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 (SAPOSCOL) - version 7.22, allows an unauthenticated attacker with network access to a server port assigned to the SAP Start Service to submit a crafted request which results in a memory corruption error. This error can be used to reveal but not modify any technical information about the server. It can also make a particular service temporarily unavailable

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

Memory corruption vulnerability in SAP Host Agent (SAPOSCOL) version 7.22 where an unauthenticated attacker with network access to the SAP Start Service port can submit crafted requests causing memory corruption. This enables disclosure of technical server information and potential temporary service unavailability, but does not allow modification of data.

MitigationRestrict network access to SAP Start Service ports via firewall rules or network segmentation, and apply the relevant SAP security patch when available.

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. Identify if SAP Host Agent is installed
    Check for SAP Host Agent installation by looking for the saposcol executable or SAP Host Agent service. On Windows, check Services for 'SAP Host Agent'. On Unix/Linux, check for /usr/sap/hostctrl/exe/saposcol or similar paths.
    Affected if SAP Host Agent is not installed on the system.
  2. Determine the installed SAP Host Agent version
    Execute: saposcol -v or /usr/sap/hostctrl/exe/saposcol -v to retrieve the version number. Alternatively, check the SAP Host Agent service details or version file in the installation directory.
    Affected if The version is not 7.22 - versions other than 7.22 are not affected by this specific CVE.
  3. Verify SAP Start Service port accessibility
    Identify the SAP Start Service port (typically 5XX13 or 5XX14 where XX is the SAP system number) using SAP configuration. Check if this port is listening on network interfaces accessible from untrusted networks using netstat or similar tools.
    Affected if The SAP Start Service port is exposed to untrusted/unauthenticated network access.
  4. Confirm SAPOSCOL process is running
    Check if the saposcol process is active. On Windows, use Task Manager or sc query. On Unix/Linux, use ps -ef | grep saposcol.
    Affected if SAPOSCOL is not running - the vulnerability requires the service to be active to be exploitable.

The system is affected if SAP Host Agent version 7.22 is installed AND the SAP Start Service port is network-accessible to unauthenticated attackers.

Mitigation available No clean upgrade yet — mitigate in the meantime
Mitigation

Restrict network access to SAP Start Service ports via firewall rules or network segmentation, and apply the relevant SAP security patch when available.

Recommended fix Moderate confidence

SAP Host Agent version higher than 7.22 (refer to SAP Security Note for exact version)

  1. Check current SAP Host Agent version using 'sapcontrol -nr <instance> -function GetVersion' or '/usr/sap/hostctrl/exe/saposcol -v'
  2. Review SAP Security Notes for CVE-2023-27498 on SAP Support Portal (launchpad.support.sap.com) to obtain the specific patch or updated version
  3. Download and apply the updated SAP Host Agent package from the SAP Software Download Center
  4. Restart SAP Host Agent service using 'sapcontrol -nr <instance> -function RestartService'
  5. Verify the fix by checking the version and testing the previously vulnerable functionality
Caveat Review SAP Host Agent release notes for any changes in functionality or configuration requirements before upgrading
