url /fw.progrss.details.php?popup=..%2f..%2f..%2f..%2f..%2f..%2fetc%2fpasswd↗

path /fw.progrss.details.php↗

• → Look for GET requests to /fw.progrss.details.php with a 'popup' parameter containing path traversal sequences (e.g., ..%2f or ../) targeting /etc/passwd or other sensitive files. ↗
• → A successful exploitation response will return HTTP 200 and contain the string matching 'root:[x*]:0:0' in the body, indicating /etc/passwd file disclosure. ↗
• → Shodan and FOFA can be used to identify exposed Artica Proxy instances via the fingerprints 'http.html:"artica"' and 'body="artica"' respectively. ↗

• · The vulnerability is unauthenticated (PR:N, UI:N), meaning no credentials are required to exploit the LFI via the popup parameter. ↗
• · Only Artica Proxy Community Edition versions before 4.30.000000 are affected; the fix is to upgrade to 4.30.000000 or later. ↗
