Tenda AX3 V16.03.12.10CN was discovered to contain a stack overflow in the deviceId parameter of the saveParentControlInfo function. This vulnerability allows attackers to cause a Denial of Service (DoS) via a crafted request.

Tenda AX3 V16.03.12.10CN was discovered to contain a stack overflow in the urls parameter of the getparentControllistInfo function. This vulnerability allows attackers to cause a Denial of Service (DoS) via a crafted request.

Tenda AX-3 v16.03.12.10CN was discovered to contain a stack overflow via the shareSpeed parameter in the fromSetWifiGusetBasic function. This vulnerability allows attackers to cause a Denial of Service (DoS) via a crafted request.

Tenda AX3 V16.03.12.10CN was discovered to contain a stack overflow in the wpapskcrypto parameter of the wlSetExternParameter function. This vulnerability allows attackers to cause a Denial of Service (DoS) via a crafted request.

There is a stack buffer overflow vulnerability in the formSetPPTPServer function of Tenda-AX3 router V16.03.12.10CN. The v13 variable is directly retrieved from the http request parameter startIp. Then v13 will be splice to stack by function sscanf without any security check, which causes stack overflow. By POSTing the page /goform/SetPptpServerCfg with proper startIp, the attacker can easily perform remote code execution with carefully crafted overflow data.
