The supplied Nuclei template performs passive version detection: it sends a
GET /request and checks theServerheader for a vulnerable Serv-U version. It does not include the crafted POST request or payload described in the vulnerability text. The rule therefore uses the only stated request-side attack indicator,Content-Encoding: deflate, and the test sends that header on a POST request.No URI condition is included because the template does not identify a vulnerable endpoint. This header-only signature may also match legitimate deflate-encoded requests; the available input does not provide enough detail to narrow it safely to a specific path or payload. The classification retains the required CVE, attack, and CWE entries.
