DescriptionCVE.org

Tenda AX3 firmware v16.03.12.11 contains a stack overflow in formGetIptv function and the list parameter, which can cause memory corruption and enable remote code execution.

Executive ViewAI

Why It Matters

Tenda AX3 routers running firmware v16.03.12.11 are vulnerable to remote code execution through a stack overflow vulnerability, allowing unauthenticated attackers to gain full control of affected devices. Organizations using this equipment for network connectivity face immediate risk of network compromise, data exfiltration, and lateral movement into corporate systems.

Business Impact: High

Compensating Controls

Implement network segmentation to isolate affected devices; disable remote management interfaces via firewall rules; restrict WAN access to the device's web interface (port 80/443); monitor for exploitation attempts targeting the formGetIptv function; consider replacing with alternative vendor equipment until patch is available; disable IPTV feature if not in use. Deploy WAF rules to block malformed list parameter payloads if device is internet-facing.

Attack Technique

Stack-based Buffer Overflow HIGH

A stack-based buffer overflow occurs when a program writes more data to a buffer located on the stack than it was allocated to hold.

Memory Corruption HIGH

Memory corruption occurs when a program writes data beyond the boundaries of allocated memory regions or accesses memory in unintended ways, violating the integrity of the process's address space.

Remote Code Execution CRITICAL

Remote Code Execution represents the critical moment when an attacker successfully runs arbitrary code on a target system without physical access.
