CVE-2026-15428: CWE-78 Improper neutralization of special elements used in an OS command ('OS command injection') in TP-Link Systems Inc. Archer VX1800v v1
CVE-2026-15428 is an OS command injection vulnerability in TP-Link Systems Inc. Archer VX1800v v1. It arises from insufficient input sanitization of the domain name parameter in the device's HTTP interface. An adjacent attacker with access to this interface can inject shell metacharacters, leading to arbitrary code execution with root privileges. Successful exploitation can result in complete device compromise.
AI Analysis
Technical Summary
This vulnerability (CVE-2026-15428) affects the Archer VX1800v v1 router from TP-Link Systems Inc. It involves improper neutralization of special elements used in OS commands (CWE-78). Specifically, the domain name parameter in the HTTP interface is not properly sanitized, allowing an adjacent attacker to inject shell metacharacters. This can lead to arbitrary code execution with root privileges, effectively allowing full control over the device. The CVSS 4.0 base score is 8.5, indicating high severity. No patch or official remediation is currently documented, and no known exploits in the wild have been reported.
Potential Impact
Exploitation of this vulnerability allows an attacker with adjacent network access to execute arbitrary commands on the device with root privileges. This can lead to full compromise of the affected router, including unauthorized control, data manipulation, or disruption of network services.
Mitigation Recommendations
Patch status is not yet confirmed — check the vendor advisory for current remediation guidance. Until an official fix is available, restrict access to the device's HTTP interface to trusted users only, and monitor for unusual activity. Avoid exposing the management interface to untrusted networks.
