VAR-202209-1579

Vulnerability from variot - Updated: 2025-05-23 23:19

Tenda W20E router V15.11.0.6 contains a stack overflow in the function formSetPortMapping with post request 'goform/setPortMapping/'. This vulnerability allows attackers to cause a Denial of Service (DoS) or Remote Code Execution (RCE) via the portMappingServer, portMappingProtocol, portMappingWan, porMappingtInternal, and portMappingExternal parameters. Shenzhen Tenda Technology Co.,Ltd. of W20E An out-of-bounds write vulnerability exists in firmware.Information is obtained, information is tampered with, and service operation is interrupted. (DoS) It may be in a state. The vulnerability is due to the fact that the formSetPortMapping method does not check the size of the input data when it has a POST request goform/setPortMapping/
