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.\n\n## Affected\n\n- `TastyIgniter <= 4.4.5`\n\n## Remediation\n\nRefer to the linked advisories for vendor-supplied fixes and affected version ranges.","depth":"twilight","depthScore":40,"depthScoreParts":{"impact":39.6,"likelihood":0,"exploitation":0,"ransomware":0},"changes":[]}
