Official description Straight from the sourceThe vendor's or NVD's own wording, published unedited. Authoritative, but often terse — it says what broke, rarely what to do.

NVD · unedited
Improper input validation in Citrix XenMobile Server 10.12 before RP3, Citrix XenMobile Server 10.11 before RP6, Citrix XenMobile Server 10.10 RP6 and Citrix XenMobile Server before 10.9 RP5 allows SQL Injection.

Technical summary Written by usOur analysis, written from the advisory, the CVSS vector and the affected-version data. It adds context the advisory leaves out, and never invents facts that are not in the source.

dbcve analysis · high confidence

SQL injection vulnerability in Citrix XenMobile Server due to improper input validation. Attackers can inject malicious SQL queries through unsanitized input fields to access, modify, or delete database contents.

MitigationApply the vendor-supplied rollup patches: RP3 for version 10.12, RP6 for version 10.11, and RP5 for version 10.9. Prioritize patching given the critical CVSS score and potential for complete system compromise.

Am I affected? How to checkSteps we derive from the advisory and the affected-version data, so you can decide whether this CVE reaches your setup. They are a guide, not a scan — your own configuration is the authority.

dbcve checks

Work through these to decide whether this CVE applies to you.

  1. Determine XenMobile Server version
    Log into the XenMobile Server console and navigate to Settings > About, or run 'sudo /opt/ZDM/bin/zdm -version' from the server command line
    Affected if The displayed version is 10.8.0 or lower, or exactly 10.9.0, 10.10.0, 10.11.0, or 10.12.0
  2. Confirm the server is operational
    Verify the XenMobile services are running by checking service status or attempting to access the web-based management console at port 443
    Affected if The server is running and accessible, making the SQL injection interface exposed
  3. Identify exposed input interfaces
    Check which management or user-facing web interfaces are enabled on the server, typically found in the XenMobile console under Configure > Devices or Configure > Apps settings pages
    Affected if Any web-based input fields for device enrollment, app configuration, or user management are accessible without additional authentication hardening
  4. Review patch application status
    Query the system for installed rollup patches: check /opt/ZDM/var/patches/ or run 'rpm -qa | grep -i zdm' to list applied patch packages
    Affected if No vendor rollup patches (RP3 for 10.12, RP6 for 10.11, RP5 for 10.9) are installed on the affected version

The environment is affected if XenMobile Server version 10.8.0 or lower, or exactly 10.9.0/10.10.0/10.11.0/10.12.0 is installed and running with web interfaces accessible, and no corresponding vendor rollup patches have been applied.

Remediation Closing itWhat it takes to close this. Where a vendor fix exists we point at it; where none exists we say so plainly, and can build one. Effort estimates are scoped from the advisory, not from your codebase.

dbcve · scoped
Upgrade available Upgrade to a release after 10.8.0
Interim mitigation

Apply the vendor-supplied rollup patches: RP3 for version 10.12, RP6 for version 10.11, and RP5 for version 10.9. Prioritize patching given the critical CVSS score and potential for complete system compromise.

Recommended fix High confidence

XenMobile Server 10.12 RP3, 10.11 RP6, 10.10 RP6, or 10.9 RP5 (depending on your baseline release line)

  1. 1. Identify the current installed version of Citrix XenMobile Server by accessing the admin console or checking system information.
  2. 2. Based on your current version, upgrade to one of the following fixed releases: XenMobile Server 10.12 RP3 or later, XenMobile Server 10.11 RP6 or later, XenMobile Server 10.10 RP6 or later, or XenMobile Server 10.9 RP5 or later.
  3. 3. Obtain the appropriate upgrade package from support.citrix.com or the Citrix download portal.
  4. 4. Follow Citrix's standard upgrade procedure for XenMobile Server, which typically includes: backing up the current configuration, placing the server in maintenance mode, applying the upgrade, and validating the installation.
  5. 5. After upgrade, verify the SQL Injection vulnerability is remediated by confirming the version matches the fixed release criteria.
Caveat Review Citrix upgrade documentation for your specific version path as upgrades between major release lines may require intermediate steps
