{"id":"CVE-2025-11561","summary":"Sssd: sssd default kerberos configuration allows privilege escalation on ad-joined linux systems","details":"A flaw was found in the integration of Active Directory and the System Security Services Daemon (SSSD) on Linux systems. In default configurations, the Kerberos local authentication plugin (sssd_krb5_localauth_plugin) is enabled, but a fallback to the an2ln plugin is possible. This fallback allows an attacker with permission to modify certain AD attributes (such as userPrincipalName or samAccountName) to impersonate privileged users, potentially resulting in unauthorized access or privilege escalation on domain-joined Linux hosts.","modified":"2026-11-05T21:15:37.715743583Z","published":"2025-10-09T13:37:53.089Z","related":["ALSA-2025:19610","ALSA-2025:20954","ALSA-2025:21020","SUSE-SU-2025:21066-1","SUSE-SU-2025:21084-1","SUSE-SU-2025:4181-1","SUSE-SU-2025:4182-1","SUSE-SU-2025:4183-1","SUSE-SU-2025:4231-1","SUSE-SU-2025:4232-1","SUSE-SU-2025:4247-1","SUSE-SU-2026:20014-1","SUSE-SU-2026:20019-1","openSUSE-SU-2025:15751-1","openSUSE-SU-2026:20001-1"],"database_specific":{"osv_generated_from":"https://github.com/CVEProject/cvelistV5/tree/main/cves/2025/11xxx/CVE-2025-11561.json","unresolved_ranges":[{"extracted_events":[{"range":[{"fixed":"0:2.10.2-3.el10_0.3"},{"fixed":"0:2.11.1-2.el10_1.1"},{"fixed":"0:1.16.5-10.el7_9.17"},{"fixed":"0:2.9.4-5.el8_10.3"},{"fixed":"0:2.9.4-5.el8_10.3"},{"fixed":"0:2.2.3-20.el8_2.3"},{"fixed":"0:2.4.0-9.el8_4.4"},{"fixed":"0:2.4.0-9.el8_4.4"},{"fixed":"0:2.6.2-4.el8_6.4"},{"fixed":"0:2.6.2-4.el8_6.4"},{"fixed":"0:2.6.2-4.el8_6.4"},{"fixed":"0:2.8.2-4.el8_8.3"},{"fixed":"0:2.8.2-4.el8_8.3"},{"fixed":"0:2.9.7-4.el9_7.1"},{"fixed":"0:2.9.7-4.el9_7.1"},{"fixed":"0:2.6.2-4.el9_0.4"},{"fixed":"0:2.8.2-5.el9_2.6"},{"fixed":"0:2.9.4-6.el9_4.4"},{"fixed":"0:2.9.6-4.el9_6.3"},{"fixed":"412.86.202601061735-0"},{"fixed":"413.92.202601130113-0"},{"fixed":"414.92.202511122212-0"},{"fixed":"415.92.202512100122-0"},{"fixed":"416.94.202512030118-0"},{"fixed":"417.94.202511260612-0"},{"fixed":"418.94.202511170715-0"},{"fixed":"4.19.9.6.202511252219-0"},{"fixed":"4.20.9.6.202511252309-0"},{"fixed":"7"},{"fixed":"8"}],"source":"AFFECTED_FIELD","strategy":"InverseAffectedRanges"}]}],"cna_assigner":"redhat","cwe_ids":["CWE-269"]},"references":[{"type":"WEB","url":"https://access.redhat.com/downloads/content/package-browser/"},{"type":"WEB","url":"https://catalog.redhat.com/software/containers/"},{"type":"WEB","url":"https://sssd.io/"},{"type":"ADVISORY","url":"https://access.redhat.com/errata/RHSA-2025:19610"},{"type":"ADVISORY","url":"https://access.redhat.com/errata/RHSA-2025:19847"},{"type":"ADVISORY","url":"https://access.redhat.com/errata/RHSA-2025:19848"},{"type":"ADVISORY","url":"https://access.redhat.com/errata/RHSA-2025:19849"},