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.

CVE-2026-11834 (GCVE-0-2026-11834)
Vulnerability from cvelistv5
Published
2026-06-22 17:53
Modified
2026-06-26 21:14
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.
