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
IBM InfoSphere Information Server 11.7.0.0 through 11.7.1.6 is vulnerable to HTTP header injection, caused by improper validation of input by the HOST headers. This could allow an attacker to conduct various attacks against the vulnerable system, including cross-site scripting, cache poisoning or session hijacking.

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

IBM InfoSphere Information Server versions 11.7.0.0 through 11.7.1.6 contains an HTTP header injection vulnerability due to improper validation of HOST header input. An attacker can inject malicious headers via the HOST field to conduct cross-site scripting attacks, poison web caches, or hijack user sessions.

MitigationApply the vendor patch or upgrade to a version beyond 11.7.1.6. As a compensating control, implement web application firewall rules or reverse proxy validation to sanitize HOST header values before processing.

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. Confirm IBM InfoSphere Information Server is installed
    Locate the product installation directory or check installed programs on the system. Common paths include /opt/IBM/InformationServer or C:\IBM\InformationServer on Windows.
    Affected if The product is present on the system
  2. Determine the installed version number
    Check the product version via its built-in version utility, About dialog in the management console, or look for version files in the installation directory.
    Affected if The installed version is 11.7.0.0 through 11.7.1.6 (inclusive)
  3. Verify the web application server component is running
    Check if the IBM InfoSphere web interface or IBM WebSphere Application Server component that hosts it is active. Look for processes like was or check service status.
    Affected if The HTTP/web interface is accessible and the product version is within the affected range
  4. Inspect Host header handling configuration
    Review the web server or proxy configuration files (such as httpd.conf, plugin-cfg.xml, or IBM WebSphere configuration) to see if there are rules validating or sanitizing the Host header value.
    Affected if No Host header validation is configured and the version is within the affected range

You are affected if IBM InfoSphere Information Server version 11.7.0.0 through 11.7.1.6 is installed with its web interface enabled and no Host header validation is configured.

Generated from the published advisory. Verify against your own configuration.

Upgrade available Upgrade to a release after 11.7.1.6
Interim mitigation

Apply the vendor patch or upgrade to a version beyond 11.7.1.6. As a compensating control, implement web application firewall rules or reverse proxy validation to sanitize HOST header values before processing.

Recommended fix Moderate confidence

IBM InfoSphere Information Server 11.7.1.7 or later

  1. 1. Determine the current installed version of IBM InfoSphere Information Server by checking the installation or consulting IBM documentation.
  2. 2. Download IBM InfoSphere Information Server version 11.7.1.7 or later from IBM Fix Central (https://www.ibm.com/support/fixcentral/).
  3. 3. Review the IBM installation and upgrade instructions for InfoSphere Information Server before proceeding.
  4. 4. Back up the current installation, including all configurations, databases, and metadata repositories.
  5. 5. Stop all IBM InfoSphere Information Server services and processes.
  6. 6. Install the upgraded version (11.7.1.7 or later) following IBM's documented upgrade procedures.
  7. 7. After installation, verify that all services start correctly.
  8. 8. Test critical workflows to ensure the upgrade did not break existing functionality.
