CVE-2026-3729
Plain English Summary
AI-powered analysis for quick understanding
An attacker can remotely take control of the Tenda F453 router by exploiting a flaw in its firmware that allows them to overflow a memory area, potentially leading to unauthorized access or execution of malicious code. This vulnerability can be triggered by manipulating specific input fields, making it easy for attackers to exploit if they know how to send the right data.
Technical Description
A vulnerability was identified in Tenda F453 1.0.0.3/3.As. Impacted is the function fromPptpUserAdd of the file /goform/PPTPDClient. Such manipulation of the argument username/opttype leads to stack-based buffer overflow. The attack can be executed remotely. The exploit is publicly available and might be used.
