CVE-2026-3728

Plain English Summary

AI-powered analysis for quick understanding

An attacker can remotely exploit a vulnerability in the Tenda F453 router to execute arbitrary code by causing a stack-based buffer overflow through a specific function in its firmware. This means that if the attacker knows how to manipulate certain inputs, they can gain control over the router and potentially compromise the network it’s connected to.

Technical Description

A vulnerability was determined in Tenda F453 1.0.0.3/1.If. This issue affects the function fromSetCfm of the file /goform/setcfm. This manipulation of the argument funcname/funcpara1 causes stack-based buffer overflow. Remote exploitation of the attack is possible. The exploit has been publicly disclosed and may be utilized.
