Moxa EDR-G903

Certain Moxa Inc products are affected by an improper restriction of operations in EDR-G903 Series Firmware Version 5.5 or lower, EDR-G902 Series Firmware Version 5.5 or lower, and EDR-810 Series Firmware Version 5.6 or lower. Crafted requests sent to the device may allow remote arbitrary code execution.

Malicious operation of the crafted web browser cookie may cause a stack-based buffer overflow in the system web server on the EDR-G902 and EDR-G903 Series Routers (versions prior to 5.4).

Moxa Secure Router EDR-G903 devices before 3.4.12 do not delete copies of configuration and log files after completing the import function, which allows remote attackers to obtain sensitive information by requesting these files at an unspecified URL.

Memory leak on Moxa Secure Router EDR-G903 devices before 3.4.12 allows remote attackers to cause a denial of service (memory consumption) by executing the ping function.

Moxa Secure Router EDR-G903 devices before 3.4.12 allow remote attackers to cause a denial of service (cold start) by sending two crafted ping requests.

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.

Moxa Secure Router EDR-G903 devices before 3.4.12 allow remote attackers to read configuration and log files via a crafted URL.

Moxa Secure Router EDR-G903 devices before 3.4.12 allow remote attackers to discover cleartext passwords by reading a configuration file.

Web Server Buffer Overflow Vulnerability

Moxa EDR-G903 series routers with firmware before 2.11 have a hardcoded account, which allows remote attackers to obtain unspecified device access via unknown vectors.
