CVE-2006-5792: XLink Omni-NFS Enterprise unspecified remote code execution

Automated analysis

Generated by VULONE's analysis model from the NVD record, CISA KEV and EPSS data on 19 September 2026. Confidence: low.

high priorityNetwork-reachable, unauthenticated code execution with a public exploit reference and very high EPSS, though technical details and patch status are unconfirmed.

What it is

XLink Omni-NFS Enterprise contains an unspecified vulnerability that allows remote attackers to execute arbitrary code. The disclosure provides no technical detail about the flaw itself, only a reference to a remote exploit module (vd_xlink2.pm), so the exact vulnerable component and mechanism are unknown. It matters because a network-reachable code execution flaw in an NFS server product can give an unauthenticated attacker full control of the host.

Impact

An attacker can execute arbitrary code on the affected system, likely with the privileges of the Omni-NFS service. That yields host compromise and potential access to any data or network shares the server exposes.

Attack surface

The CVSS vector AV:N/AC:L/Au:N indicates the flaw is reachable over the network with no authentication and no user interaction. The description does not identify which service, port or protocol path is involved, so the precise entry point cannot be confirmed from this record.

Exploitation

No CISA KEV listing and no ransomware association are recorded, but the references include an exploit-tagged link to a public exploit module, and EPSS is high at roughly 0.60 (99th percentile), indicating elevated likelihood of exploitation activity.

What to do

• Apply the vendor patch or fixed Omni-NFS Enterprise release if one is available; the record does not name affected or fixed versions, so confirm with XLink support.
• If no patch exists, restrict network access to the Omni-NFS service to trusted hosts only and block it at the perimeter.
• Run the service with least privilege and isolate the host on a segmented network away from sensitive data.
• Monitor vendor and CVE channels for updated technical details, since the original disclosure had no actionable information.

Detection

• Monitor for unexpected child processes or command shells spawned by the Omni-NFS service process.
• Alert on inbound connections to Omni-NFS ports from untrusted or unusual source addresses.
• Review host and NFS logs for anomalous file operations, new files, or service restarts around suspicious connections.
• Hunt for known exploit artifacts or module names such as vd_xlink2.pm in tooling or process telemetry.
