The makeSessionKey function in libucrypto.so generates tokens using fixed salts without incorporating channel-specific or session-specific input, and the user service validates tokens against the login store without verifying channel context, enabling stolen tokens to grant persistent administrative access until the token store is explicitly cleared. This vulnerability extends the impact of CVE-2025-61481, which identified the underlying transport-layer exposure without a corresponding fix.","state":0,"publishedAt":"2026-10-21T17:16:40.843+00:00","modifiedAt":"2026-10-28T01:25:56.959+00:00","affected":[{"ecosystem":"Vendor product","name":"RouterOS","ranges":[],"versions":[],"rawVersionEvidence":"{\n                    \"defaultStatus\": \"unknown\",\n                    \"vendor\": \"MikroTik\",\n                    \"product\": \"RouterOS\",\n                    \"versions\": [\n                        {\n                            \"status\": \"affected\",\n                            \"version\": \"0\",\n                            \"versionType\": \"semver\",\n                            \"lessThanOrEqual\": \"7.23.6\"\n                        },\n                        {\n                            \"status\": \"affected\",\n                            \"version\": \"7.24.0\",\n                            \"versionType\": \"semver\",\n                            \"lessThanOrEqual\": \"7.24.5\"\n                        }\n                    ]\n                }"}],"metrics":[{"system":"CVSS 4.0","vector":"CVSS:4.0/AV:N/AC:H/AT:N/PR:N/UI:N/VC:H/VI:H/VA:N/SC:N/SI:N/SA:N","score":9.1,"severity":"CRITICAL"},{"system":"CVSS 3.1","vector":"CVSS:3.1/AV:N/AC:H/PR:N/UI:N/S:U/C:H/I:H/A:N","score":7.4,"severity":"HIGH"}],"references":["https://www.vulncheck.com/advisories/mikrotik-routeros-webfig-session-token-replay-authentication-bypass"],"sourceUrl":"https://www.cve.org/CVERecord?id=CVE-2026-89035","license":"CVE Program Terms of Use","key":"cve-program:CVE-2026-89035","identifiers":["CVE-2026-89035"]},"retained":false,"historicalAffected":[]}],"coverage":[{"source":"cisa-kev:global","scope":"Complete CISA KEV catalog; all vendors.
