Vulnerability from variot - Updated: 2025-11-19 23:21

A flaw has been found in Tenda CH22 1.0.0.1. Affected by this issue is the function fromNatStaticSetting of the file /goform/NatStaticSetting. Executing manipulation of the argument page can lead to buffer overflow. It is possible to launch the attack remotely. The exploit has been published and may be used. The Tenda CH22 is a network device manufactured by Tenda, a Chinese company.

Version 1.0.0.1 of the Tenda CH22 contains a buffer overflow vulnerability. This vulnerability stems from the fact that the page parameter of the function fromNatStaticSetting in the file /goform/NatStaticSetting fails to properly validate the length of the input data. Attackers could exploit this vulnerability to execute arbitrary code on the system or cause a denial-of-service attack

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.
