CVE-2010-0483

HIGHCVSS v2 · 7.67.6—
EchelonGraph scoreLOW confidence

This CVE was only ever scored under CVSS v2.0. NVD CVSS v2.0 base 7.6 — 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:H/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 86.4% exploitation probability in the next 30 days, which is reflected in EG Risk but does not lift the v2 base. Confidence: LOW.

vbscript.dll in VBScript 5.1, 5.6, 5.7, and 5.8 in Microsoft Windows 2000 SP4, XP SP2 and SP3, and Server 2003 SP2, when Internet Explorer is used, allows user-assisted remote attackers to execute arbitrary code by referencing a (1) local pathname, (2) UNC share pathname, or (3) WebDAV server with a crafted .hlp file in the fourth argument (aka helpfile argument) to the MsgBox function, leading to code execution involving winhlp32.exe when the F1 key is pressed, aka "VBScript Help Keypress Vulnerability."
