|---|---|---|---|---|---|---|---|---|
| CVE-2012-3462 | Hig | 0.57 | 8.8 | 0.02 | Dec 26, 2019 | A flaw was found in SSSD version 1.9.0. The SSSD's access-provider logic causes the result of the HBAC rule processing to be ignored in the event that the access-provider is also handling the setup of the user's SELinux user context. | ||
| CVE-2026-14476 | Hig | 0.45 | 8.0 | 0.01 | Jul 7, 2026 | 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.… | ||
| CVE-2026-87853 | Hig | 0.42 | 7.5 | 0.00 | Sep 9, 2026 | A flaw was found in SSSD's IdP authentication provider. The eval_access_token_buf() function compares the OIDC subject identifier using strncmp() with the authenticated user's identifier length, performing a prefix comparison instead of an exact match. An attacker whose IdP… | ||
| CVE-2026-68743 | Med | 0.36 | 5.5 | 0.00 | Aug 4, 2026 | A flaw was found in SSSD. The extract_authtok_v1() function in the PAM responder does not validate the auth_token_length field against the remaining buffer size before processing. A local attacker can exploit this via a crafted protocol v1 request to the PAM responder socket,… | ||
| CVE-2026-90462 | Med | 0.35 | 5.4 | 0.00 | Sep 22, 2026 | A flaw was found in SSSD. When configured with the LDAP access provider and `ldap_access_order` including `ppolicy` or `lockout`, a fail-open condition in the LDAP ppolicy access check can occur if a user lookup returns zero results. This can incorrectly return success and cache… | ||
| CVE-2018-16838 | Med | 0.35 | 5.4 | 0.01 | Mar 25, 2019 | A flaw was found in sssd Group Policy Objects implementation. When the GPO is not readable by SSSD due to a too strict permission settings on the server side, SSSD will allow all authenticated users to login instead of denying access. | ||
| CVE-2017-12173 | Med | 0.28 | 4.3 | 0.01 | Jul 27, 2018 | It was found that sssd's sysdb_search_user_by_upn_res() function before 1.16.0 did not sanitize requests when querying its local cache and was vulnerable to injection. In a centralized login environment, if a password hash was locally cached for a given user, an authenticated… | ||
| CVE-2026-90996 | Med | 0.26 | 4.0 | 0.00 | Sep 14, 2026 | A flaw was found in sssd. A local unprivileged user could send a specially crafted request with a zero-length body to the Network Security Services (NSS) responder. This could lead to a denial-of-service condition, causing the NSS responder to become unstable or terminate. This… | ||
| CVE-2026-90463 | Med | 0.26 | 4.0 | 0.00 | Sep 14, 2026 | A flaw was found in the sssd NSS responder. This input validation vulnerability allows a local attacker, by sending specially crafted service lookup requests to the NSS responder's UNIX socket, to cause an out-of-bounds read. This out-of-bounds read may lead to a denial of… | ||
| CVE-2026-68744 | Low | 0.21 | 3.3 | 0.00 | Aug 4, 2026 | A flaw was found in SSSD. The sss_nss_protocol_fill_initgr() function in the NSS responder pre-allocates reply space for all group entries but does not shrink the packet when groups are skipped, causing uninitialized heap bytes to be transmitted to the client. A local attacker… | ||
| CVE-2023-3758 | Hig | 0.00 | 7.1 | 0.01 | Apr 18, 2024 | A race condition flaw was found in sssd where the GPO policy is not consistently applied for authenticated users. This may lead to improper authorization issues, granting or denying access to resources inappropriately. | ||
| CVE-2013-0287 | 0.00 | — | 0.02 | Mar 21, 2013 | The Simple Access Provider in System Security Services Daemon (SSSD) 1.9.0 through 1.9.4, when the Active Directory provider is used, does not properly enforce the simple_deny_groups option, which allows remote authenticated users to bypass intended access restrictions. |
