url //css//..%2f..%2f..%2f..%2f..%2f..%2f..%2f..%2f..%2f..%2f..%2f..%2f..%2f..%2f..%2f..%2f..%2f..%2fwindows\win.ini↗

path /css//..%2f↗

• → Look for HTTP requests where the URI begins with /css//..%2f — this is the specific traversal prefix used to exploit CVE-2018-7467 on AxxonSoft Axxon Next. ↗
• → Match response body for all three strings 'bit app support', 'fonts', and 'extensions' simultaneously (AND condition) to confirm successful windows\win.ini file read via directory traversal. ↗
• → The exploit uses percent-encoded forward slashes (%2f) in a double-slash path (/css//) to bypass path normalization; monitor for URL-encoded traversal sequences following this specific prefix. ↗

• · The Nuclei template requires 'unsafe: true' mode, meaning standard HTTP clients that normalize URLs will not reproduce the traversal — detection must account for raw/un-normalized request paths. ↗
