DescriptionCVE.org

SAP NetWeaver Application Server Java allows an unauthenticated attacker to inject malicious JavaScript through crafted URLs. When a victim accesses such a URL, the script executes in the user's browser, allowing the attacker to access sensitive session information and modify non-sensitive data displayed in the client�s browser. This results in a high impact on confidentiality, low impact on integrity with no impact on availability of the application.

AnalysisAI

Reflected cross-site scripting in SAP NetWeaver Application Server Java (specifically the Configuration Wizard component) lets an unauthenticated attacker embed malicious JavaScript in crafted URLs that executes in a victim's browser when the link is opened. Because the CVSS scope is changed (S:C) and confidentiality impact is high, a successful lure can expose sensitive session information and tamper with non-sensitive data rendered in the client. …

Vulnerability AssessmentAI

Exploitation Exploitation requires the attacker to deliver a crafted URL targeting the SAP NetWeaver AS Java Configuration Wizard component and a victim to actively open that URL in a browser (CVSS UI:R - required user interaction is the primary limiting factor). … Additional conditions and limiting factors are described in the full assessment.
Risk Assessment The CVSS 3.1 base score is 8.2 (High) with vector AV:N/AC:L/PR:N/UI:R/S:C/C:H/I:L/A:N: network-reachable, low complexity, no privileges, but requiring user interaction (a victim must open the crafted URL). … Full risk analysis with EPSS, KEV, and SSVC signal comparison available after sign-in.
Exploit Scenario An attacker crafts a URL targeting a victim organization's internet-facing SAP NetWeaver AS Java Configuration Wizard endpoint, embedding malicious JavaScript in a reflected parameter, and delivers it via phishing email or chat to an SAP administrator or user. When the victim clicks the link, the script runs in their authenticated SAP browser session, exfiltrating session information and manipulating displayed data. …
Remediation Apply the fix from SAP Security Note 3748227 (https://me.sap.com/notes/3748227), released as part of SAP Security Patch Day (https://url.sap/sapsecuritypatchday); the input does not specify an exact patched version, so confirm the precise SP/patch level directly in the SAP Note before deployment. … Detailed patch versions, workarounds, and compensating controls in full report.
