VAR-202404-0368

Vulnerability from variot - Updated: 2024-06-06 23:01

A vulnerability, which was classified as critical, was found in Tenda W15E 15.11.0.14. Affected is the function formAddDnsForward of the file /goform/AddDnsForward. The manipulation of the argument DnsForwardRule leads to stack-based buffer overflow. It is possible to launch the attack remotely. The exploit has been disclosed to the public and may be used. VDB-261858 is the identifier assigned to this vulnerability. NOTE: The vendor was contacted early about this disclosure but did not respond in any way. W15E is a wireless router from China's Tenda Company.

Shenzhen Jixiang Tenda Technology Co., Ltd. The vulnerability is caused by the DnsForwardRule parameter of the formAddDnsForward method of the /goform/AddDnsForward file failing to correctly verify the length of the input data. Remote attackers can exploit this vulnerability to execute arbitrary code on the system or cause a denial of service attack

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.
