CVE-2014-9583

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 80.7% exploitation probability in the next 30 days, which is reflected in EG Risk but does not lift the v2 base. Confidence: LOW.

common.c in infosvr in ASUS WRT firmware 3.0.0.4.376_1071, 3.0.0.376.2524-g0013f52, and other versions, as used in RT-AC66U, RT-N66U, and other routers, does not properly check the MAC address for a request, which allows remote attackers to bypass authentication and execute arbitrary commands via a NET_CMD_ID_MANU_CMD packet to UDP port 9999. NOTE: this issue was incorrectly mapped to CVE-2014-10000, but that ID is invalid due to its use as an example of the 2014 CVE ID syntax change.
