{"id":"CVE-2026-79763","summary":"Termix: MFA-critical operations accept the account password as a sole factor (regression of CVE-2026-45749)","details":"Termix is a web-based server management platform with SSH terminal, tunneling, and file editing capabilities. From 2.4.0 until 2.5.1, the POST /users/totp/disable and POST /users/totp/backup-codes endpoints accept the account password as the sole reauthentication factor after a 2.4.0 refactor regressed the two-factor check introduced for CVE-2026-45749. In src/backend/database/routes/user-totp-routes.ts, verifyTotpReauth returns success when bcrypt.compare validates the password, while each endpoint chooses password or totp_code as an interchangeable credential. An attacker who has a victim's authenticated session and knows the password can disable TOTP or regenerate and invalidate backup codes without an authenticator or valid second factor, weakening the account to single-factor authentication. This issue is fixed in version 2.5.1.","aliases":["GHSA-x9h9-f7jc-8jwj"],"modified":"2026-09-26T03:47:43.125115953Z","published":"2026-09-24T16:06:16.816Z","database_specific":{"cna_assigner":"GitHub_M","cwe_ids":["CWE-308"],"osv_generated_from":"https://github.com/CVEProject/cvelistV5/tree/main/cves/2026/79xxx/CVE-2026-79763.json"},"references":[{"type":"WEB","url":"https://github.com/Termix-SSH/Termix/releases/tag/release-2.5.1-tag"},{"type":"ADVISORY","url":"https://github.com/CVEProject/cvelistV5/tree/main/cves/2026/79xxx/CVE-2026-79763.json"},{"type":"ADVISORY","url":"https://github.com/Termix-SSH/Termix/security/advisories/GHSA-x9h9-f7jc-8jwj"},{"type":"ADVISORY","url":"https://nvd.nist.gov/vuln/detail/CVE-2026-79763"},{"type":"FIX","url":"https://github.com/Termix-SSH/Termix/commit/22124e1bc49c8cedad57b31de9c51ad39f3d4432"},{"type":"FIX","url":"https://github.com/Termix-SSH/Termix/commit/ddbdd5c437c2296607dfaa4265d6f63fbc1ca92e"},{"type":"FIX","url":"https://github.com/Termix-SSH/Termix/pull/1067"}],"affected":[{"ranges":[{"type":"GIT","repo":"https://github.com/termix-ssh/termix","events":[{"introduced":"ac24fdcba8c6f00b4945b61b7a15efe152556e5e"},{"fixed":"22124e1bc49c8cedad57b31de9c51ad39f3d4432"},{"fixed":"ddbdd5c437c2296607dfaa4265d6f63fbc1ca92e"}],"database_specific":{"extracted_events":[{"introduced":"2.4.0"},{"fixed":"2.5.1"}],"source":["AFFECTED_FIELD","REFERENCES"]}}],"versions":["release-2.5.0-tag","release-2.4.1-tag","release-2.4.0-tag"],"database_specific":{"source":"https://storage.googleapis.com/cve-osv-conversion/osv-output/CVE-2026-79763.json"}}],"schema_version":"1.9.0","severity":[{"type":"CVSS_V3","score":"CVSS:3.1/AV:N/AC:H/PR:L/UI:N/S:U/C:N/I:H/A:N"}]}
