CRITICAL 9.8

DescriptionCVE.org

EDIMAX BR-6208AC V2_1.02 is vulnerable to Command Injection. This arises because the pppUserName field is directly passed to a shell command via the system() function without proper sanitization. An attacker can exploit this by injecting malicious commands into the pppUserName field, allowing arbitrary code execution.

Executive ViewAI

Why It Matters

Organizations using EDIMAX BR-6208AC V2_1.02 face critical risk from CVE-2025-70161, a command injection vulnerability rated CVSS 9.8. Successful exploitation could allow attackers to execute arbitrary code or commands on affected systems, potentially leading to full system compromise. Proof-of-concept code is publicly available, increasing the risk of exploitation. Organizations should apply vendor updates immediately when available and implement compensating controls in the interim.

Business Impact: Severe

Compensating Controls

Apply vendor patch. If immediate patching is not feasible: (1) Deploy WAF rules to block injection patterns; (2) Restrict network access to affected components; (3) Enable enhanced logging for suspicious activity.
