The setter.xml component of the Common Gateway Interface on Compal CH7465LG 6.12.18.25-2p4 devices does not properly validate ping command arguments, which allows remote authenticated users to execute OS commands as root via shell metacharacters in the Target_IP parameter.

The web interface of the Compal Broadband CH7465LG modem (version CH7465LG-NCIP-6.12.18.25-2p6-NOSH) is vulnerable to a /%2f/ path traversal attack, which can be exploited in order to test for the existence of a file pathname outside of the web root directory. If a file exists but is not part of the product, there is a 404 error. If a file does not exist, there is a 302 redirect to index.html.

Compal CH7465LG CH7465LG-NCIP-6.12.18.24-5p8-NOSH devices have Incorrect Access Control because of Improper Input Validation. The attacker can send a maliciously modified POST (HTTP) request containing shell commands, which will be executed on the device, to an backend API endpoint of the cable modem.
