Plain English Summary
AI-powered analysis for quick understanding
This vulnerability allows an attacker to remotely execute code on Tenda A18 routers by exploiting a flaw in the file upload function, which can lead to a stack-based buffer overflow. To successfully carry out the attack, the attacker needs to manipulate specific input parameters, and there are already publicly available methods to exploit this weakness.
Technical Description
A vulnerability was identified in Tenda A18 15.13.07.13. The affected element is the function webCgiGetUploadFile of the file /cgi-bin/UploadCfg of the component Httpd Service. Such manipulation of the argument boundary leads to stack-based buffer overflow. The attack can be executed remotely. The exploit is publicly available and might be used.
