Vulnerability from variot - Updated: 2025-06-15 23:46

A vulnerability, which was classified as critical, was found in TOTOLINK EX1200T 4.1.2cu.5232_B20210713. Affected is an unknown function of the file /boafrm/formPortFw of the component HTTP POST Request Handler. The manipulation of the argument service_type leads to buffer overflow. It is possible to launch the attack remotely. The exploit has been disclosed to the public and may be used. TOTOLINK of ex1200t The firmware contains a buffer error vulnerability and a classic buffer overflow vulnerability.Service operation interruption (DoS) It may be in a state. TOTOLINK EX1200T is a Wi-Fi range extender from China's TOTOLINK Electronics. The vulnerability is caused by the parameter service_type in the file /boafrm/formPortFw failing to properly verify the length of the input data. Attackers can exploit this vulnerability to execute arbitrary code on the system or cause a denial of service

The MITRE ATT&CK techniques below are AI-generated suggestions, inferred from the description of the vulnerability by the CIRCL/vulnerability-attack-technique-classification-roberta-base model, served locally by ML-Gateway. They have not been verified by an analyst and are provided for guidance only.
The approach is described in our paper Mapping CVEs to MITRE ATT&CK Techniques: A Curated Gold-Set Classifier and the Limits of LLM-Assisted Label Expansion.
