info:
  name: Citrix SD-WAN Center - Remote Command Injection
  author: gy741
  severity: critical
  description: |
    Citrix SD-WAN Center is susceptible to remote command injection via the trace_route function in DiagnosticsController, which does not sufficiently validate or sanitize HTTP request parameter values used to construct a shell command. An attacker can trigger this vulnerability by routing traffic through the Collector controller and supplying a crafted value for ipAddress, thereby potentially being able to obtain sensitive information, modify data, and/or execute unauthorized operations.
  impact: |
    Successful exploitation of this vulnerability can lead to unauthorized access, data exfiltration, and potential compromise of the entire SD-WAN infrastructure.
  remediation: |
    Apply the necessary patches or updates provided by Citrix to mitigate the vulnerability.
