CVE-2026-47367: UID Enterprise Agent Command Injection via Improper Input Validation

Executive Summary

A critical command injection vulnerability (CVE-2026-47367) has been identified in UID Enterprise Agent, an enterprise identity and access management (IAM) agent component. The vulnerability carries a CVSS score of 9.9 (Critical) and allows a malicious actor with network access and low privileges to exploit improper input validation to execute arbitrary commands on the host device.

CVSS Score: 9.9 (Critical) Published: 2026-06-12 Attack Path: Low-privilege network access → command injection → host code execution

Vulnerability Overview

Affected Products

UID Enterprise Agent is deployed in enterprise environments to handle authentication, authorization, and identity federation between systems. Its broad deployment footprint in IAM infrastructure makes this vulnerability particularly impactful.

Technical Details

What Is Command Injection?

Command injection occurs when user-controlled input is incorporated into an OS-level command without proper sanitization. The injected payload is interpreted by the shell or command processor as additional commands, resulting in arbitrary code execution with the privileges of the calling process.

Exploitation Mechanism

CVE-2026-47367 is rooted in Improper Input Validation in the UID Enterprise Agent. User-supplied input received over the network (with only low-level authentication required) is passed to a host-level command execution context without sufficient sanitization or parameterization.

1. Attacker with low-privilege network access sends crafted request to UID Enterprise Agent
2. Agent processes request and passes input to host command execution without sanitization
3. Attacker-controlled payload is executed as OS commands
4. Arbitrary code execution achieved on the host device
5. Attacker can escalate further, pivot within the network, or persist

Why CVSS 9.9?

The score reflects near-maximum severity:

• Network-accessible attack vector — exploitable from anywhere on the network
• Low privilege required — any authenticated user is a potential attacker
• No user interaction — fully automated exploitation is possible
• Host-level code execution — complete compromise of confidentiality, integrity, and availability

Impact Assessment

Recommendations

Immediate Actions

1. Apply vendor-provided patch as soon as it is released — monitor the vendor's security advisory channel
2. Restrict network access to the UID Enterprise Agent service to only authorized management hosts
3. Implement network segmentation around IAM infrastructure components
4. Monitor for anomalous command execution originating from the agent process

Network-Level Mitigations (Until Patch)

- Restrict UID Enterprise Agent ports to known management IP ranges via firewall ACLs
- Deploy host-based IDS rules to detect unusual process spawning from the agent process
- Enable verbose logging on the agent host for all network-initiated actions
- Consider isolating the agent host on a dedicated VLAN with strict egress filtering

Detection Indicators

Post-Remediation Checklist

1. Confirm vendor patch is applied and UID Enterprise Agent is updated
2. Audit all hosts running the agent for signs of prior compromise
3. Review IAM audit logs for unauthorized authentication decisions during the exposure window
4. Rotate credentials and tokens managed by the agent
5. Verify firewall rules restrict agent access to only necessary hosts
6. Conduct threat hunting across network segments accessible from the agent host
