CVE-2019-10883: Citrix SD-WAN Center and NetScaler SD-WAN Center command injection

Citrix · Citrix Sd Wan Center

Citrix SD-WAN Center 10.2.x before 10.2.1 and NetScaler SD-WAN Center 10.0.x before 10.0.7 are affected by OS command injection (CWE-78). The flaw allows an unauthenticated remote attacker to execute arbitrary commands on the appliance, which is a critical management component of an SD-WAN deployment.

Automated analysis

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

critical priorityCVSS 9.8 with network-reachable, unauthenticated command injection and public exploit material makes this a critical patching priority.

What it is

Citrix SD-WAN Center 10.2.x before 10.2.1 and NetScaler SD-WAN Center 10.0.x before 10.0.7 are affected by OS command injection (CWE-78). The flaw allows an unauthenticated remote attacker to execute arbitrary commands on the appliance, which is a critical management component of an SD-WAN deployment.

Impact

An attacker can run arbitrary operating system commands on the SD-WAN Center host, leading to full compromise of the management appliance and potential lateral movement into the managed SD-WAN fabric.

Attack surface

The CVSS vector is network-reachable with no privileges and no user interaction (AV:N/AC:L/PR:N/UI:N), so the vulnerable endpoint is directly reachable over the network without authentication. No specific interface or parameter is described in the record.

Exploitation

Not listed in CISA KEV and no ransomware association is documented, but EPSS is 0.65488 (99.2nd percentile) and a Tenable reference is tagged Exploit, indicating public exploit material exists.

What to do

  • Upgrade Citrix SD-WAN Center to 10.2.1 or later and NetScaler SD-WAN Center to 10.0.7 or later per vendor advisory CTX247737.
  • Restrict network access to the SD-WAN Center management interface to trusted administrative networks only.
  • Place the management interface behind a firewall or VPN and avoid exposing it to the internet.
  • Monitor vendor advisories for updated guidance and confirm no unsupported versions remain in the environment.

Detection

  • Review SD-WAN Center and host logs for unexpected child processes or shell commands spawned by the management service.
  • Alert on anomalous outbound connections or process execution from the SD-WAN Center appliance.
  • Audit network exposure of SD-WAN Center management interfaces and flag any internet-facing instances.

This assessment is produced automatically and is not human-reviewed. Verify against the vendor advisory before acting on it.
