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. Verify SAP IGS installation
    Check for running SAP Internet Graphics Server processes or look for IGS-related services in your SAP system landscape
    Affected if SAP IGS is not installed on the system
  2. Identify installed IGS version
    Use SAP transaction code SM51 to list running SAP instances and their versions, or check the IGS installation directory for version information
    Affected if The installed version matches 7.20, 7.20EXT, 7.45, 7.49, or 7.53 exactly
  3. Confirm IGS is exposed
    Verify that the SAP IGS service is accessible over network ports (typically HTTP/HTTPS ports for the ICM/IGS)
    Affected if IGS is network-accessible without proper access restrictions
  4. Review IGS file handling configuration
    Inspect SAP IGS configuration files for settings related to image file processing and file access permissions
    Affected if IGS is configured to allow external file operations without proper restrictions

You are affected if SAP Internet Graphics Server is installed and the installed version is exactly 7.20, 7.20EXT, 7.45, 7.49, or 7.53 with the service accessible to users
