url {{BaseURL}}/img/../../../../../../etc/passwd↗

• → Send an HTTP GET request to the path /img/../../../../../../etc/passwd to test for directory traversal (LFI) in the Clustering application. A successful exploit returns /etc/passwd content in the response body. ↗
• → Match the response body for the regex pattern 'root:.*:0:0:' to confirm successful local file inclusion and /etc/passwd disclosure. ↗
• → The vulnerability exists in the Clustering project at commit 53e663e259bcfc8cdecb56c0bb255bd70bfcaa70; target instances running this specific commit or earlier. ↗

• · The traversal payload uses /img/ as the entry point; other endpoints may not be vulnerable. Confirm the target is running the Clustering application before testing. ↗
• · Only one HTTP request is needed to confirm exploitation (max-request: 1), making this a low-noise, single-probe check. ↗
