→Detect directory traversal attempts using mixed forward/backslash sequences (/..\ patterns) in HTTP GET requests targeting Windows file paths such as win.ini. ↗
→Confirm successful exploitation by checking HTTP response body for all three strings: 'bit app support', 'fonts', and 'extensions' (contents of windows\win.ini). ↗
→The traversal payload uses backslash characters after the initial forward slash, characteristic of Windows-targeted path traversal on the Acrolinx Server dashboard endpoint. ↗

·The exploit requires sending a raw HTTP request with unsafe characters (backslashes in URL path); standard HTTP clients may normalize or reject the payload before it reaches the server. ↗
·Vulnerability is Windows-specific; the traversal relies on Windows path separator handling and targets Windows system files. ↗
