path /index.php?option=com_jtagmembersdirectory&task=attachment&download_file=[FILE]↗

• → Detect LFI exploitation attempts targeting the Jtag Members Directory component by matching the Joomla component option and task parameters in HTTP GET requests. ↗
• → Alert on HTTP 200 responses to requests containing 'com_jtagmembersdirectory' and 'download_file' with path traversal sequences, especially when the response body matches the pattern 'root:.*:0:0:' indicating /etc/passwd disclosure. ↗

• · The vulnerability is exploited via the 'download_file' parameter in the Jtag Members Directory component (com_jtagmembersdirectory). The attacker-controlled parameter is passed directly without sanitization, enabling path traversal to arbitrary files. ↗
• · The exploit requires no authentication (PR:N, UI:N per CVSS), meaning any unauthenticated remote attacker can trigger the file download. ↗
