Deeper analysis

Motorola CX2L Router version 1.0.1 contains a command injection vulnerability in the staticroute_list parameter, classified under CWE-77. The flaw received a CVSS 3.1 score of 8.8, reflecting network attack vector, low attack complexity, and requirements for authenticated access without user interaction, resulting in high impact across confidentiality, integrity, and availability.

An authenticated attacker with network access can supply crafted values to the staticroute_list parameter, enabling arbitrary command execution on the device. Successful exploitation grants the ability to read, modify, or delete data and potentially take full control of the router.

Public references consist of two GitHub repositories that document the issue and provide reproduction details. The associated EPSS score remains flat at 0.1187 with no observed increase since disclosure.
