CVE-2013-6077
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 · uneditedCitrix XenDesktop 7.0, when upgraded from XenDesktop 5.x, does not properly enforce policy rule permissions, which allows remote attackers to bypass intended restrictions.
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 confidenceCitrix XenDesktop 7.0 contains a privilege escalation vulnerability where policy rule permissions are not properly enforced after an upgrade from XenDesktop 5.x. This authorization bypass allows remote attackers to circumvent intended security restrictions and access resources or functionality they should not have.

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 checksWork through these to decide whether this CVE applies to you.
-
Identify XenDesktop versionCheck the installed XenDesktop version through the Desktop Studio console or by examining the installation, typically found in Add/Remove Programs or the Desktop Studio About sectionAffected if The version is exactly 7.0 (other versions are not affected by this specific CVE)
-
Determine upgrade historyReview installation documentation, check with IT administration records, or examine the Desktop Delivery Controller configuration to determine if the current XenDesktop 7.0 installation was upgraded from a XenDesktop 5.x versionAffected if The system was upgraded from XenDesktop 5.x to 7.0 - this vulnerability only affects upgraded environments, not fresh installations of 7.0
-
Inspect policy rules in Desktop StudioOpen Citrix Desktop Studio, navigate to Policies, and review all configured policy rules. Check for any policies that appear to have incorrect or overly permissive user/group assignments or that grant access beyond the intended scopeAffected if Policy rules grant excessive permissions to users or groups that should not have them, or show mismatched permission configurations
-
Verify policy permission enforcementIn Desktop Studio Policy settings, verify that each policy rule correctly enforces the intended security restrictions. Look for discrepancies between the configured permissions and the expected restrictions, particularly for user access controlsAffected if Policy permissions are not being enforced as configured, or unauthorized users can access restricted resources or functionality
A user is affected if they are running XenDesktop 7.0 that was upgraded from XenDesktop 5.x and policy rules show permission misconfigurations or unauthorized access is possible.

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.
From vendor dataOrganizations that upgraded from XenDesktop 5.x to 7.0 should audit and re-apply all policy rules to ensure proper permission enforcement, and apply any available vendor patches for this specific issue.
