Freeipa: user can obtain a hash of the passwords of all domain users and perform offline brute force
Noroxi assessment
Priority: Monitor (action score 33/100)
- Public proof-of-concept code exists (GitHub); there is no record of exploitation in the wild.
- Probability of exploitation in the next 30 days: 2% (FIRST EPSS); higher than 80.9% 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: bind-dyndb-ldap (AlmaLinux:8) 11.6-5.module_el8.10.0+3844+20e075e5.alma.2; custodia (AlmaLinux:8) 0.6.0-3.module_el8.6.0+2881+2f24dc92; ipa-client (AlmaLinux:8) 4.9.13-10.module_el8.10.0+3857+9c8da539.
Low priority for now. Upgrade to bind-dyndb-ldap (AlmaLinux:8) 11.6-5.module_el8.10.0+3844+20e075e5.alma.2; custodia (AlmaLinux:8) 0.6.0-3.module_el8.6.0+2881+2f24dc92; ipa-client (AlmaLinux:8) 4.9.13-10.module_el8.10.0+3857+9c8da539 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
A vulnerability was found in FreeIPA in a way when a Kerberos TGS-REQ is encrypted using the client’s session key. This key is different for each new session, which protects it from brute force attacks. However, the ticket it contains is encrypted using the target principal key directly. For user principals, this key is a hash of a public per-principal randomly-generated salt and the user’s password. If a principal is compromised it means the attacker would be able to retrieve tickets encrypted to any principal, all of them being encrypted by their own key directly. By taking these tickets and salts offline, the attacker could run brute force attacks to find character strings able to decrypt tickets when combined to a principal salt (i.e. find the principal’s password).
