url/proxy?url=http://{{interactsh-url}}

path/proxy

→SSRF probe: HTTP GET request to the /proxy endpoint with a url= parameter pointing to an out-of-band callback host. A successful exploit returns HTTP 200 with Content-Type: application/octet-stream and triggers a DNS interaction.
→Shodan/FOFA fingerprint for exposed draw.io instances: search for html:"draw.io" (Shodan) or body="draw.io" (FOFA) to identify attack surface.
→The vulnerable component is the ProxyServlet; look for GET requests to /proxy?url= in web server access logs, especially where the url parameter resolves to internal RFC-1918 or link-local addresses.
→The fix introduces isLinkLocalAddress() checks; absence of this check in versions prior to 18.0.5 confirms exploitability. Reference the patch commit for diff-based detection. ↗

·Vulnerability is only present in draw.io (diagrams.net) versions strictly prior to 18.0.5; version 18.0.5 and later are patched. ↗
·The attack requires no authentication (PR:N, UI:N), meaning any network-reachable instance is exposed without credentials.
·Out-of-band DNS interaction (interactsh) is required to confirm exploitation; a 200 response alone is insufficient — Content-Type must also be application/octet-stream and a DNS callback must be observed.
