CVE-2016-5062
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 web server in Aternity before 9.0.1 does not require authentication for getMBeansFromURL loading of Java MBeans, which allows remote attackers to execute arbitrary Java code by registering MBeans.
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 confidenceThe Aternity web server before version 9.0.1 lacks authentication enforcement on the getMBeansFromURL endpoint used for loading Java MBeans. This allows unauthenticated remote attackers to register malicious MBeans, enabling arbitrary Java code execution on the affected system.

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 Aternity installation and versionLocate the Aternity web server installation and determine the installed version number (typically found in product documentation, installed files, or administrative console)Affected if Installed version is 9.0 or earlier (versions 9.0 and below are affected)
-
Verify getMBeansFromURL endpoint accessibilityAttempt to access the getMBeansFromURL endpoint (typically at /api/getMBeansFromURL or similar path) without providing credentials to determine if authentication is requiredAffected if Endpoint responds without requiring authentication credentials
-
Check network exposure of Aternity serverDetermine if the Aternity web server is accessible from untrusted network segments or the public internetAffected if Server is directly exposed to untrusted networks without network-level access controls
Environment is affected if running Aternity version 9.0 or earlier AND the getMBeansFromURL endpoint accepts unauthenticated requests
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 · scopedUpgrade Aternity to version 9.0.1 or later, which enforces authentication on the getMBeansFromURL functionality. Until patched, restrict network access to the Aternity web server from untrusted sources.
9.0.1
- Upgrade Aternity to version 9.0.1 or later to remediate the unauthenticated MBean registration vulnerability
- Verify the upgrade was successful by confirming the version number in the Aternity administration console
- Test that the getMBeansFromURL endpoint now requires proper authentication before allowing MBean registration
