Attackers can submit a serialized gadget chain, such as one generated via phpggc, through the admin settings form (for example the maintenance_message setting loaded by CheckMaintenance.php) to achieve arbitrary operating-system command execution as the PHP application process user, with the impact persisting until the value is overwritten.","cvssScore":7.2,"cvssSeverity":"HIGH","cvssVector":"CVSS:3.1/AV:N/AC:L/PR:H/UI:N/S:U/C:H/I:H/A:H","cwes":["CWE-502"],"vendors":[],"products":[],"references":[{"url":"https://github.com/tastyigniter/TastyIgniter/issues/1205#issuecomment-6314187869","tags":[]},{"url":"https://www.vulncheck.com/advisories/tastyigniter-php-object-injection-via-settings-deserialization","tags":[]}],"exploitRefs":[{"url":"https://github.com/tastyigniter/TastyIgniter/issues/1205#issuecomment-6314187869","tags":[]}],"hasPoc":true,"ai":null}
