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
** UNSUPPORTED WHEN ASSIGNED ** Improper Neutralization of Special Elements used in a Command ('Command Injection') vulnerability in Apache Software Foundation Apache UIMA DUCC. When using the "Distributed UIMA Cluster Computing" (DUCC) module of Apache UIMA, an authenticated user that has the permissions to modify core entities can cause command execution as the system user that runs the web process. As the "Distributed UIMA Cluster Computing" module for UIMA is retired, we do not plan to release a fix for this issue. NOTE: This vulnerability only affects products that are no longer supported by the maintainer.

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

Apache UIMA DUCC (Distributed UIMA Cluster Computing) contains a command injection vulnerability where an authenticated user with permissions to modify core entities can execute arbitrary commands as the user running the web process. The vulnerability stems from improper neutralization of special elements in commands.

MitigationSince the DUCC module is retired with no planned fix, organizations should verify if the component is in use and either remove it or implement compensating controls such as strict role-based access constraints, network isolation, and enhanced monitoring of authenticated sessions.

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. Check if Apache UIMA DUCC is installed
    Search for UIMA DUCC installation directories or files: look for 'ducc' directories, check common locations like /opt/ducc, /usr/local/ducc, or search for 'uima-ducc' in installed packages using 'dpkg -l | grep uima' or 'rpm -qa | grep uima'
    Affected if Apache UIMA DUCC is found installed on the system
  2. Check if DUCC web service is running
    Identify processes listening on common DUCC web ports (typically port 8080 or configured ports): run 'netstat -tlnp | grep -E "(8080|port)"' or 'ps aux | grep -i ducc' to find running DUCC Java processes
    Affected if DUCC web service process is running and accessible on a network port
  3. Check for configured DUCC users with permissions
    Examine DUCC user configuration files in the DUCC installation directory, typically in 'security' or 'configuration' subdirectories: look for user definition files that indicate which users have 'core entity modify' or administrative permissions
    Affected if Any DUCC user account exists with permissions to modify core entities (not read-only roles)
  4. Check web service configuration for authentication
    Review DUCC web configuration files for authentication settings: check if the web interface has authentication enabled or if it allows anonymous access
    Affected if Web interface authentication is disabled or permits unauthenticated access to entity modification features

User is affected if Apache UIMA DUCC is installed, the web service is running, and there exist authenticated users with permissions to modify core entities, since the vulnerability allows command injection through those modification capabilities.

Mitigation available No clean upgrade yet — mitigate in the meantime
Mitigation

Since the DUCC module is retired with no planned fix, organizations should verify if the component is in use and either remove it or implement compensating controls such as strict role-based access constraints, network isolation, and enhanced monitoring of authenticated sessions.

Recommended fix High confidence
  1. Migrate away from Apache UIMA DUCC to a supported alternative, as the module is retired and will not receive security patches.
  2. If migration is not immediately possible, implement network isolation by placing the DUCC component in a dedicated, firewalled network segment with minimal exposure.
  3. Restrict administrative access to only highly trusted individuals; implement strong authentication mechanisms.
  4. Implement additional application-level monitoring and logging for the DUCC component to detect any anomalous activity.
  5. Consider deploying intrusion detection/prevention systems (IDS/IPS) to monitor for attempts to exploit command injection vulnerabilities.
  6. Review and minimize any user permissions related to modifying core entities, as this is the attack vector described.
Caveat Migration away from this retired/end-of-life component will likely require significant application redesign and testing; there is no direct upgrade path to a fixed version.
