Description
A buffer overflow issue exists in the router's web server, specifically in the httpd. The problem arises when processing the
startIp and endIp parameters for a post request. Each value is directly used in a sprintf to a local variable placed 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 addresses the buffer overflow vulnerability in the httpd web server.
For Tenda AC9 version 15.03.05.19(6318) CN, update the firmware to a version that addresses the buffer overflow vulnerability in the httpd web server.
For Tenda AC10 version 15.03.06.23 CN, update the firmware to a version that addresses the buffer overflow vulnerability in the httpd web server.
For Tenda AC15 version 15.03.05.19 CN, update the firmware to a version that addresses the buffer overflow vulnerability in the httpd web server.
For Tenda AC18 version 15.03.05.19(6318) CN, update the firmware to a version that addresses the buffer overflow vulnerability in the httpd web server.
As a temporary workaround, consider restricting access to the httpd web server until a patch is available. Avoid using the
startIp and endIp parameters in post requests to the vulnerable web server until the issue is resolved.Exploit
