CVE-2014-4936

HIGHCVSS v2 · 9.39.3—
EchelonGraph scoreLOW confidence

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 16.8% exploitation probability in the next 30 days, which is reflected in EG Risk but does not lift the v2 base. Confidence: LOW.

The upgrade functionality in Malwarebytes Anti-Malware (MBAM) consumer before 2.0.3 and Malwarebytes Anti-Exploit (MBAE) consumer 1.04.1.1012 and earlier allow man-in-the-middle attackers to execute arbitrary code by spoofing the update server and uploading an executable.
