url {{BaseURL}}/webmail/?language=%22%3E%3Cimg%20src%3Dx%20onerror%3Dalert(1)%3E↗

path /webmail/↗

• → Look for GET requests to /webmail/ with a `language` parameter containing an XSS payload such as URL-encoded `"><img src=x onerror=alert(1)>` ↗
• → Identify exposed IceWarp WebMail instances via Shodan/FOFA using title-based queries for 'icewarp' or 'icewarp server administration' ↗

• · The XSS payload is injected via the `language` GET parameter and reflected in the response body; the vulnerable endpoint is /webmail/ on IceWarp WebMail version 11.4.5.0 specifically ↗
• · No authentication is required (PR:N) and user interaction is required (UI:R), meaning the attack is delivered to a victim via a crafted link ↗
