HIGH 8.8

DescriptionCVE.org

A vulnerability classified as critical has been found in TOTOLINK EX1200T 4.1.2cu.5232_B20210713. Affected is an unknown function of the file /boafrm/formIpv6Setup of the component HTTP POST Request Handler. The manipulation of the argument submit-url leads to buffer overflow. It is possible to launch the attack remotely. The exploit has been disclosed to the public and may be used.

Executive ViewAI

Why It Matters

A critical buffer overflow vulnerability in TOTOLIK EX1200T routers allows remote attackers to execute arbitrary code without authentication. Organizations using this device model are at immediate risk of network compromise, data theft, and potential lateral movement into corporate systems, especially if these routers serve as network gateways or access points.

Business Impact: High

Compensating Controls

Implement WAF rules to block HTTP POST requests to /boafrm/formIpv6Setup endpoint; disable IPv6 setup functionality if not required; segment routers behind a firewall with restricted internet exposure; disable remote management interfaces; enforce strong network access controls limiting device accessibility to authorized networks only; increase monitoring and alerting for suspicious traffic patterns targeting the vulnerable endpoint.

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.
