MediumCVSS 6.5 · v3.0—No exploit Fix available

Noroxi assessment

Priority: Monitor (action score 27/100)

  • The sources we track (CISA KEV, Exploit-DB, Metasploit, Nuclei, GitHub) show no public exploit code or exploitation in the wild.
  • Probability of exploitation in the next 30 days: 2.6% (FIRST EPSS); higher than 85.6% of all records.
  • Anyone who can reach it over the internet can trigger it. A low-privileged account is enough. No user action is required. No special conditions are required; it is repeatable.
  • Fixed version: freeipa (Debian:12) 4.3.2-5; ipa (Red Hat:enterprise_linux:6::client) 0:3.0.0-50.el6_8.2; ipa-admintools (Red Hat:enterprise_linux:6::client) 0:3.0.0-50.el6_8.2.

Low priority for now. Upgrade to freeipa (Debian:12) 4.3.2-5; ipa (Red Hat:enterprise_linux:6::client) 0:3.0.0-50.el6_8.2; ipa-admintools (Red Hat:enterprise_linux:6::client) 0:3.0.0-50.el6_8.2 or later.

Primary sources: NVD · CVE.org · FIRST EPSS

The cert_revoke command in FreeIPA does not check for the "revoke certificate" permission, which allows remote authenticated users to revoke arbitrary certificates by leveraging the "retrieve certificate" permission.
