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
SAP Host Agent, version 7.21, allows an unprivileged user to read the shared memory or write to the shared memory by sending request to the main SAPOSCOL process and receive responses that may contain data read with user root privileges e.g. size of any directory, system hardware and OS details, leading to Missing Authorization Check vulnerability.

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 · high confidence

Missing authorization check in SAP Host Agent 7.21 allows unprivileged users to send requests directly to the SAPOSCOL process, enabling read/write access to shared memory. This exposes system information (directory sizes, hardware details, OS configuration) that is retrieved using root privileges, giving unauthorized users access to sensitive system data.

MitigationApply the relevant SAP security patch for CVE-2020-6183 to upgrade SAP Host Agent to a version with proper authorization controls on the SAPOSCOL shared memory interface.

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 Host Agent installation
    Check if SAP Host Agent is installed by looking for its executables or service. On Unix/Linux: `which saposcol` or check `/usr/sap/hostctrl/exe/saposcol`. On Windows: check service 'SAP Host Agent' in services.msc or look in `C:\Program Files\sap\hostctrl\exe\saposcol.exe`.
    Affected if SAP Host Agent is installed and version is exactly 7.21
  2. Confirm SAP Host Agent version
    Run `sapHostCtrl -version` or `/usr/sap/hostctrl/exe/sapHostCtrl -version` to display the installed version number.
    Affected if Version displayed is exactly 7.21
  3. Check if SAPOSCOL process is running
    On Unix/Linux: run `ps -ef | grep saposcol`. On Windows: check process 'saposcol.exe' in Task Manager or via `tasklist | findstr saposcol`.
    Affected if SAPOSCOL process is running on a system with SAP Host Agent version 7.21
  4. Inspect shared memory authorization
    This requires examining the SAPOSCOL configuration and authorization settings. Check for proper ACLs or permission controls on the shared memory segments used by SAPOSCOL (typically visible via `ipcs -m` on Unix systems). Unrestricted access indicates the vulnerability is present.
    Affected if Unprivileged users can access SAPOSCOL shared memory without authorization checks

System is affected if SAP Host Agent version 7.21 is installed AND the SAPOSCOL process is running with unrestricted access to shared memory interfaces.
