CWE
- CWE-78 - Improper neutralization of special elements used in an OS command ('OS command injection')
Summary
An OS command injection vulnerability exists in the web management interface of Archer C20 v6 firmware when processing certain WAN-related configuration operations. An authenticated administrator may exploit insufficient input validation to execute arbitrary system commands, potentially resulting in full device compromise.
Successful exploitation may allow arbitrary command execution with elevated privileges, compromising the confidentiality, integrity, and availability of the affected device and network traffic passing through it.

CWE
- CWE-798 - Use of Hard-coded Credentials
Summary
A hardcoded credential
vulnerability exists in the firmware of multiple TP-Link routers (TL-WR845N v4, TL-WR850N v3, TL-WR902AC v4, Archer C20 v6 & Archer MR200 v5). Authentication-related credential material is
embedded within a password file in the firmware image and may be recovered
through firmware analysis.
Successful
exploitation could result in unauthorized access to privileged functions on
affected devices.

CWE
- CWE-78 - Improper neutralization of special elements used in an OS command ('OS command injection')
Summary
A command
injection vulnerability has been identified in the DHCP option processing logic
in multiple TP-Link router models, due to insufficient validation of externally
supplied DHCP option data. An adjacent attacker may exploit this
vulnerability by supplying crafted DHCP responses, potentially resulting in unauthorized
command execution during device initialization or provisioning workflows. This
typically occurs when the device is in a factory-default or unconfigured state.
Successful
exploitation may allow an adjacent, unauthenticated attacker to execute
arbitrary commands with elevated privileges, potentially leading to full
compromise of the affected device and unauthorized administrative control.
