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
In SAP BusinessObjects Business Intelligence Platform (Web Services) - versions 420, 430, an attacker can control a malicious BOE server, forcing the application server to connect to its own admintools, leading to a high impact on availability.

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 Web Services (versions 420, 430). An attacker can control a malicious BOE server and trick the application server into connecting to it, which then forces connections to the application's own admintools, causing denial of service and high availability impact.

MitigationApply the relevant SAP security patch for CVE-2023-27271 immediately. In the interim, restrict network-level access to the BusinessObjects server and monitor for suspicious outbound connection attempts to untrusted BOE servers.

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 installed BusinessObjects BI Platform version
    Check the SAP BusinessObjects installation directory for version information, typically found in the installer logs or by querying the SAP BusinessObjects Central Management Console (CMC) about system information. On Windows, this may also appear in Add/Remove Programs.
    Affected if The installed version is exactly 420 or exactly 430.
  2. Verify Web Services component is enabled
    Access the SAP BusinessObjects CMC and navigate to the Web Services or Enterprise service configuration area. Check if the 'BI Platform Web Services' or 'RESTful Web Services' are currently enabled.
    Affected if Web Services are enabled and accessible on the network.
  3. Review outbound network access rules
    Inspect the firewall or network security groups protecting the BusinessObjects server. Look for rules that allow outbound TCP connections from the BusinessObjects server to other BOE servers on ports used by Web Services (typically 8080, 8443, or custom ports).
    Affected if The server permits unrestricted outbound connections to other BOE servers on Web Service ports.
  4. Monitor for suspicious outbound connections
    Use network monitoring tools or review server logs for outbound connection attempts from the BusinessObjects server to unfamiliar or untrusted BOE server addresses, especially connections occurring without legitimate administrative action.
    Affected if Outbound connections to untrusted or unknown BOE servers are observed in logs or network traffic.

You are affected if your SAP BusinessObjects BI Platform is version 420 or 430, the Web Services component is enabled, and the server can make outbound connections to potentially malicious BOE servers.
