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
There are Unauthenticated File Upload Vulnerabilities in Citrix XenMobile Server 10.8 before RP2 and 10.7 before RP3.

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

Unauthenticated file upload vulnerabilities in Citrix XenMobile Server 10.8 before RP2 and 10.7 before RP3 allow remote attackers to upload arbitrary files without authentication. This critical severity flaw (CVSS 9.8) likely enables remote code execution by uploading malicious files such as web shells to the server's web root.

MitigationUpgrade Citrix XenMobile Server to version 10.8 RP2 or 10.7 RP3 or later to patch the unauthenticated file upload vulnerability. If immediate patching is not possible, restrict network access to the XenMobile management interfaces via firewall or VPN.

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. Confirm Citrix XenMobile Server is installed
    Locate the XenMobile Server installation by checking for the service process or consulting your software inventory. On the server, look for the Citrix XenMobile service running on typical management ports (8443 for Console, 443/4443 for MDM/WEB).
    Affected if XenMobile Server is found running in the environment
  2. Identify the installed XenMobile version
    Access the XenMobile Console or check the server's installation directory for version information. The version is typically displayed on the login page or in the 'About' section of the administrative interface.
    Affected if The displayed version is 10.7.x or 10.8.x
  3. Verify the exact RP (Rollup Patch) level
    In the XenMobile Console, navigate to the Support or Settings > System > About page to view the full version string including the RP number. Alternatively, check the installed hotfixes or patches listed in the system information.
    Affected if Version shows 10.8 without RP2 or later, or 10.7 without RP3 or later, or the RP level cannot be determined (indicating a pre-patch state)
  4. Confirm the server is exposed to network
    Verify that the XenMobile management interfaces (ports 443, 4443, 8443) are accessible from untrusted networks. Check firewall rules and determine if the server is directly internet-facing.
    Affected if The management interface is exposed to the internet or untrusted networks without VPN or ACL restrictions

The environment is affected if Citrix XenMobile Server version 10.8 before RP2 or 10.7 before RP3 is installed and the management interface is network-accessible.

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.

Mitigation available No clean upgrade yet — mitigate in the meantime
Mitigation

Upgrade Citrix XenMobile Server to version 10.8 RP2 or 10.7 RP3 or later to patch the unauthenticated file upload vulnerability. If immediate patching is not possible, restrict network access to the XenMobile management interfaces via firewall or VPN.

Recommended fix High confidence

XenMobile Server 10.8 RP2 or later, or XenMobile Server 10.7 RP3 or later

  1. Identify the current XenMobile Server version by checking the server management console or system information
  2. If running XenMobile Server 10.8, verify the patch level - upgrade to RP2 or later if currently before RP2
  3. If running XenMobile Server 10.7, verify the patch level - upgrade to RP3 or later if currently before RP3
  4. Consult Citrix support.citrix.com for the official upgrade procedure and download the appropriate patch
  5. Apply the upgrade in accordance with Citrix documentation, ensuring proper backup of configuration and data before proceeding
  6. After upgrade, verify the system is functioning correctly and the vulnerability is remediated
Caveat Standard upgrade precautions apply - backup configuration before applying patches; test in non-production environment first if possible
