The firmware of EDIMAX IC-3140W Version 3.11 is hardcoded with Administrator username and password.
A stack-based buffer-overflow exists in Edimax IP-Camera IC-3116W (v3.06) and IC-3140W (v3.07), which allows an unauthenticated, unauthorized attacker to perform remote-code-execution due to a crafted GET-Request. The overflow occurs in binary ipcamcgi due to a missing type check in function doGetSysteminfo(). This has been fixed in version: IC-3116W v3.08.
An issue was discovered on EDIMAX IC-3140W through 3.06, IC-5150W through 3.09, and IC-6220DC through 3.06 devices. The ipcamcgi binary contains a stack-based buffer overflow that is possible to trigger from a remote unauthenticated /camera-cgi/public/getsysyeminfo.cgi?action=VALUEHERE HTTP request: if the VALUEHERE length is more than 0x400 (1024), it is possible to overwrite other values located on the stack due to an incorrect use of the strcpy() function.
The default administrator account & password of the EDIMAX wireless network camera is hard-coded. Remote attackers can disassemble firmware to obtain the privileged permission and further control the devices.
