regex: root:[x*]:0:0

• → Detect LFI exploitation attempts targeting CuppaCMS by monitoring POST requests to /alerts/alertConfigField.php with the 'urlConfig' parameter containing path traversal sequences (e.g., '../'). ↗
• → A successful exploitation response will return HTTP 200 and contain the string matching 'root:[x*]:0:0' in the body, indicating /etc/passwd was read. ↗
• → The vulnerable parameter is 'urlConfig' submitted via application/x-www-form-urlencoded in a POST body to the alertConfigField.php endpoint. ↗

• · The vulnerability is confirmed only in CuppaCMS v1.0 (cpe:2.3:a:cuppacms:cuppacms:1.0). Detections should be scoped to this version to reduce false positives. ↗
• · CVSS vector is AV:L (local attack vector) per NVD classification, but the Nuclei template exploits it over HTTP POST, suggesting network-accessible deployments are also at risk. ↗
