- →Monitor for GET requests to the path /SAAS/t/_/;/WEB-INF/web.xml — the semicolon path traversal segment is the key exploit indicator for the authentication bypass leading to LFI of web.xml. ↗
- →Monitor for POST requests where the URI starts with /SAAS/t/ and ends with /auth/login/embeddedauthbroker/callback with Content-Type: application/x-www-form-urlencoded (exactly 33 bytes) — this is the auth endpoint abused to obtain the HZN session cookie. ↗
- →The Nuclei template matcher confirms exploitation by checking the response body for the XML servlet-mapping tag and Content-Type header of application/xml with HTTP 200 — use these as response-side detection signals. ↗
- ·The FOFA query targets VMware Workspace ONE Access, Identity Manager, and vRealize Automation by favicon hash and app fingerprint — ensure these queries are scoped to your asset inventory to avoid false positives. ↗
- ·The ET SNORT rule (sid:2038475) uses a strict bsize:33 match on the Content-Type header — any variation in content-type length by an attacker could evade this specific rule; supplement with path-based detection. ↗
