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. …

Vulnerability AssessmentAI

Exploitation Exploitation requires two concrete conditions from the description: (1) the SSSD LDAP sudo provider is in use with the ldap_sudo_search_base option NOT explicitly configured, causing SSSD to search the entire LDAP directory tree for sudoRole objects; and (2) the attacker is an authenticated directory principal holding write access to at least one subtree of the LDAP directory, sufficient to create a sudoRole object. … Additional conditions and limiting factors are described in the full assessment.
Risk Assessment The CVSS 3.1 vector (AV:N/AC:L/PR:L/UI:N/S:U/C:H/I:H/A:H = 8.8 High) accurately captures a network-reachable, low-complexity attack that requires some existing privilege (PR:L) - specifically write access to a directory subtree - and yields full confidentiality, integrity, and availability impact via root sudo. … Full risk analysis with EPSS, KEV, and SSVC signal comparison available after sign-in.
Exploit Scenario An authenticated directory user who has been delegated write access to a seemingly harmless subtree (for example, their own group or department OU) creates a sudoRole object granting themselves ALL=(ALL) NOPASSWD on all hosts. Because the victim organization never set ldap_sudo_search_base, every SSSD-enrolled server discovers and applies the injected rule on its next sudo lookup, and the attacker runs commands as root across the fleet. …
Remediation 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. … Detailed patch versions, workarounds, and compensating controls in full report.

Recommended ActionAI

Within 24 hours: Inventory all RHEL 6-10 and OpenShift Container Platform 4 systems using SSSD with LDAP sudo integration; audit LDAP directory permissions to identify which user accounts have write access to sudoRole objects. …
