CVE-2026-76968: SAP Web Dispatcher Information Disclosure

CVE-2026-76968 Overview

CVE-2026-76968 is an information disclosure vulnerability affecting SAP Web Dispatcher, Internet Communication Manager (ICM), and SAP Content Server. An authenticated low-privileged attacker can reach an administrative function or interface exposed by these components and retrieve sensitive information about the system state. The disclosed data can support follow-on attacks against the affected SAP landscape.

The issue is tracked under CWE-497: Exposure of Sensitive System Information to an Unauthorized Control Sphere. It impacts confidentiality only, with no impact on integrity or availability.

Critical Impact
An authenticated attacker with low privileges can obtain sensitive system state information from SAP Web Dispatcher, ICM, or Content Server over the network, enabling reconnaissance for further attacks.

Technical Details for CVE-2026-76968

Vulnerability Analysis

SAP Web Dispatcher and the Internet Communication Manager function as HTTP(S) entry points into SAP application servers. SAP Content Server stores and serves unstructured content such as documents and attachments. All three components expose administrative interfaces used for status monitoring, configuration, and operations.

CVE-2026-76968 allows an authenticated user with low privileges to reach one of these administrative endpoints and read information that should be restricted to administrators. The returned data describes the internal state of the system, which can include configuration data, runtime parameters, or diagnostic output. Attackers use this class of information to map the environment, identify weak configurations, and select follow-on techniques.

Root Cause

The root cause is insufficient authorization enforcement on administrative functionality, categorized as [CWE-497]. The affected interface accepts requests from any authenticated principal rather than verifying that the caller holds administrative privileges before returning sensitive system state.

Attack Vector

The vulnerability is exploitable over the network. The attacker must first authenticate to the SAP component with any valid low-privilege account. After authentication, the attacker issues an HTTP request to the administrative function or interface exposed by SAP Web Dispatcher, ICM, or Content Server. The server returns sensitive system information in the response.

Exploitation requires no user interaction and no elevated privileges. No public proof-of-concept or in-the-wild exploitation has been reported for this identifier. Refer to SAP Note #3750721 for the vendor's technical description.

Detection Methods for CVE-2026-76968

Indicators of Compromise

HTTP requests from non-administrative user accounts to administrative URL paths on SAP Web Dispatcher, ICM, or Content Server.
Successful responses containing configuration data, environment variables, or runtime state returned to low-privilege sessions.
Repeated enumeration of admin endpoints from a single authenticated session or source IP within a short window.

Detection Strategies

Enable and forward SAP Web Dispatcher and ICM access logs, then alert on 2xx responses to admin paths originating from users without administrative roles.
Correlate SAP Content Server access logs with identity data to identify low-privileged accounts accessing management functions.
Baseline normal administrative access patterns and flag deviations, particularly from service accounts or interactive users that do not typically call admin URLs.

Monitoring Recommendations

Ingest SAP application, ICM, and Web Dispatcher logs into a centralized SIEM for cross-source correlation with identity events.
Monitor for unusual outbound reuse of information disclosed via admin endpoints, such as credentials or internal hostnames appearing in later attack stages.
Track authentication events tied to low-privilege accounts that suddenly begin probing administrative interfaces.

How to Mitigate CVE-2026-76968

Immediate Actions Required

Apply the fix described in SAP Note #3750721 to all affected SAP Web Dispatcher, Internet Communication Manager, and SAP Content Server instances.
Review SAP Security Patch Day guidance at the SAP Security Patch Day portal and prioritize deployment during the next maintenance window.
Audit user and service accounts that hold logon rights to the affected components and remove unnecessary access.

Patch Information

SAP has published the corrective note as SAP Note #3750721. Administrators must authenticate to the SAP ONE Support Launchpad to download the note, identify the fixed Support Package or kernel patch level for their deployed release, and apply the update following standard SAP change management procedures.

Workarounds

Restrict network reachability of SAP Web Dispatcher, ICM, and Content Server administrative endpoints to trusted management networks using firewall rules or reverse proxy access control lists.
Disable administrative interfaces on Internet-facing Web Dispatcher instances when not required for operations.
Enforce least-privilege authorization for all SAP users and remove standing access from accounts that do not require administrative capability.
