CVE-2019-20635
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 · uneditedcodeBeamer before 9.5.0-RC3 does not properly restrict the ability to execute custom Java code and access the Java class loader via computed fields.
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 confidencecodeBeamer before 9.5.0-RC3 fails to properly restrict its computed fields feature, allowing authenticated users to execute arbitrary custom Java code and access the Java class loader. This enables server-side code execution and potential privilege escalation.

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 installed codeBeamer versionLocate the codeBeamer version information in the application administration interface or check the version file in the installation directoryAffected if The installed version is 9.4.0 or earlier, or exactly 9.5.0 (not 9.5.0-RC3 or later)
-
Verify computed fields feature statusAccess the administration or configuration panel and locate the computed fields feature settings to determine if it is enabledAffected if The computed fields feature is enabled and accessible to users
-
Review computed field permissionsExamine the permission configuration for computed fields to determine which user roles can create or modify computed field definitionsAffected if Non-administrator users or untrusted accounts have permission to create or edit computed fields
-
Inspect existing computed field definitionsReview the list of configured computed fields in the application for any that invoke Java class loader methods, reflection, or execute custom Java codeAffected if Any computed field definitions contain suspicious code patterns such as class loader access, arbitrary Java execution, or potentially malicious scripts
You are affected if your codeBeamer version is 9.4.0 or earlier, or exactly 9.5.0, and the computed fields feature is enabled with permissions granted to non-administrator users.
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.
From vendor dataUpgrade to codeBeamer 9.5.0-RC3 or later. Until upgraded, restrict computed field permissions to only trusted administrators and monitor for suspicious usage patterns.
