Tenda » Ac15 Firmware : Security Vulnerabilities, CVEs,

The goform/setUsbUnload endpoint of Tenda AC15 AC1900 version 15.03.05.19 allows remote attackers to execute arbitrary system commands via the deviceName POST parameter.

A hard-coded telnet credential in the tenda_login binary of Tenda AC15 AC1900 version 15.03.05.19 allows unauthenticated remote attackers to start a telnetd service on the device.

goform/AdvSetLanip endpoint on Tenda AC15 AC1900 15.03.05.19 devices allows remote attackers to execute arbitrary system commands via shell metacharacters in the lanIp POST parameter.

An issue was discovered on Tenda AC9 V15.03.05.19(6318)_CN, AC15 V15.03.05.19_CN, and AC18 V15.03.05.19(6318)_CN devices. They allow remote code execution via shell metacharacters in the usbName field to the __fastcall function with a POST request.

An issue was discovered on Tenda AC7 V15.03.06.44_CN, AC9 V15.03.05.19(6318)_CN, AC10 V15.03.06.23_CN, AC15 V15.03.05.19_CN, 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.

Multiple Tenda devices are affected by authentication bypass, such as AC15V1.0 Firmware V15.03.05.20_multi?AC5V1.0 Firmware V15.03.06.48_multi and so on. an attacker can obtain sensitive information, and even combine it with authenticated command injection to implement RCE.

There is a command injection vulnerability at the /goform/setsambacfg interface of Tenda AC15 US_AC15V1.0BR_V15.03.05.20_multi_TDE01.bin device web, which can also cooperate with CVE-2021-44971 to cause unconditional arbitrary command execution
