VUL-0: CVE-2022-4254: sssd: libsss_certmap fails to sanitise certificate data used in LDAP filters
Last modified: 2024-05-03 09:58:57 UTC
rh#2149894 FreeIPA supports the Kerberos PKINIT protocol extension (RFC 4556). PKINIT enables a client to authenticate to the KDC using an X.509 certificate and the corresonding private key, rather than a passphrase or keytab. FreeIPA uses mapping rules to map a certificate presented during a PKINIT authentication request to the corresponding principal. The mapping filter is vulnerable to LDAP filter injection. The search result can be influenced by values in the certificate, which may be attacker controlled. In the most extreme case, an attacker could gain control of the admin account, leading to full domain takeover. FreeIPA is not vulnerable in its default configuration. The problem is in libsss_certmap, which is part of SSSD. FreeIPA servers use this library in ipa_kdb Kerberos plugin implementation. The issue was introduced in SSSD 1.15.3 (when libsss_certmap was introduced) and resolved in SSSD 2.3.1.
