CVE-2025-42988 Overview
CVE-2025-42988 is an information disclosure vulnerability in the SAP BusinessObjects Business Intelligence Platform. Under specific conditions, an unauthenticated remote attacker can send specially crafted HTTP requests to enumerate HTTP endpoints on the internal network. The flaw is classified as Server-Side Request Forgery [CWE-918] and can be leveraged to further develop SSRF attacks against internal infrastructure. The issue affects the confidentiality of the application but does not impact integrity or availability.
Critical Impact
Unauthenticated network attackers can enumerate internal HTTP endpoints reachable from the SAP BusinessObjects host, exposing internal network topology and enabling follow-on SSRF exploitation.

Technical Details for CVE-2025-42988
Vulnerability Analysis
The vulnerability resides in how SAP BusinessObjects Business Intelligence Platform processes attacker-influenced HTTP request parameters. An unauthenticated attacker crafts HTTP requests that cause the server to reach out to attacker-specified URLs. The server's behavior when handling internal targets discloses information about which endpoints exist on the internal network. This forms the reconnaissance primitive of a classic Server-Side Request Forgery [CWE-918] flaw.
While the current CVE scope limits impact to confidentiality only, attackers can chain this information disclosure with later SSRF techniques to interact with unexposed internal services. Targets typically include cloud metadata services, internal admin interfaces, and adjacent SAP components. The vulnerability requires no privileges and no user interaction, making it broadly exploitable over the network.
Root Cause
The root cause is insufficient validation of destination URLs or host parameters used by server-side HTTP client functionality in the BusinessObjects platform. The application does not restrict outbound HTTP requests to a safe allowlist. Differential responses, timing, or status codes returned to the requester reveal whether internal endpoints are reachable.
Attack Vector
Attack traffic originates from the public network against exposed BusinessObjects HTTP interfaces. The attacker submits crafted HTTP requests referencing internal hostnames or IP addresses. The server processes these requests and returns responses that disclose endpoint reachability. No authentication or user interaction is required for exploitation.
No verified public proof-of-concept code is available. Refer to the SAP Note #3585545 for vendor technical details.
Detection Methods for CVE-2025-42988
Indicators of Compromise
- Outbound HTTP connections from the BusinessObjects application server to internal IP ranges or hostnames not part of normal application workflows.
- Repeated inbound HTTP requests containing URL, host, or address parameters referencing RFC1918 addresses, localhost, 127.0.0.1, or cloud metadata endpoints such as 169.254.169.254.
- Anomalous spikes in server-generated requests targeting varied internal ports (80, 443, 8080, 8443, 9000).
Detection Strategies
- Inspect web server and reverse proxy logs for crafted request patterns that include internal URLs or IPs in query strings, headers, or POST bodies.
- Correlate inbound requests against outbound HTTP egress from the BusinessObjects host to identify SSRF-style relays.
- Deploy WAF signatures targeting SSRF payloads and monitor for elevated block or alert rates on BusinessObjects endpoints.
Monitoring Recommendations
- Enable verbose HTTP access logging on all BusinessObjects front-end and application tiers and forward logs to a centralized analytics platform.
- Monitor DNS resolution requests from the BusinessObjects host for unusual internal or metadata hostnames.
- Alert on any outbound connection from BusinessObjects to cloud metadata IPs or unexpected internal management interfaces.
How to Mitigate CVE-2025-42988
Immediate Actions Required
- Apply the fix documented in SAP Note #3585545 to all affected BusinessObjects Business Intelligence Platform installations.
- Review the SAP Security Patch Day bulletin and prioritize patching of internet-exposed BusinessObjects instances.
- Restrict inbound network access to BusinessObjects HTTP interfaces to trusted networks and authenticated users where operationally feasible.
Patch Information
SAP has published remediation guidance in SAP Note #3585545, released as part of the SAP Security Patch Day cycle. Customers must authenticate to the SAP Support Portal to obtain the corrective package and apply it according to their BusinessObjects release track (430, 2025, or 2027 Enterprise).
Workarounds
- Place BusinessObjects behind a reverse proxy or WAF that strips or validates parameters carrying URL or host values.
- Enforce egress firewall rules on the BusinessObjects host that deny outbound HTTP traffic to internal management subnets and cloud metadata addresses.
- Segment the BusinessObjects application tier so it cannot initiate connections to sensitive internal services beyond its documented dependencies.
