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
XML external entity (XXE) vulnerability in Citrix XenMobile Server 9.x and 10.x before 10.5 RP3 allows attackers to obtain sensitive information via unspecified vectors.

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 · moderate confidence

This is an XML External Entity (XXE) injection vulnerability in Citrix XenMobile Server versions 9.x and 10.x before 10.5 RP3. The vulnerability allows attackers to inject malicious XML payloads that can be parsed by the application, potentially allowing unauthorized access to local files, internal resources, or sensitive information through crafted entity references.

MitigationUpgrade Citrix XenMobile Server to version 10.5 RP3 or later. Additionally, ensure the XML parser is configured to disable external entity processing as a defense-in-depth measure.

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. Identify if Citrix XenMobile Server is deployed
    Locate the XenMobile Server installation directory or check running services for the XenMobile process
    Affected if The server is installed and running but the version cannot be determined or is below 10.5 RP3
  2. Determine the installed XenMobile Server version
    Access the XenMobile admin console and navigate to the version information page, or use the system command to retrieve the installed build number
    Affected if The version is 9.0, 10.0, 10.1, 10.3, 10.3.5, 10.3.6, 10.4, or 10.5 (any version before 10.5 RP3)
  3. Verify the XML parser configuration
    Inspect the XML parser configuration files or settings that handle XML input processing within the XenMobile Server
    Affected if External entity processing is enabled in the XML parser configuration
  4. Review XML processing endpoints
    Identify and examine the XML-handling endpoints or services within XenMobile that accept XML input
    Affected if The application processes XML without disabling external entity resolution

A user is affected if XenMobile Server version 9.0 through 10.5 is installed and the XML parser has external entity processing enabled, allowing crafted XXE payloads to be processed.
