Operationally, exploitation aligns with the MITRE ATT&CK technique Command and Scripting Interpreter (T1059); ranked in the top 18% of CVEs by exploit likelihood; it is not currently listed in the CISA KEV catalog; a public proof-of-concept is referenced.

Deeper analysis AI-assisted summary

Synthesised by an AI model from the NVD description and linked references — a reading aid, not an authoritative source.

Motorola CX2L Router version 1.0.1 contains a command injection vulnerability, tracked as CVE-2023-31530 and assigned CWE-77, that affects the smartqos_priority_devices parameter. The flaw received a CVSS 3.1 score of 8.8, reflecting network attack vector, low attack complexity, and low required privileges without user interaction, resulting in high impact to confidentiality, integrity, and availability.

An authenticated attacker with network access can supply crafted input to the affected parameter and execute arbitrary commands on the device, enabling full compromise of the router's configuration and traffic handling.

The two provided references point to the same public GitHub repository containing proof-of-concept material for the issue, but contain no vendor advisory, patch information, or mitigation guidance. The associated EPSS score has remained flat at 0.1187 with no material increase since disclosure.

prevents

Secure architecture principles reduce the attack surface but do not prescribe the specific neutralization techniques needed.
