High CVSS 8.5
CVE-2026-15428
NVD analysis in progress
An OS command injection vulnerability exists in Archer VX800v v1 due to insufficient input sanitization of the domain name parameter. An adjacent attacker who can access the relevant HTTP interface can modify the parameter to inject shell metacharacters, resulting in arbitrary code execution with root privileges. Successful exploitation may allow remote code execution and complete compromise of the device.
What this means
- Exposure
- Exploitable from the adjacent network, with a privileged account and with no action from the victim.
- Impact
- An attacker can read sensitive data, modify or destroy data and take the service offline.
- Weakness
- Unfiltered input reaches the system shell, letting the attacker run their own commands on the server.
- Likelihood
- Its EPSS score stays low: nothing points to imminent exploitation, which is no reason to leave it unpatched.
What to doFold into the next patch cycle.
