{"id":"CVE-2026-104117","state":"PUBLISHED","title":"Missing authorization in illumos ipmgmtd allows local users to change persistent IPMP group membership","description":"A missing authorization check in the illumos IP management daemon (ipmgmtd) allows a local user to change the persistent IP multipathing (IPMP) configuration. The ipmgmtd door dispatch table in usr/src/cmd/cmd-inet/lib/ipmgmtd/ipmgmt_door.c does not require the solaris.network.interface.config authorization for the IPMGMT_CMD_IPMP_UPDATE command, although its handler, ipmgmt_ipmp_update_handler(), writes to the persistent ipadm configuration when the IPMGMT_PERSIST flag is set. An unprivileged local user can therefore add interfaces to, or remove them from, existing IPMP groups in the stored configuration. The running configuration is not changed; the modification takes effect when the stored configuration is next applied, such as at boot, and may disrupt network connectivity. The flaw has existed since 2021 (illumos-gate commit a73be61a), and affects any illumos distribution prior to illumos-gate commit e8d3efa1.","publishedAt":"2026-10-09T14:15:42.585Z","updatedAt":"2026-10-09T16:45:59.398Z","severity":{"score":1.9,"label":"Low","version":"4.0","vector":"CVSS:4.0/AV:L/AC:L/AT:N/PR:L/UI:N/VC:N/VI:L/VA:L/SC:N/SI:N/SA:N/E:P","source":"illumos"},"assigner":"illumos","products":["illumos illumos-gate","OmniOS OmniOS"],"affected":[{"vendor":"illumos","product":"illumos-gate","packageName":"SUNWcs","defaultStatus":"unaffected","versions":[{"version":"a73be61a80f7331c35adfa540bcf8f1546ff1e33","status":"affected","lessThan":"e8d3efa1c56e5f2b5368600a2baeb7b1d54a07f8","changes":[{"at":"e8d3efa1c56e5f2b5368600a2baeb7b1d54a07f8","status":"unaffected"}],"versionType":"git"}],"platforms":["x86"],"collectionURL":"https://illumos.org","repo":"https://github.com/illumos/illumos-gate","programFiles":["usr/src/cmd/cmd-inet/lib/ipmgmtd/ipmgmt_door.c"]},{"vendor":"OmniOS","product":"OmniOS","defaultStatus":"affected","versions":[{"version":"r151042","status":"affected","lessThan":"r151054","versionType":"custom"},{"version":"r151058","status":"affected","lessThan":"r151058w","changes":[{"at":"r151058w","status":"unaffected"}],"versionType":"custom"},{"version":"r151056","status":"affected","lessThan":"r151056aw","changes":[{"at":"r151056aw","status":"unaffected"}],"versionType":"custom"},{"version":"r151054","status":"affected","lessThan":"r151054bw","changes":[{"at":"r151054bw","status":"unaffected"}],"versionType":"custom"}]}],"references":["https://illumos.topicbox.com/groups/developer/T3b859664594b7762/cve-2026-104112-to-cve-2026-104117-denial-of-service-and-missing-authorization-in-door-servers","https://illumos.org/issues/18492","https://github.com/illumos/illumos-gate/commit/e8d3efa1c56e5f2b5368600a2baeb7b1d54a07f8"],"weaknesses":["CWE-862"],"ingestedAt":"2026-10-29T20:10:23.711Z","source":{"repository":"CVEProject/cvelistV5","path":"cves/2026/104xxx/CVE-2026-104117.json","commit":"556c9d3a8cd17e218bb8e452ba7cd619a384ff47"},"raw":{"dataType":"CVE_RECORD","dataVersion":"5.2","cveMetadata":{"cveId":"CVE-2026-104117","state":"PUBLISHED","datePublished":"2026-10-09T14:15:42.585Z","dateUpdated":"2026-10-09T16:45:59.398Z","assignerShortName":"illumos","assignerOrgId":"0ca53633-f0b5-4853-ba72-e0a2e62000d0","dateReserved":"2026-10-01T18:07:53.956Z"},"containers":{"cna":{"title":"Missing authorization in illumos ipmgmtd allows local users to change persistent IPMP group membership","descriptions":[{"lang":"en","value":"A missing authorization check in the illumos IP management daemon (ipmgmtd) allows a local user to change the persistent IP multipathing (IPMP) configuration.
