Technical details

The UniFi Access Application is vulnerable to command injection due to improper input validation (CWE-20). An attacker authenticated with low privileges can send specially crafted network requests to the application to execute arbitrary system commands on the underlying host. The vulnerability is rated critical (CVSS 9.9) because it allows for a scope change, meaning the attacker can move from the application layer to the host operating system with full confidentiality, integrity, and availability impact. The issue is resolved in UniFi Access Application version 4.2.29 and later.
