Title
Authenticated Command Injection on TP-Link TL-WR802N, TL-WR841N and TL-WR840N
Summary
A command injection vulnerability was identified in TP-Link TL-WR802N v4, TL-WR841N v14, and TL-WR840N v6 due to improper neutralization of special elements used in an OS command. In the router configuration import function allows an authenticated attacker to upload a crafted configuration file that results in execution of OS commands with root privileges during port-trigger processing.
Successful exploitation allows an authenticated attacker to execute system commands with root privileges, leading to full device compromise.

Title
TP-Link TL-WR841N ated_tp Command Injection Remote Code Execution Vulnerability
Summary
TP-Link TL-WR841N ated_tp Command Injection Remote Code Execution Vulnerability. This vulnerability allows network-adjacent attackers to execute arbitrary code on affected installations of TP-Link TL-WR841N routers. Authentication is not required to exploit this vulnerability.
The specific flaw exists within the ated_tp service. The issue results from the lack of proper validation of a user-supplied string before using it to execute a system call. An attacker can leverage this vulnerability to execute code in the context of root. Was ZDI-CAN-21825.

Title
Authenticated Command Injection on TP-Link TL-WR802N, TL-WR841N and TL-WR840N
Summary
A command injection vulnerability was identified in TP-Link TL-WR802N v4, TL-WR841N v14, and TL-WR840N v6 due to improper neutralization of special elements used in an OS command. In the router configuration import function allows an authenticated attacker to upload a crafted configuration file that results in execution of OS commands with root privileges during port-trigger processing.
Successful exploitation allows an authenticated attacker to execute system commands with root privileges, leading to full device compromise.

Title
TP-Link TL-WR841N ated_tp Command Injection Remote Code Execution Vulnerability
Summary
TP-Link TL-WR841N ated_tp Command Injection Remote Code Execution Vulnerability. This vulnerability allows network-adjacent attackers to execute arbitrary code on affected installations of TP-Link TL-WR841N routers. Authentication is not required to exploit this vulnerability.
The specific flaw exists within the ated_tp service. The issue results from the lack of proper validation of a user-supplied string before using it to execute a system call. An attacker can leverage this vulnerability to execute code in the context of root. Was ZDI-CAN-21825.
