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/formWlanRedirect of the component HTTP POST Request Handler. The manipulation of the argument redirect-url 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 remote code execution vulnerability affecting TOTOLIK EX1200T wireless routers has been publicly disclosed with working exploit code available. Organizations using this router model are immediately at risk of unauthorized device compromise, network infiltration, and potential lateral movement into corporate networks.
- Network segmentation: Restrict access to router management interface to authorized IP ranges only. 2) WAF/IDS rules: Block HTTP POST requests to /boafrm/formWlanRedirect endpoint; inspect redirect-url parameters for buffer overflow patterns. 3) Disable feature: Disable the WLAN redirect feature if operationally feasible. 4) Access controls: Restrict network access to affected devices; disable remote management. 5) Monitor: Enable enhanced logging on router access and authentication attempts. 6) Monitor vendor for emergency security patch.

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.
