DescriptionCVE.org

A malicious actor with access to the network and low privileges could exploit an Improper Input Validation vulnerability found in UID Enterprise Agent to execute a Command Injection on the host device.

AnalysisAI

Command injection in Ubiquiti UID Enterprise Agent allows a low-privileged attacker with network access to execute arbitrary commands on the host device by abusing improper input validation. The CVSS 9.9 score reflects a scope change with high confidentiality, integrity, and availability impact, and no public exploit identified at time of analysis. Defenders should treat this as a high-priority patch item given the low attack complexity and minimal privilege requirement.

Technical ContextAI

UID Enterprise Agent is Ubiquiti's identity/access-management endpoint agent used in enterprise deployments to bridge identity providers and network access enforcement on Ubiquiti infrastructure. The root cause class is CWE-20 (Improper Input Validation): user-supplied input is passed to a downstream command-execution context without sufficient sanitization, allowing operating-system command injection on the host running the agent. Because the agent typically runs with elevated privileges to manage host or network state, injected commands inherit that execution context, which aligns with the CVSS scope-change (S:C) designation.

RemediationAI

Patch available per vendor advisory - consult Ubiquiti Security Advisory Bulletin 065 at https://community.ui.com/releases/Security-Advisory-Bulletin-065-065/aa46a22b-fc43-4eae-9382-6fc8feda967a for the fixed UID Enterprise Agent build and upgrade all deployed agents to that version. Until patching is complete, restrict network reachability to the UID Enterprise Agent management/API interface to trusted administrative subnets via host or network ACLs, and tighten the population of accounts holding the low-privilege role required for exploitation (audit and revoke unnecessary access), accepting that ACL changes may disrupt legitimate identity-bridging traffic if the agent is broadly consumed by other UniFi components. Monitor host process trees on systems running the agent for unexpected child processes (shell, scripting interpreters) spawned by the agent service as a detection compensating control.
