IIS 5 and 5.1 supporting WebDAV methods allows remote attackers to determine the internal IP address of the system (which may be obscured by NAT) via (1) a PROPFIND HTTP request with a blank Host header, which leaks the address in an HREF property in a 207 Multi-Status response, or (2) via the WRITE or MKCOL method, which leaks the IP in the Location server header.
CVE-2002-0422
This CVE was only ever scored under CVSS v2.0. NVD CVSS v2.0 base 2.6 — v2 rates that LOW (v2 bands: LOW 0.0–3.9 / MEDIUM 4.0–6.9 / HIGH 7.0–10.0; v2 has no CRITICAL band). Vector AV:N/AC:H/Au:N/C:P/I:N/A:N. CVSS v2 is an older, coarser metric than v3.1/v4.0 (no Scope, no User Interaction, no Attack Requirements), so it is not directly comparable to a v3 or v4 score. NVD has never re-scored this record under v3. EPSS predicts 42.3% exploitation probability in the next 30 days, which is reflected in EG Risk but does not lift the v2 base. Confidence: LOW.
- Lower severity and no public exploit yet
No vendor fix yet — apply a workaround or compensating control (WAF / firewall / segmentation) and watch for a patch.

EG Risk is EchelonGraph's 0–100 priority score: it fuses intrinsic severity with real-world exploitation and automatability so you can rank equal-severity CVEs and fix the most dangerous first. Higher = act sooner. Distinct from the 0–10 EG Score (severity).
