Attackers holding a hijacked session can submit key=2fa with a null JSON value to SetConfigController, stripping 2FA so later logins require only the MySQL password.","cvssScore":4.3,"cvssSeverity":"MEDIUM","cvssVector":"CVSS:3.1/AV:N/AC:L/PR:L/UI:N/S:U/C:N/I:L/A:N","cwes":["CWE-620"],"vendors":[],"products":[],"references":[{"url":"https://abraxaslabs.tech/research/phpmyadmin-config-set-2fa","tags":[]},{"url":"https://github.com/phpmyadmin/phpmyadmin","tags":[]},{"url":"https://github.com/phpmyadmin/phpmyadmin/blob/RELEASE_5_2_3/libraries/classes/Controllers/Config/SetConfigController.php#L29-L41","tags":[]},{"url":"https://github.com/phpmyadmin/phpmyadmin/commit/6482dfa28bd56d515f482b008b194a516646fe1b","tags":[]},{"url":"https://github.com/phpmyadmin/phpmyadmin/commit/b2a3e41f1e9ce42d1ee3f07a91f476029987799f","tags":[]},{"url":"https://github.com/phpmyadmin/phpmyadmin/pull/19087","tags":[]},{"url":"https://www.vulncheck.com/advisories/phpmyadmin-through-5.2.3-two-factor-authentication-removal-via-config-set","tags":[]}],"exploitRefs":[{"url":"https://github.com/phpmyadmin/phpmyadmin","tags":[]},{"url":"https://github.com/phpmyadmin/phpmyadmin/blob/RELEASE_5_2_3/libraries/classes/Controllers/Config/SetConfigController.php#L29-L41","tags":[]},{"url":"https://github.com/phpmyadmin/phpmyadmin/commit/6482dfa28bd56d515f482b008b194a516646fe1b","tags":[]},{"url":"https://github.com/phpmyadmin/phpmyadmin/commit/b2a3e41f1e9ce42d1ee3f07a91f476029987799f","tags":[]},{"url":"https://github.com/phpmyadmin/phpmyadmin/pull/19087","tags":[]}],"hasPoc":true,"ai":null}
