Vulnerability from variot - Updated: 2025-11-19 23:27

Totolink LR350 v9.3.5u.6369_B20220309 was discovered to contain a stack overflow via the wifiOff parameter in the sub_4232EC function. This vulnerability allows attackers to cause a Denial of Service (DoS) via a crafted request. The TOTOLINK LR350 is a 4G LTE wireless router launched by TOTOLINK Electronics, a Chinese company. It supports converting 4G signals to wired signals and is suitable for home and office use. This vulnerability stems from the fact that the wifiOff parameter in the sub_4232EC function fails to properly validate the length of the input data

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.
