CVSS:3.0/AV:N/AC:L/PR:N/UI:N/S:U/C:H/I:H/A:H

An issue was discovered on Tenda AC7 devices with firmware through V15.03.06.44CN(AC7), AC9 devices with firmware through V15.03.05.19(6318)CN(AC9), and AC10 devices with firmware through V15.03.06.23CN(AC10). A command Injection vulnerability allows attackers to execute arbitrary OS commands via a crafted goform/setUsbUnload request. This occurs because the "formsetUsbUnload" function executes a dosystemCmd function with untrusted input.

Risk 86
Severity
9.8
Buffer Overflow
CVSS:3.0/AV:N/AC:L/PR:N/UI:N/S:U/C:H/I:H/A:H

An issue was discovered on Tenda AC7 V15.03.06.44CN, AC9 V15.03.05.19(6318)CN, AC10 V15.03.06.23CN, AC15 V15.03.05.19CN, and AC18 V15.03.05.19(6318)CN devices. There is a heap-based buffer overflow vulnerability in the router's web server -- httpd. While processing the 'mac' parameter for a post request, the value is directly used in a strcpy to a variable placed on the heap, which can leak sensitive information or even hijack program control flow.
