Vulnerability from variot - Updated: 2025-09-18 23:12

Tenda AC6 US_AC6V1.0BR_V15.03.05.16_multi_TD01.bin is vulnerable to Buffer Overflow via function "fromGetWirelessRepeat.". The Tenda AC6 is a dual-band wireless router from Tenda. It supports both 2.4GHz and 5GHz bands, boasts a maximum transmission rate of 1167Mbps, and features dual-band integration.

The Tenda AC6 suffers from a buffer overflow vulnerability caused by the fromGetWirelessRepeat function's failure to properly validate the length of input data. An attacker could exploit this vulnerability to execute arbitrary code or cause a denial of service

Detection rules are retrieved from Rulezet.

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.
