Summary
Applications based on SAP GUI for HTML in SAP NetWeaver Application Server ABAP do not sufficiently sanitize user-supplied content, allowing an authenticated attacker to send malicious content to another user. If the victim interacts with the affected content, malicious scripts could be executed in the victim's browser context. This vulnerability has a low impact on confidentiality and integrity and no impact on availability.
Risk Assessment
The risk involves potential execution of malicious scripts in an authenticated user's browser, possibly leading to unauthorized data access or modification. The impact on the organization is limited but could undermine system trust.
Recommendation
Apply SAP-provided patches and implement server-side content sanitization. Also educate users about the risks of interacting with suspicious content.
Other vulnerabilities in SAP NetWeaver Application Server ABAP
See all- CVE-2026-34265Critical
SAP NetWeaver Application Server ABAP is vulnerable to logical errors in DIAG protocol parsing, allowing an unauthenticated attacker to cause memory corruption. This could potentially disclose sensitive system information or crash the system, leading to high impact on confidentiality, integrity, and availability.
- CVE-2026-44747Critical
An authenticated attacker can exploit logical errors in memory management in SAP NetWeaver Application Server ABAP, causing memory corruption. This could lead to unauthorized data access, modification, or system unavailability.
- CVE-2026-44748Critical
SAP NetWeaver Application Server ABAP and ABAP Platform allow an authenticated attacker with normal privileges to obtain a valid signed message and send modified signed XML documents to the verifier. This may result in acceptance of tampered identity information, leading to unauthorized access to sensitive user data and potential disruption of normal system usage.
- CVE-2026-66779Medium
Cross-Site Scripting (XSS) vulnerability in SAP NetWeaver Application Server ABAP. An authenticated attacker can create a malicious link and make it publicly accessible. When an authenticated victim clicks the link, the injected input is processed and reflected in the DOM on the client side, leading to execution of malicious content in the victim's browser.
- CVE-2026-44760Medium
A Cross-Site Scripting (XSS) vulnerability in the Business Server Pages framework of SAP NetWeaver Application Server ABAP reflects unsanitized input into HTTP responses, allowing an attacker to inject and execute arbitrary JavaScript code.
