Description
A buffer overflow issue exists in the router's web server, specifically in the
httpd component. This occurs when the page parameter of the fromAddressNat function is processed for a post request. The value is directly used in a sprintf 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, update the firmware to a version that fixes the buffer overflow vulnerability in the
httpd component.
For Tenda AC9 version 15.03.05.19(6318) CN, update the firmware to a version that fixes the buffer overflow vulnerability in the httpd component.
For Tenda AC10 version 15.03.06.23 CN, update the firmware to a version that fixes the buffer overflow vulnerability in the httpd component.
For Tenda AC15 version 15.03.05.19 CN, update the firmware to a version that fixes the buffer overflow vulnerability in the httpd component.
For Tenda AC18 version 15.03.05.19(6318) CN, update the firmware to a version that fixes the buffer overflow vulnerability in the httpd component.
As a temporary workaround, consider restricting access to the fromAddressNat function until a patch is available. Avoid using the page parameter in the affected post request until the issue is resolved.Exploit
