Technical analysis, exploit verification, and patch instructions for CVE-2012-4694 impacting moxa edr_g903_firmware. Evaluated with CVSS Base Score of 7.6 (UNKNOWN).

Original NVD Description

Source: NIST NVD
Moxa EDR-G903 series routers with firmware before 2.11 do not use a sufficient source of entropy for (1) SSH and (2) SSL keys, which makes it easier for man-in-the-middle attackers to spoof a device or modify a client-server data stream by leveraging knowledge of a key from a product installation elsewhere.
