SFTPGo WebAdmin and WebClient support login using TOTP (Time-based One Time Passwords) as a secondary authentication factor. Because TOTPs are often configured on mobile devices that can be lost, stolen or damaged, SFTPGo also supports recovery codes. These are a set of one time use codes that can be used instead of the TOTP. In SFTPGo versions from version 2.2.0 to 2.3.3 recovery codes can be generated before enabling two-factor authentication. An attacker who knows the user's password could potentially generate some recovery codes and then bypass two-factor authentication after it is enabled on the account at a later time. This issue has been fixed in version 2.3.4. Recovery codes can now only be generated after enabling two-factor authentication and are deleted after disabling it.","state":"PUBLIC","assigner":"security-advisories@github.com","published_at":"2022-09-02 18:15:00","updated_at":"2022-09-09 03:40:00"},"problem_types":["CWE-916"],"metrics":[],"references":[{"url":"https://github.com/drakkan/sftpgo/issues/965","name":"https://github.com/drakkan/sftpgo/issues/965","refsource":"MISC","tags":[],"title":"TOTP Generate Recovery Codes MFA · Issue #965 · drakkan/sftpgo · GitHub","mime":"text/html","httpstatus":"200","archivestatus":"404"},{"url":"https://github.com/drakkan/sftpgo/security/advisories/GHSA-54qx-8p8w-xhg8","name":"https://github.com/drakkan/sftpgo/security/advisories/GHSA-54qx-8p8w-xhg8","refsource":"CONFIRM","tags":[],"title":"Recovery codes abuse · Advisory · drakkan/sftpgo · GitHub","mime":"text/html","httpstatus":"200","archivestatus":"404"},{"url":"https://www.cve.org/CVERecord?id=CVE-2022-36071","name":"CVE Program record","refsource":"CVE.ORG","tags":["canonical"]},{"url":"https://nvd.nist.gov/vuln/detail/CVE-2022-36071","name":"NVD vulnerability detail","refsource":"NVD","tags":["canonical","analysis"]}],"affected":[],"timeline":[],"solutions":[],"workarounds":[],"exploits":[],"credits":[],"nvd_cpes":[{"cve_year":"2022","cve_id":"36071","vulnerable":"1","versionEndIncluding":"","cpe1":"cpe","cpe2":"2.3","cpe3":"a","cpe4":"sftpgo_project","cpe5":"sftpgo","cpe6":"*","cpe7":"*","cpe8":"*","cpe9":"*","cpe10":"*","cpe11":"*","cpe12":"*","cpe13":"*"}],"vendor_comments":[],"enrichments":{"kev":null,"epss":null,"legacy_qids":[]},"source_records":{"cve_program":{"CVE_data_meta":{"ASSIGNER":"security-advisories@github.com","ID":"CVE-2022-36071","STATE":"PUBLIC","TITLE":"Recovery codes abuse in SFTPGo"},"affects":{"vendor":{"vendor_data":[{"product":{"product_data":[{"product_name":"sftpgo","version":{"version_data":[{"version_value":">= 2.2.0, < 2.3.4"}]}}]},"vendor_name":"drakkan"}]}},"data_format":"MITRE","data_type":"CVE","data_version":"4.0","description":{"description_data":[{"lang":"eng","value":"SFTPGo is configurable SFTP server with optional HTTP/S, FTP/S and WebDAV support.
