CVE-2014-7839
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 · uneditedDocumentProvider in RESTEasy 2.3.7 and 3.0.9 does not configure the (1) external-general-entities or (2) external-parameter-entities features, which allows remote attackers to conduct XML external entity (XXE) attacks 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 · high confidenceRESTEasy's DocumentProvider fails to disable XML external entity processing by not configuring the external-general-entities and external-parameter-entities features in its XML parser. This allows attackers to inject malicious XML with external entity references to read sensitive files or perform server-side request forgery.

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 RESTEasy versionLocate the resteasy-core jar file in your application classpath or dependencies and check its version metadata (typically in MANIFEST.MF or pom.xml). Common paths include WEB-INF/lib/ or Maven/Gradle dependency declarations.Affected if The installed version is 2.3.7 or 3.0.9
-
Confirm DocumentProvider usageSearch your codebase for imports or references to org.jboss.resteasy.plugins.providers.DocumentProvider, or check if XML marshalling/unmarshalling is performed via RESTEasy's provider framework.Affected if DocumentProvider class is loaded or XML processing through RESTEasy providers is in use
-
Inspect XML parser configuration in DocumentProviderExamine the DocumentProvider source code or its XML parser factory configuration for the presence of XMLConstants.ACCESS_EXTERNAL_DTD and XMLConstants.ACCESS_EXTERNAL_SCHEMA properties, or look for explicit setting of external-general-entities and external-parameter-entities features to false.Affected if The parser configuration does not explicitly disable external-general-entities and external-parameter-entities features (these are not set to false)
You are affected if RESTEasy version 2.3.7 or 3.0.9 is deployed and the DocumentProvider XML parser is used without explicit XXE protection configured in the parser settings.

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 dataConfigure the DocumentProvider to disable external entity processing by enabling the XXE protection features (external-general-entities and external-parameter-entities set to false) in the XML parser configuration.
