VAR-202510-0163

Vulnerability from variot - Updated: 2025-10-20 00:16

A flaw has been found in Tenda AC7 15.03.06.44. This issue affects some unknown processing of the file /goform/SetDDNSCfg. This manipulation of the argument ddnsEn causes stack-based buffer overflow. The attack can be initiated remotely. The exploit has been published and may be used. The Tenda AC7 is a wireless router from the Chinese company Tenda. This vulnerability stems from the failure of the ddnsEn parameter in the /goform/SetDDNSCfg file to properly validate the length of 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.
