Identify the affected asset

Confirm whether Apache Software Foundation Apache HTTP Server, JBoss Core Services for RHEL 8, JBoss Core Services on RHEL 7 is installed, record the deployed version and installation path, and identify exposed interfaces.

  • Record the product name, package or appliance identifier, and installed version.
  • Identify internet-facing, administrative, API, and internal access paths.
  • Preserve the pre-change configuration and relevant service logs.
02

Validate the affected-version match

Compare the deployed version with the affected range: >= 2.4.17 <= 2.4.67, >= 2.4.17 < 2.4.68, 11.0. Treat incomplete inventory results as unresolved.

03

  • Run a functional health check for critical service paths.
  • Review authentication, error, application, and security monitoring logs.
  • Reassess exposure if the supported fix cannot be applied.
