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 · unedited
The server in Red Hat JBoss Operations Network (JON) before 3.3.6 allows remote attackers to execute arbitrary code via a crafted HTTP request, related to message deserialization.

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 confidence

The JBoss Operations Network server before version 3.3.6 is vulnerable to unsafe deserialization of incoming HTTP message data. An unauthenticated remote attacker can send a crafted HTTP request containing malicious serialized Java objects that, when processed by the server's deserialization routine, execute arbitrary code with the privileges of the affected service.

MitigationUpgrade JBoss Operations Network to version 3.3.6 or later. If immediate upgrading is not feasible, implement network segmentation to limit exposure and deploy WAF rules to block HTTP requests containing known Java deserialization attack patterns.

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 checks

Work through these to decide whether this CVE applies to you.

  1. Verify JBoss Operations Network is installed
    Locate the JBoss Operations Network installation by searching for the 'jboss-on' or 'jon' directories in common installation paths such as /opt, /usr/local, or the application's root directory. Check for the presence of the 'server' and 'bin' subdirectories typical of JBoss installations.
    Affected if The software is not present on the system, then this CVE does not apply.
  2. Identify the installed version
    Check the version file or startup scripts within the installation directory. Look for a version manifest, a 'version.txt' file, or examine the startup logs that typically display the server version on initialization.
    Affected if The version cannot be determined or the detected version is 3.3.5 or lower.
  3. Confirm the HTTP management interface is exposed
    Inspect the server configuration files (typically in the 'server' subdirectory) to determine if the HTTP-based management endpoint is enabled and bound to a network-accessible IP address. Check for 'http' connector definitions in the configuration.
    Affected if The HTTP interface is enabled and reachable over the network, making deserialization input possible.
  4. Check network accessibility of the HTTP service
    Use network scanning tools (such as netstat, nmap, or ss) to verify if the JBoss HTTP port (commonly port 8080 or 8443) is listening on an externally accessible IP address rather than localhost only.
    Affected if The HTTP service is bound to 0.0.0.0 or a public IP address, allowing remote attackers to send malicious requests.

A system is affected if JBoss Operations Network version 3.3.5 or earlier is installed with the HTTP interface enabled and network-accessible, allowing remote unauthenticated attackers to deliver malicious serialized Java objects.

dbcve · scoped
Upgrade available Upgrade to a release after 3.3.5
Interim mitigation

Upgrade JBoss Operations Network to version 3.3.6 or later. If immediate upgrading is not feasible, implement network segmentation to limit exposure and deploy WAF rules to block HTTP requests containing known Java deserialization attack patterns.

Recommended fix High confidence

JBoss Operations Network 3.3.6

  1. 1. Backup the current JBoss Operations Network installation and database before proceeding.
  2. 2. Download JBoss Operations Network 3.3.6 from the official Red Hat download channel (RHN or Red Hat customer portal).
  3. 3. Stop the JBoss Operations Network server services.
  4. 4. Follow the official upgrade documentation to install version 3.3.6, preserving configuration files where appropriate.
  5. 5. Start the JBoss Operations Network server services.
  6. 6. Verify the server is running correctly and all plugins/agents can connect.
  7. 7. Validate that the vulnerability is remediated by confirming the server responds normally to legitimate requests.
