The management console in Symantec Web Gateway 5.0.x before 5.0.3.18 allows remote attackers to execute arbitrary commands via crafted input to application scripts.
CVE-2012-2953
This CVE was only ever scored under CVSS v2.0. NVD CVSS v2.0 base 10.0 — 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:L/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 67.4% 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 67%
- 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).
