Stack-based buffer overflow in nsum.exe in the Windows Media Unicast Service in Media Services for Microsoft Windows 2000 Server SP4 allows remote attackers to execute arbitrary code via crafted packets associated with transport information, aka "Media Services Stack-based Buffer Overflow Vulnerability."
CVE-2010-0478
This CVE was only ever scored under CVSS v2.0. NVD CVSS v2.0 base 9.3 — v2 rates that HIGH (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:M/Au:N/C:C/I:C/A:C. 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 60.4% exploitation probability in the next 30 days, which is reflected in EG Risk but does not lift the v2 base. Confidence: LOW.
- High exploitation likelihood — EPSS 60%
- Public exploit code is available (Metasploit, Exploit-DB (verified), epss top5pct, epss high, public exploit)
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).
