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 Apache Storm Logviewer daemon exposes HTTP-accessible endpoints to read/search log files on hosts running Storm. In Apache Storm versions 0.9.1-incubating to 1.2.2, it is possible to read files off the host's file system that were not intended to be accessible via these endpoints.

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 Apache Storm Logviewer daemon contains a path traversal vulnerability in its HTTP-accessible endpoints that allows unauthorized reading of arbitrary files from the host filesystem beyond the intended log directory scope, enabling attackers to access sensitive system files.

MitigationUpgrade Apache Storm to version 1.2.3 or later where the vulnerability is patched, or disable the logviewer daemon if not required in production environments.

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 Apache Storm installation and version
    Locate the Storm installation directory and check the version file or run 'storm version' command if Storm is in PATH. Common locations include /opt/apache-storm, /usr/local/storm, or a user-installed directory. Compare the version against the affected range: 0.9.1 through 1.2.2.
    Affected if The installed version falls within 0.9.1 to 1.2.2 inclusive
  2. Verify if the logviewer daemon is enabled or running
    Check for the logviewer process or service. This may appear as 'logviewer' in process listings (ps aux), or as a configured component in Storm's conf/ directory. Inspect the logviewer configuration file if one exists in the Storm distribution.
    Affected if The logviewer daemon is running or is configured to run
  3. Confirm HTTP accessibility of logviewer
    Determine if the logviewer HTTP endpoint is accessible. This typically listens on port 8000 or 8080. Check firewall rules, bind addresses in configuration, and whether the logviewer process is bound to an interface accessible to potential attackers.
    Affected if The logviewer HTTP port is reachable from untrusted networks or allows unauthenticated access

A user is affected if running Apache Storm version 0.9.1-1.2.2 with the logviewer daemon enabled and its HTTP interface accessible, as this combination allows path traversal exploitation.
