Network-reachable LDAP write (AV:N/AC:L), attacker needs delegated directory write privileges so PR:L not PR:N, and injected sudoRole yields full root impact (C/I/A:H); S:U kept per vendor though cross-host reach arguably warrants S:C.

DescriptionCVE.org

A flaw was found in SSSD's LDAP sudo provider. When the ldap_sudo_search_base option is not explicitly configured, SSSD searches the entire LDAP directory tree for sudoRole objects. An authenticated attacker with write access to any subtree can inject a sudoRole object granting root-level sudo privileges on all SSSD-enrolled hosts.

AnalysisAI

Local-to-domain-wide root privilege escalation in SSSD's LDAP sudo provider allows an authenticated LDAP directory user with write access to any subtree to inject a malicious sudoRole object and gain root-level sudo on every SSSD-enrolled host. The flaw exists because, when ldap_sudo_search_base is left unset, SSSD searches the entire directory tree for sudoRole objects, trusting rules planted anywhere in the DIT. Rated CVSS 8.8 by Red Hat and reported against RHEL 6 through 10 and OpenShift Container Platform 4; no public exploit identified at time of analysis and it is not listed in CISA KEV.

Technical ContextAI

SSSD (System Security Services Daemon) is the identity, authentication, and access-control broker that ties Linux hosts to central directories such as LDAP, FreeIPA, and Active Directory. Its sudo provider fetches sudoRole objects from LDAP to centrally manage sudoers policy. The ldap_sudo_search_base option is meant to constrain where SSSD looks for these objects; when it is not explicitly configured, SSSD falls back to searching from the directory root, so a sudoRole placed in ANY writable branch of the tree is honored. This maps to CWE-1188 (insecure default resource initialization): the insecure default scope, not a memory-safety or parsing bug, is the root cause - the Red Hat 'Code Injection' tag refers to injecting an authorization object rather than executable code.

RemediationAI

No vendor-released patch version was identified in the provided data - monitor the Red Hat advisory (https://access.redhat.com/security/cve/CVE-2026-14474) and Bugzilla 2496556 (https://bugzilla.redhat.com/show_bug.cgi?id=2496556) for the fixed SSSD package build for your RHEL/OpenShift release and apply it once published. The most effective immediate compensating control is to explicitly set ldap_sudo_search_base in the [domain] section of sssd.conf to the specific, tightly-controlled OU where legitimate sudoRole objects live (e.g. ou=SUDOers,dc=example,dc=com), which stops SSSD from honoring rogue objects planted elsewhere; the trade-off is that any legitimately-used sudo rules outside that base will stop applying, so inventory existing sudoRole locations first. Additionally, tighten LDAP directory ACLs so ordinary authenticated users cannot create or modify objects in arbitrary subtrees, and audit the directory for unexpected sudoRole entries. Restart SSSD and clear its cache (sss_cache -E) after configuration changes.
