CVE-2026-14474: Initialization of a Resource with an Insecure Default in Red Hat Red Hat Enterprise Linux 10
CVE-2026-14474 is a high-severity vulnerability in Red Hat Enterprise Linux 10's SSSD LDAP sudo provider. If the ldap_sudo_search_base option is not explicitly set, SSSD searches the entire LDAP directory tree for sudoRole objects. This allows an authenticated attacker with write access to any LDAP subtree to inject a sudoRole object that grants root-level sudo privileges on all hosts enrolled with SSSD.
AI Analysis
Technical Summary
The vulnerability arises from SSSD's LDAP sudo provider default behavior when ldap_sudo_search_base is unset. Instead of limiting the search scope, SSSD searches the entire LDAP directory tree for sudoRole objects. An attacker who is authenticated and has write permissions to any LDAP subtree can exploit this by injecting a sudoRole object that grants root-level sudo privileges across all SSSD-enrolled hosts, effectively escalating privileges to root.
Potential Impact
An authenticated attacker with write access to any LDAP subtree can escalate privileges to root on all hosts using SSSD by injecting malicious sudoRole objects. This leads to full system compromise with high confidentiality, integrity, and availability impact as indicated by the CVSS score of 8.8.
Mitigation Recommendations
Patch status is not yet confirmed — check the Red Hat advisory at https://access.redhat.com/security/cve/CVE-2026-14474 for current remediation guidance. Until an official fix is available, explicitly configuring the ldap_sudo_search_base option to restrict the LDAP search scope can mitigate the risk by preventing SSSD from searching the entire LDAP directory tree.
