CVE-2022-2838
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 · uneditedIn Eclipse Sphinx™ before version 0.13.1, Apache Xerces XML Parser was used without disabling processing of referenced external entities allowing the injection of arbitrary definitions which is able to access local files and expose their contents via HTTP requests.
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 Eclipse Sphinx before version 0.13.1. The Apache Xerces XML Parser is configured to process referenced external entities, allowing attackers to inject malicious XML that can read local files and trigger HTTP requests to internal systems.

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.
-
Determine Eclipse Sphinx versionRun 'pip show sphinx' or check the package version in your dependency file (requirements.txt, Pipfile.lock, or pyproject.toml)Affected if Version is 0.7.0 or higher but lower than 0.13.1
-
Identify XML file processingSearch your Sphinx project for XML files (look for .xml extensions) and review any custom directives or extensions that parse XML contentAffected if Your Sphinx project processes or includes XML files that could be supplied by external contributors
-
Check Xerces parser configurationReview any Java or Python code that initializes the Apache Xerces XML parser and examine the parser feature settings for external entity and DTD processingAffected if The Xerces parser is configured with default settings that enable external entity processing (features for 'external-general-entities', 'external-parameter-entities', or 'dtd' are not explicitly disabled)
-
Audit custom extensionsExamine any third-party or custom Sphinx extensions in your 'ext' directory for XML parsing operations using xerces or lxmlAffected if Custom extensions contain XML parsing logic that processes untrusted XML input without disabling external entities
Your environment is affected if you run Eclipse Sphinx version 0.7.0 through 0.13.0 and process untrusted XML files with the default Xerces parser configuration that allows external entity processing.
Generated from the published advisory. Verify against your own configuration.
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.
dbcve · scoped0.13.1
Disable external entity processing and DTD processing in the Apache Xerces XML Parser configuration. Update to version 0.13.1 or later if available.
0.13.1
- 1. Back up your current Sphinx project and configuration files.
- 2. Identify your build system (Maven, Gradle, or direct JAR replacement).
- 3. Update the Eclipse Sphinx dependency version to 0.13.1 in your project's dependency management (pom.xml, build.gradle, or equivalent).
- 4. If using Maven, run 'mvn clean compile' or 'mvn clean package' to download and verify the new dependency.
- 5. If using direct JAR files, replace the old org.eclipse.sphinx.* JARs with version 0.13.1 JARs from the Eclipse Maven repository or Eclipse Sphinx downloads.
- 6. Rebuild your project and test that Sphinx functionality works correctly with the new version.
- 7. Verify that XML parsing no longer processes external entities by testing with a sample XXE payload if you have security testing in place.
