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
OpenShift haproxy cartridge: predictable /tmp in set-proxy connection hook which could facilitate DoS

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 · moderate confidence

The OpenShift haproxy cartridge's set-proxy connection hook uses predictable filenames in /tmp, allowing an attacker to potentially interfere with or disrupt the proxy connection setup, leading to a denial of service condition.

MitigationModify the set-proxy connection hook to use unpredictable file paths (e.g., via mktemp or UUID-based naming) instead of predictable /tmp filenames.

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 OpenShift version
    Run 'oo-version' or check /etc/openshift/env/OPENSHIFT_VERSION if available, or look for version file in the OpenShift installation directory
    Affected if Version is 1.0 or 2.0 (exact match)
  2. Locate haproxy cartridge installation
    Find the haproxy cartridge directory - typically in /usr/lib/openshift/cartridges/haproxy or /var/lib/openshift/cartridges/haproxy
    Affected if haproxy cartridge is installed on the system
  3. Inspect set-proxy connection hook
    Locate the set-proxy script within the haproxy cartridge - look for files named set-proxy, proxy, or connection-related hooks in the cartridge's bin or hooks directory
    Affected if The script exists and uses hardcoded/predictable filenames in /tmp instead of mktemp or UUID-based naming
  4. Check /tmp for predictable haproxy files
    List files in /tmp directory and look for any haproxy-related files with predictable naming patterns (e.g., sequential or static filenames)
    Affected if Files matching predictable patterns exist in /tmp related to haproxy proxy setup
  5. Verify hook execution context
    Examine how the set-proxy hook is invoked - check if it's triggered during connection setup for applications using the haproxy cartridge
    Affected if Applications are configured to use the haproxy cartridge with connection hooks enabled

Environment is affected if running OpenShift version 1.0 or 2.0 with the haproxy cartridge installed and the set-proxy hook uses predictable /tmp filenames.
