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 BusinessObjects Business Intelligence Platform (Web Services) - versions 420, 430, allows an attacker to inject arbitrary values as CMS parameters to perform lookups on the internal network which is otherwise not accessible externally. On successful exploitation, attacker can scan internal network to determine internal infrastructure for further attacks like remote file inclusion, retrieve server files, bypass firewall and force the vulnerable server to execute malicious requests, resulting in sensitive information disclosure. This causes limited impact on confidentiality of data.

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

This is a Server-Side Request Forgery (SSRF) vulnerability in SAP BusinessObjects BI Platform's Web Services component. Attackers can inject arbitrary values as CMS parameters to force the server to perform lookups on internal network resources that would otherwise be inaccessible. This enables internal network reconnaissance, potential remote file inclusion, file retrieval, and firewall bypass for further attacks.

MitigationImplement strict input validation and sanitization for CMS parameters to prevent arbitrary value injection. Additionally, apply network segmentation and firewall rules to restrict the server's ability to make arbitrary network connections, limiting the impact of SSRF attacks.

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 SAP BusinessObjects BI Platform version
    Use SAP administration tools or system information utilities to determine the installed version of SAP BusinessObjects Business Intelligence
    Affected if Installed version is 420 or 430
  2. Confirm Web Services component is enabled
    Verify that the Web Services component is accessible and operational on the SAP BusinessObjects server
    Affected if Web Services component is enabled and reachable
  3. Inspect CMS parameter handling
    Review the CMS configuration and examine how parameters are processed in Web Services requests for potential lack of input validation
    Affected if CMS parameters accept arbitrary values without validation or sanitization
  4. Review network access from server
    Check outbound network access capabilities of the BusinessObjects server to internal network resources
    Affected if Server can make arbitrary network connections to internal systems

Environment is affected if running SAP BusinessObjects BI Platform version 420 or 430 with Web Services enabled and CMS parameters lack input validation, allowing SSRF exploitation.

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

Implement strict input validation and sanitization for CMS parameters to prevent arbitrary value injection. Additionally, apply network segmentation and firewall rules to restrict the server's ability to make arbitrary network connections, limiting the impact of SSRF attacks.

Recommended fix Moderate confidence

SAP BusinessObjects BI Platform 4.2 SP6 or later / 4.3 SP1 or later (specific patch version per SAP Security Note)

  1. 1. Access the SAP Support Portal at https://launchpad.support.sap.com/
  2. 2. Search for the SAP Security Note related to CVE-2023-27894 (SAP Note number should be obtained from SAP)
  3. 3. Download and apply the relevant patch/service pack for SAP BusinessObjects BI Platform 4.2 (version 420) or 4.3 (version 430)
  4. 4. After applying the patch, restart the SIA (Server Intelligence Agent) and CMS services
  5. 5. Verify the fix by reviewing the applied patches in SAP BusinessObjects Central Management Console (CMC) under 'Servers' > 'Server Intelligence Agent'
Caveat Review SAP Security Note for any post-patch configuration changes or additional required actions; test thoroughly in non-production first
