-services (Maven) 21.1.2; rh-sso7-keycloak (Red Hat:red_hat_single_sign_on:7.6::el7) 0:18.0.8-1.redhat_00001.1.el7sso; rh-sso7-keycloak-server (Red Hat:red_hat_single_sign_on:7.6::el7) 0:18.0.8-1.redhat_00001.1.el7sso.
  • Severity is disputed: the assigning authority (CNA) scores it 10.0, NVD 6.1.

Low priority for now. Upgrade to org.keycloak:keycloak-services (Maven) 21.1.2; rh-sso7-keycloak (Red Hat:red_hat_single_sign_on:7.6::el7) 0:18.0.8-1.redhat_00001.1.el7sso; rh-sso7-keycloak-server (Red Hat:red_hat_single_sign_on:7.6::el7) 0:18.0.8-1.redhat_00001.1.el7sso or later.
