CVE-2014-3573
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 · uneditedThe oVirt Engine backend module, as used in Red Hat Enterprise Virtualization Manager before 3.4.2, uses an "insecure DocumentBuilderFactory," which allows remote attackers to read arbitrary files or possibly have other unspecified impact via a crafted XML/RSDL document, related to an XML External Entity (XXE) issue.
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 confidenceThis is an XML External Entity (XXE) injection vulnerability in oVirt Engine's backend module. The application uses an insecurely configured DocumentBuilderFactory that does not disable external entity processing, allowing remote attackers to submit crafted XML/RSDL documents that can reference external entities to read arbitrary files from the server or perform server-side request forgery-like attacks.

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.
-
Check the installed version of Red Hat Enterprise Virtualization ManagerRun 'rpm -q rhevm' or check the engine version via the administration portal or command line interfaceAffected if The installed version is 3.4.1 or earlier (the vulnerable version range is <= 3.4.1)
-
Locate the oVirt Engine backend XML parser configurationInspect the DocumentBuilderFactory configuration within the oVirt Engine backend module. This is typically found in configuration files or Java source code that handle XML/RSDL document parsingAffected if The DocumentBuilderFactory does not explicitly disable external entity processing (FEATURE_SECURE_PROCESSING, external-general-entities, or external-parameter-entities are not set to false)
-
Review XML parser settings for external entity resolutionCheck the XML parser configuration for settings related to DTD processing, external entity resolution, and XMLIncludes. Look for configurations that enable rather than disable external entity handlingAffected if External entity processing is enabled or not explicitly disabled in the parser configuration
-
Identify if XML or RSDL document processing is in useMonitor or inspect network traffic and application logs for incoming XML or RSDL document submissions to the oVirt Engine backendAffected if The application processes XML or RSDL documents from untrusted sources without sanitizing for XXE payloads
A system is affected if it runs Red Hat Enterprise Virtualization Manager version 3.4.1 or earlier AND processes XML/RSDL documents through the backend module with an insecurely configured DocumentBuilderFactory.

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 dataUpgrade to Red Hat Enterprise Virtualization Manager 3.4.2 or later, which includes a secure DocumentBuilderFactory configuration. If immediate upgrading is not feasible, modify XML parser configuration to disable external entities, DTD processing, and external entity resolution.