{"type":"ADVISORY","url":"https://access.redhat.com/errata/RHSA-2025:19850"},{"type":"ADVISORY","url":"https://access.redhat.com/errata/RHSA-2025:19851"},{"type":"ADVISORY","url":"https://access.redhat.com/errata/RHSA-2025:19852"},{"type":"ADVISORY","url":"https://access.redhat.com/errata/RHSA-2025:19853"},{"type":"ADVISORY","url":"https://access.redhat.com/errata/RHSA-2025:19854"},{"type":"ADVISORY","url":"https://access.redhat.com/errata/RHSA-2025:19859"},{"type":"ADVISORY","url":"https://access.redhat.com/errata/RHSA-2025:20954"},{"type":"ADVISORY","url":"https://access.redhat.com/errata/RHSA-2025:21020"},{"type":"ADVISORY","url":"https://access.redhat.com/errata/RHSA-2025:21067"},{"type":"ADVISORY","url":"https://access.redhat.com/errata/RHSA-2025:21329"},{"type":"ADVISORY","url":"https://access.redhat.com/errata/RHSA-2025:21795"},{"type":"ADVISORY","url":"https://access.redhat.com/errata/RHSA-2025:22256"},{"type":"ADVISORY","url":"https://access.redhat.com/errata/RHSA-2025:22265"},{"type":"ADVISORY","url":"https://access.redhat.com/errata/RHSA-2025:22277"},{"type":"ADVISORY","url":"https://access.redhat.com/errata/RHSA-2025:22529"},{"type":"ADVISORY","url":"https://access.redhat.com/errata/RHSA-2025:22548"},{"type":"ADVISORY","url":"https://access.redhat.com/errata/RHSA-2025:22724"},{"type":"ADVISORY","url":"https://access.redhat.com/errata/RHSA-2025:23113"},{"type":"ADVISORY","url":"https://access.redhat.com/errata/RHSA-2026:0316"},{"type":"ADVISORY","url":"https://access.redhat.com/errata/RHSA-2026:0677"},{"type":"ADVISORY","url":"https://access.redhat.com/security/cve/CVE-2025-11561"},{"type":"ADVISORY","url":"https://github.com/CVEProject/cvelistV5/tree/main/cves/2025/11xxx/CVE-2025-11561.json"},{"type":"ADVISORY","url":"https://nvd.nist.gov/vuln/detail/CVE-2025-11561"},{"type":"REPORT","url":"https://bugzilla.redhat.com/show_bug.cgi?id=2402727"},{"type":"REPORT","url":"https://github.com/SSSD/sssd/issues/8021"},{"type":"ARTICLE","url":"https://blog.async.sg/kerberos-ldr"}],"affected":[{"ranges":[{"type":"GIT","repo":"https://github.com/sssd/sssd","events":[{"introduced":"0"},{"last_affected":"ced937c9d3818567c59f624379e61be0004edf2f"}],"database_specific":{"extracted_events":[{"range":[{"introduced":"0"},{"last_affected":"2.11.1"}],"source":"AFFECTED_FIELD","strategy":"StandardRange"}]}}],"versions":["2.11.1","2.11.0","2.10.0","2.10.0-beta2","2.10.0-beta1","2.9.0","2.8.0","2.7.0","2.6.3","2.6.2","2.6.1","2.6.0","2.5.2","2.5.1","2.5.0","2.4.2","2.4.1","sssd-2_4_0","sssd-2_3_1","sssd-2_3_0","sssd-2_2_3","sssd-2_2_2","sssd-2_2_1","sssd-2_2_0","sssd-2_1_0","sssd-1_16_3","sssd-1_16_2","sssd-1_16_1","sssd-1_16_0","sssd-1_15_3","sssd-1_15_2","sssd-1_15_1","sssd-1_15_0","sssd-1_14_2","sssd-1_14_1","sssd-1_14_0","sssd-1_14_0_beta1","sssd-1_13_91","sssd-1_14_0_alpha1","sssd-1_13_90","
