CVE-2026-14476high8.0

Sssd: sssd: gpo cache path traversal via unsanitized gpcfilesyspath allows kerberos authentication bypass

Impact

A path traversal flaw in SSSD's AD GPO provider allows an attacker with AD GPO management access to write files outside the GPO cache directory, potentially leading to Kerberos authentication bypass. The affected product is Red Hat Enterprise Linux, with various versions listed.

Summarized by @cf/meta/llama-3.3-70b-instruct-fp8-fast. Verify details against the original sources.

What to do

Set ad_gpo_access_control = disabled in /etc/sssd/sssd.conf to disable GPO fetching entirely. Note that this removes GPO-based login policy enforcement.

Original source description

A path traversal flaw was found in SSSD's AD GPO provider. The ad_gpo_extract_smb_components() function does not sanitize .. sequences in the gPCFileSysPath LDAP attribute, allowing an attacker with AD GPO management access to write files outside the GPO cache directory as root. On default RHEL configurations with SELinux enforcing, this can be used to inject Kerberos configuration leading to authentication bypass.
