Description
A buffer overflow issue exists in the router's web server, specifically in the httpd. The problem arises when the
firewallEn parameter is processed for a post request. The value of this parameter is directly used in a strcpy to a local variable on the stack, which overrides the return address of the function.Recommendations
For Tenda AC7 version 15.03.06.44 CN, avoid using the
firewallEn parameter in post requests until a patch is available.
For Tenda AC9 version 15.03.05.19(6318) CN, restrict access to the httpd web server to minimize the risk of exploitation.
For Tenda AC10 version 15.03.06.23 CN, consider disabling the httpd service temporarily until a fix is provided.
For Tenda AC15 version 15.03.05.19 CN, refrain from using the vulnerable httpd web server until an update is released.
For Tenda AC18 version 15.03.05.19(6318) CN, as a temporary workaround, limit the use of the firewallEn parameter in post requests to prevent potential exploitation.Exploit
