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
In Talend Studio before 7.3.1-R2022-10 and 8.x before 8.0.1-R2022-09, microservices allow unauthenticated access to the Jolokia endpoint of the microservice. This allows for remote access to the JVM via the Jolokia JMX-HTTP bridge.

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

Talend Studio microservices expose the Jolokia endpoint without authentication, allowing remote attackers to access the JVM through the Jolokia JMX-HTTP bridge. This exposes MBean operations and JVM management functions that can lead to information disclosure or potential remote code execution.

MitigationUpdate Talend Studio to version 7.3.1-R2022-10 or later for 7.x, or 8.0.1-R2022-09 or later for 8.x. If immediate patching is not feasible, network-segment the affected microservices or disable the Jolokia endpoint.

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. Identify Talend Studio installation and version
    Locate the Talend Studio installation directory and check the version file (typically version.properties or similar in the installation root, or use 'Help > About' from the Studio UI). Compare the installed version against affected ranges: < 7.3.1-r2022-10 or >= 8.0.0 and < 8.0.1-r2022-09.
    Affected if The installed version falls within the affected ranges.
  2. Determine if Talend Studio microservices are running
    Check for running Java processes related to Talend, or look for running HTTP services on common ports (8080, 8081, 8082) used by Talend microservices. On Windows, use Task Manager or 'netstat -ano'; on Linux, use 'ps aux | grep talend' or 'netstat -tlnp'.
    Affected if Talend Studio or its microservices are running and accessible.
  3. Verify Jolokia endpoint exposure
    Attempt to access the Jolokia endpoint. Common paths include /jolokia, /actuator/jolokia, or /jolokia/read/java.lang:type=Runtime. Use curl or a browser: curl -s http://localhost:8080/jolokia (adjust port if different). A successful unauthenticated response indicates the endpoint is exposed.
    Affected if The Jolokia endpoint returns a valid JSON response without requiring authentication.
  4. Check network accessibility of the service
    Verify whether the Talend microservice port (commonly 8080 or as configured) is bound to 0.0.0.0 or an externally accessible IP rather than localhost only. Use 'netstat -ano | grep 8080' (or the observed port) and check the bind address. If bound to 0.0.0.0 or a non-loopback address, the service is network-accessible.
    Affected if The service is bound to an IP address other than 127.0.0.1 (localhost), making it remotely accessible.

You are affected if Talend Studio version is < 7.3.1-r2022-10 or >= 8.0.0 and < 8.0.1-r2022-09, AND the Jolokia endpoint is accessible without authentication on a network-accessible port.

Upgrade available Upgrade to 7.3.1-r2022-10 / 8.0.1-r2022-09 or later
Fixed in 7.3.1-r2022-108.0.1-r2022-09
Interim mitigation

Update Talend Studio to version 7.3.1-R2022-10 or later for 7.x, or 8.0.1-R2022-09 or later for 8.x. If immediate patching is not feasible, network-segment the affected microservices or disable the Jolokia endpoint.

Recommended fix High confidence

7.3.1-R2022-10 (for 7.x) or 8.0.1-R2022-09 (for 8.x)

  1. Identify the current Talend Studio version in use
  2. Download the fixed version from Talend's official download portal: 7.3.1-R2022-10 (for 7.x branch) or 8.0.1-R2022-09 (for 8.x branch)
  3. Backup all existing projects, configurations, and metadata
  4. Stop any running Talend Studio instance
  5. Install or apply the upgrade to the fixed version
  6. Start Talend Studio and verify the Jolokia endpoint is no longer exposed without authentication
  7. Confirm the vulnerability is remediated by attempting to access the Jolokia endpoint - it should now require authentication
