DescriptionCVE.org

A vulnerability has been found in TOTOLINK EX1200T 4.1.2cu.5232_B20210713 and classified as critical. Affected by this vulnerability is an unknown functionality of the file /boafrm/formMultiAP of the component HTTP POST Request Handler. The manipulation of the argument submit-url leads to buffer overflow. The attack can be launched remotely. The exploit has been disclosed to the public and may be used.

Executive ViewAI

Why It Matters

A critical remote buffer overflow vulnerability (CVE-2025-6162) affects TOTOLIK EX1200T routers with publicly available exploit code. Organizations using this device model are at immediate risk of unauthorized access and network compromise, with no vendor patch currently available.

Business Impact: Severe

Compensating Controls

Implement Web Application Firewall (WAF) rules to block or sanitize POST requests to /boafrm/formMultiAP endpoint with oversized submit-url parameters; disable HTTP management interface if not required and restrict access via network segmentation; apply rate limiting on affected endpoint; monitor for exploitation attempts; consider disabling the multi-AP functionality if unused.

Attack Technique

Buffer Overflow HIGH

A buffer overflow occurs when a program writes more data to a memory buffer than it was allocated to hold, causing the excess data to spill into adjacent memory regions.

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.
