| Exploitation Conditions | Exploitation requires the attacker to already possess high privileges (CVSS PR:H) and network access (AV:N) to the UID Enterprise Agent; it is therefore not remotely exploitable by an unauthenticated actor against a default install. No user interaction is needed (UI:N) and attack complexity is low (AC:L), so once the privilege and network-reach prerequisites are met, triggering the command injection is straightforward. Limiting factors that reduce real-world risk: the mandatory high-privilege authentication, the need for network reachability to the agent, and the specific requirement to reach the improperly-validated input path within the agent. |
| Impact | The signals are partially conflicting: the CVSS base score of 9.1 is high, but the network attack vector (AV:N) is gated by a high-privilege requirement (PR:H), meaning an attacker must already hold elevated access before exploiting the flaw - this substantially narrows the realistic threat population to insiders, compromised admin credentials, or post-exploitation lateral movement rather than opportunistic internet-wide attacks. There is no EPSS score, no POC, and no KEV listing in the provided data, so there is no evidence of active or automatable exploitation; the high score is impact-driven, not exploitability-driven. Given the low barrier once privileges are held (AC:L, UI:N) and full host takeover potential, any operator running UID Enterprise Agent should still prioritize patching promptly, but this reads as an elevated-priority insider/post-compromise risk rather than a mass-exploitation emergency. |
| Exploit ScenarioDerived | An attacker who has already obtained high-privilege access to the UID Enterprise Agent - for example via stolen admin credentials or from an adjacent compromised system - sends crafted input over the network to the agent, which fails to validate it and passes it to a host command. The injected command executes on the host device with the agent's privileges, giving the attacker full control and a pivot point into the environment. No public exploit code is known at time of analysis. |

Alert meAnalysisAIv1 – Aug 26, 2026
Command injection in Ubiquiti's UID Enterprise Agent lets a high-privileged, network-adjacent actor run arbitrary OS commands on the host device by supplying improperly validated input. The flaw carries a CVSS 9.1 rating driven by a scope change and full compromise of confidentiality, integrity, and availability, though exploitation requires existing high privileges (PR:H). No public exploit has been identified at time of analysis, and it is not listed in CISA KEV.
RemediationAI
Patch available per vendor advisory - upgrade UID Enterprise Agent to the fixed release identified in Ubiquiti Security Advisory Bulletin 067 (https://community.ui.com/releases/Security-Advisory-Bulletin-067/fc4a3488-7c43-4628-8bab-f715e96dbfc9); the exact fixed version was not provided in the input and should be confirmed from that advisory. Until patched, reduce exposure by restricting network reachability of the agent's management/control interface to trusted administrative hosts only, tightening who holds the high-privilege accounts required to reach the vulnerable input path, and monitoring the agent host for anomalous child-process or command execution. Note the trade-off: restricting the agent's network interface may disrupt legitimate central management functions, so validate against your deployment before enforcing.

Technical ContextAI · show details
UID Enterprise Agent is Ubiquiti's identity/endpoint agent component (cpe:2.3:a:ubiquiti_inc:uid_enterprise_agent). The root cause is CWE-20 (Improper Input Validation): the agent accepts input over the network and passes it into a host command context without adequate sanitization, enabling OS command injection. Because commands execute in the agent's process/host context and the CVSS scope is marked Changed (S:C), the impact reaches beyond the vulnerable component into the underlying host device, which is why all three impact metrics are High.

Lifecycle Timeline
2DescriptionCVE.org
A malicious actor with access to the network and high 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 command injection vulnerability (CVSS 9.1) that enables high-privileged network-adjacent actors to execute arbitrary OS commands and fully compromise affected systems. This poses an immediate risk to organizations managing network infrastructure through UID Enterprise, particularly if administrative credentials are exposed or internal threat actors have privileged access. With no vendor patch currently available, remediation requires urgent network containment and access controls.
No vendor-released patch identified at time of analysis. Interim mitigations: enforce network segmentation isolating UID Enterprise Agent to administrative-only subnets; require multi-factor authentication for all administrative access; implement command execution monitoring and alerting; consider temporary operational mode restrictions if feasible for your environment; establish daily security logs review for the affected systems.
