CVE-2012-1846

HIGHCVSS v2 · 10.010.0—
EchelonGraph scoreLOW confidence

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 3.7% exploitation probability in the next 30 days, which is reflected in EG Risk but does not lift the v2 base. Confidence: LOW.

Google Chrome 17.0.963.66 and earlier allows remote attackers to bypass the sandbox protection mechanism by leveraging access to a sandboxed process, as demonstrated by VUPEN during a Pwn2Own competition at CanSecWest 2012. NOTE: the primary affected product may be clarified later; it was not identified by the researcher, who reportedly stated "it really doesn't matter if it's third-party code."
