CVE-2026-24327: SAP SEM Information Disclosure Vulnerability

CVE-2026-24327 Overview

CVE-2026-24327 is a Missing Authorization vulnerability affecting SAP Strategic Enterprise Management (Balanced Scorecard in Business Server Pages). Due to a missing authorization check, an authenticated attacker could access information that they are otherwise unauthorized to view. This vulnerability results in low impact on confidentiality with no effect on integrity or availability.

Critical Impact

Authenticated attackers can bypass authorization controls to access sensitive business scorecard data in SAP Strategic Enterprise Management environments.

Affected Products

• SAP Strategic Enterprise Management
• Balanced Scorecard in Business Server Pages (BSP)

Technical Details for CVE-2026-24327

Vulnerability Analysis

This vulnerability is classified under CWE-862 (Missing Authorization), which occurs when the software does not perform an authorization check when an actor attempts to access a resource or perform an action. In the context of SAP Strategic Enterprise Management's Balanced Scorecard module, the application fails to validate whether an authenticated user has the necessary permissions before granting access to specific data or functionality.

The vulnerability is exploitable over the network and requires low attack complexity, though the attacker must have valid authentication credentials to the SAP system. Once authenticated, the attacker can leverage the missing authorization check to view information beyond their authorized scope.

Root Cause

The root cause of CVE-2026-24327 is a missing authorization check in the Business Server Pages (BSP) component of SAP Strategic Enterprise Management's Balanced Scorecard functionality. The application accepts authenticated user requests and processes them without properly verifying whether the user has the appropriate authorization level to access the requested data.

This is a common issue in enterprise applications where authentication is properly implemented, but granular authorization checks are inadvertently omitted from specific code paths or modules.

Attack Vector

The attack vector for this vulnerability is network-based. An attacker who has obtained valid credentials to the SAP system (either through legitimate access or credential compromise) can exploit this vulnerability by:

1. Authenticating to the SAP Strategic Enterprise Management system
2. Navigating to or directly requesting Balanced Scorecard functionality
3. Accessing business intelligence data that should be restricted based on the user's authorization level

The exploitation does not require user interaction and operates within the unchanged security scope of the vulnerable component. The vulnerability primarily impacts confidentiality by exposing unauthorized information to authenticated users.

Detection Methods for CVE-2026-24327

Indicators of Compromise

• Unusual access patterns to Balanced Scorecard reports by users who typically do not use this functionality
• Anomalous data requests to SAP Strategic Enterprise Management modules from authenticated user sessions
• Audit log entries showing access to scorecard data by users without appropriate authorization profiles

Detection Strategies

• Enable and monitor SAP Security Audit Log (SAL) for unauthorized access attempts to SEM-BCS transactions
• Implement authorization trace logging to detect access attempts that bypass expected permission checks
• Deploy SentinelOne Singularity to monitor SAP application servers for suspicious activity patterns
• Configure alerts for users accessing Balanced Scorecard data outside their normal operational scope

Monitoring Recommendations

• Review SAP authorization logs regularly for evidence of users accessing SEM-BSC data without proper authorization objects
• Monitor network traffic to SAP servers for anomalous patterns targeting the BSP application layer
• Establish baseline access patterns for Balanced Scorecard functionality and alert on deviations

How to Mitigate CVE-2026-24327

Immediate Actions Required

• Review and apply the security patch detailed in SAP Note #3680390
• Audit current user authorizations for SAP Strategic Enterprise Management and Balanced Scorecard access
• Review access logs to identify any potential exploitation prior to patching
• Implement additional authorization checks at the application layer if patching must be delayed

Patch Information

SAP has released a security patch to address this vulnerability. Organizations should apply the fix documented in SAP Note #3680390. Additional information is available through the SAP Security Patch Day Update.

The patch implements proper authorization checks in the Balanced Scorecard BSP component to ensure users can only access data appropriate to their assigned authorization profiles.

Workarounds

• Restrict access to SAP Strategic Enterprise Management Balanced Scorecard functionality to only essential users until the patch can be applied
• Implement network-level access controls to limit which systems and users can reach the affected BSP components
• Enable enhanced logging and monitoring to detect potential exploitation attempts
• Review and tighten existing SAP authorization roles for SEM-BCS access
