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 checksWork through these to decide whether this CVE applies to you.
-
Confirm SAP IGS is installedCheck if the Internet Graphics Server component is present in your SAP system. This can typically be verified via SAP transaction code SM51 (Server Processes) or by checking SAP system information. Look for processes named 'IGS' or 'Internet Graphics Server' running on your SAP application servers.Affected if SAP Internet Graphics Server is not installed or not running - not affected by this CVE
-
Identify the IGS versionRetrieve the installed version of the Internet Graphics Server. In SAP systems, this can be done via transaction code SM51 to view system components, or by checking the SAP kernel version. The IGS version is typically reported alongside other SAP kernel component versions.Affected if Unable to determine version - manual verification required to confirm status
-
Compare against affected versionsCompare your identified IGS version against the affected versions: 7.20, 7.20EXT, 7.45, 7.49, and 7.53. If using SAP transaction codes, the version information is usually displayed in the component list.Affected if The installed IGS version exactly matches 7.20, 7.20EXT, 7.45, 7.49, or 7.53 - the environment is affected by this CVE
Your SAP environment is affected if the Internet Graphics Server component is installed and its version is exactly 7.20, 7.20EXT, 7.45, 7.49, or 7.53.
