CVE-2026-44762: SAP Data Services Console XSS Vulnerability

CVE-2026-44762 Overview

CVE-2026-44762 affects the SAP Data Services Management Console. The application ships with an overly permissive Content Security Policy (CSP) and lacks specific restrictive directives. An authenticated attacker can chain this weakness with a separate injection vulnerability to execute malicious scripts within the application's context. The issue is categorized under [CWE-1021: Improper Restriction of Rendered UI Layers or Frames]. Successful exploitation results in limited impact to confidentiality and integrity, with no impact on availability. Exploitation requires low privileges, user interaction, and a high attack complexity, which reduces practical risk. The vulnerability was published to the National Vulnerability Database on 2026-08-11.

Critical Impact
An authenticated user can chain this CSP weakness with a secondary injection flaw to run scripts in the application's origin, exposing session data and enabling limited integrity violations.

Technical Details for CVE-2026-44762

Vulnerability Analysis

The SAP Data Services Management Console serves web content with a Content Security Policy that fails to constrain script sources, frame ancestors, and related directives adequately. CSP is a browser-enforced defense layer that restricts which script, style, and frame sources a page can load. When the policy is permissive, the browser accepts content that a stricter policy would block.

On its own, this misconfiguration does not grant code execution. It becomes exploitable when paired with an injection primitive elsewhere in the application. In that scenario, the browser executes attacker-controlled JavaScript within the trust boundary of the Management Console.

The CWE-1021 mapping reflects the missing directives that would otherwise limit framing and script origins. The EPSS data places exploitation probability in the low range, consistent with the requirement for chaining and user interaction.

Root Cause

The root cause is a defense-in-depth control gap. The Management Console emits response headers that either omit Content-Security-Policy directives such as script-src, frame-ancestors, and object-src, or set them to values that permit inline scripts and broad source lists. The absence of these directives removes a browser-side barrier against script injection.

Attack Vector

An authenticated attacker with low privileges targets an interactive user session on the Management Console. The attacker delivers a crafted input or link that triggers a companion injection flaw. Because CSP does not block the injected payload, the browser evaluates the script under the console's origin. The payload can read session tokens, alter displayed data, or perform actions on behalf of the victim.

The attack requires user interaction and high complexity, meaning the attacker must satisfy specific preconditions to succeed. Refer to SAP Note #3739913 and SAP Security Patch Day for authoritative technical details.

Detection Methods for CVE-2026-44762

Indicators of Compromise

Unexpected outbound HTTP requests from browsers that have the Management Console open, pointing to unfamiliar domains
Console audit log entries showing configuration or job changes originating from user sessions without corresponding user activity
HTTP responses from the Management Console lacking Content-Security-Policy headers or containing unsafe-inline and wildcard source values

Detection Strategies

Inspect HTTP response headers from Management Console endpoints and flag responses that omit script-src, frame-ancestors, or object-src directives
Correlate authenticated session activity with browser-side telemetry to identify script execution that does not match legitimate console workflows
Review web proxy logs for cross-origin script loads referred by Management Console pages

Monitoring Recommendations

Enable verbose access and audit logging on the SAP Data Services Management Console and forward events to a central analytics platform
Alert on modifications to CSP configuration files or reverse proxy header rewrites in front of the console
Track authentication events for accounts with access to the Management Console and baseline normal session patterns

How to Mitigate CVE-2026-44762

Immediate Actions Required

Apply the SAP-supplied patch referenced in SAP Note #3739913 as soon as the change window permits
Restrict network access to the Management Console to trusted administrative networks only
Review and reduce the population of accounts authorized to sign in to the Management Console

Patch Information

SAP published the fix through SAP Note #3739913, released as part of SAP Security Patch Day. The patch introduces restrictive CSP directives on Management Console responses. Administrators must authenticate to the SAP support portal to download the note and follow the version-specific installation instructions.

Workarounds

Place the Management Console behind a reverse proxy that injects a strict Content-Security-Policy header with explicit script-src, frame-ancestors 'none', and object-src 'none' directives
Enforce short session timeouts and require re-authentication for sensitive administrative actions in the console
Disable or block browser access to the Management Console for users who do not require it

bash

# Example reverse proxy header injection (nginx)
add_header Content-Security-Policy "default-src 'self'; script-src 'self'; object-src 'none'; frame-ancestors 'none'; base-uri 'self'" always;
add_header X-Frame-Options "DENY" always;
