CVE-2016-9575: Ipa versions 4.2.x, 4.3.x before 4.3.3 and 4.4.x before 4.4.3 did not properly check the user's permissions while modifying certificate…

MediumCVSS 6.3 · v3.0—No exploit Fix available

Noroxi assessment

Priority: Monitor (action score 25/100)

  • 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: 0.79% (FIRST EPSS); higher than 57.1% 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) 4.4.4-1; ipa (Red Hat:enterprise_linux:7::client) 0:4.4.0-14.el7_3.1.1; ipa-admintools (Red Hat:enterprise_linux:7::client) 0:4.4.0-14.el7_3.1.1.

Low priority for now. Upgrade to freeipa (Debian:12) 4.4.4-1; ipa (Red Hat:enterprise_linux:7::client) 0:4.4.0-14.el7_3.1.1; ipa-admintools (Red Hat:enterprise_linux:7::client) 0:4.4.0-14.el7_3.1.1 or later.

Primary sources: NVD · CVE.org · FIRST EPSS

Ipa versions 4.2.x, 4.3.x before 4.3.3 and 4.4.x before 4.4.3 did not properly check the user's permissions while modifying certificate profiles in IdM's certprofile-mod command. An authenticated, unprivileged attacker could use this flaw to modify profiles to issue certificates with arbitrary naming or key usage information and subsequently use such certificates for other attacks.
