Vulnerability from variot - Updated: 2025-08-09 23:04

TOTOLINK LR350 V9.3.5u.6369_B20220309 was discovered to contain a stack overflow via the password parameter in the function urldecode. TOTOLINK of lr350 A stack-based buffer overflow vulnerability exists in the firmware.Information is obtained, information is tampered with, and service operation is interrupted. (DoS) It may be in a state. The TOTOLINK LR350 is a 4G LTE router released by China's TOTOLINK Electronics. It converts 4G signals into wired signals and is suitable for home and office use.

The TOTOLINK LR350 suffers from a buffer overflow vulnerability. This vulnerability stems from the failure of the password parameter in the urldecode function to properly validate the length of the input data. An attacker could exploit this vulnerability to execute arbitrary code on the system or cause a denial of service

(DoS) It may be in a state. The TOTOLINK LR350 is a 4G LTE router released by China\u0027s TOTOLINK Electronics. It converts 4G signals into wired signals and is suitable for home and office use. \n\nThe TOTOLINK LR350 suffers from a buffer overflow vulnerability. This vulnerability stems from the failure of the password parameter in the urldecode function to properly validate the length of the input data. An attacker could 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.
