Lifecycle Timeline
2DescriptionCVE.org
A vulnerability, which was classified as critical, has been found in TOTOLINK EX1200T 4.1.2cu.5232_B20210713. This issue affects some unknown processing of the file /boafrm/formStats of the component HTTP POST Request Handler. The manipulation leads to buffer overflow. The attack may be initiated remotely. The exploit has been disclosed to the public and may be used.
Executive ViewAI
A critical buffer overflow vulnerability affecting TOTOLIK EX1200T routers allows remote attackers to execute arbitrary code without authentication. Organizations using this router model face immediate risk of network compromise, data theft, and potential lateral movement into critical systems, especially since a public exploit exists and no patch is currently available.
Implement network access controls restricting administrative interfaces to trusted IP ranges only; deploy WAF or IPS rules to block malicious POST payloads to /boafrm/formStats endpoint; disable HTTP management interface if HTTPS alternative is available; segment router management traffic from production networks; enable comprehensive logging and alerting for any access attempts to the vulnerable endpoint; consider implementing a reverse proxy with input validation in front of the device.

How this decision was reached
The engine reads each signal below and applies a fixed list of rules from top to bottom. The first rule that matches sets the recommended action – like a statement, every line is shown.
What every action level means
SSVC AssessmentENISA
Priority Score
Attack Technique
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 represents the critical moment when an attacker successfully runs arbitrary code on a target system without physical access.
