DescriptionCVE.org

A vulnerability was found in Tenda AC9 15.03.02.13. It has been rated as critical. This issue affects the function formSetIptv of the file /goform/SetIPTVCfg of the component POST Request Handler. The manipulation of the argument list leads to command injection. The attack may be initiated remotely. The exploit has been disclosed to the public and may be used.

AnalysisAI

Command injection in Tenda AC9 router firmware 15.03.02.13 allows remote authenticated attackers to execute arbitrary commands via the 'list' parameter in the formSetIptv handler. A public exploit is available, and EPSS score (2.05%, 84th percentile) indicates moderate exploitation likelihood, though no active exploitation in CISA KEV is reported.

Technical ContextAI

The vulnerability resides in the POST request handler for /goform/SetIPTVCfg, which processes IPTV configuration. The 'list' argument is not sanitized before being used in a system command, leading to OS command injection (CWE-74). The affected product is Tenda AC9 router firmware version 15.03.02.13, a consumer-grade wireless router. The CPE string cpe:2.3:o:tenda:ac9_firmware:15.03.2.13 confirms the exact firmware version.

RemediationAI

Upgrade to a patched firmware version if available; Tenda has not released a fix as of analysis. As a workaround, restrict access to the router's web interface to trusted networks only, disable remote management, and change default credentials. Monitor for vendor updates at https://www.tenda.com.cn/. Note that disabling IPTV functionality may mitigate the attack vector but could affect service.
