| Exploitation Conditions | Attacker must have network reachability to the UID Enterprise Agent service and a valid low-privilege account on the agent (PR:L per CVSS), but does not need administrative rights or any user interaction (UI:N). No special non-default configuration is called out in the description - any deployment of UID Enterprise Agent exposing its service to holders of low-privilege credentials is exploitable. Exploitation is limited by the requirement that the attacker first obtain such a low-privileged credential and by any network segmentation restricting who can reach the agent. |
| Impact | All signals point to high real-world risk: CVSS 3.1 vector AV:N/AC:L/PR:L/UI:N/S:C/C:H/I:H/A:H scores 9.9, indicating network-reachable, low-complexity exploitation requiring only low privileges and no user interaction, with cross-scope full-impact consequences. There is no public exploit identified at time of analysis and the CVE is not listed in CISA KEV, so EPSS-style mass-exploitation pressure is not yet evidenced. The PR:L requirement is the main mitigating factor - any low-privileged account or low-trust network role that can reach the agent is sufficient, which in enterprise identity-agent deployments is a low bar. EPSS score was not provided in the input, so probabilistic exploitation likelihood cannot be quantified. |
| Exploit ScenarioDerived | An attacker who has obtained a low-privileged account on the UID Enterprise Agent - for example via a phished helpdesk credential or a reused tenant identity - connects to the agent over the network and submits a crafted request containing shell metacharacters in a field that the agent passes unsanitized into an OS command. The agent executes the injected command on the host with its own privileges, enabling the attacker to read configuration, pivot into the Ubiquiti management plane, or stage further tools. No public exploit identified at time of analysis, but the low complexity makes weaponization straightforward once the vulnerable parameter is known. |

Alert meAnalysisAIv1 – Jun 12, 2026
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.
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.

Technical ContextAI · show details
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.

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.
Executive ViewAI
Ubiquiti UID Enterprise Agent contains a critical vulnerability (CVE-2026-47367, CVSS 9.9) enabling remote command execution on networked devices; no patch is currently available. Organizations operating this product face immediate risk of complete system compromise across their Ubiquiti infrastructure, requiring urgent defensive measures.
No vendor-released patch identified at time of analysis. Interim mitigations: (1) Restrict network access to Ubiquiti UID Enterprise Agent through firewall rules and network segmentation; (2) Disable the Agent on non-critical systems where operationally feasible; (3) Deploy network-based intrusion detection signatures to detect command injection patterns; (4) Monitor affected systems for suspicious process execution and unexpected network connections; (5) Implement strict access controls limiting exposure to trusted internal networks only.
