CVE-2025-42962 is a medium-severity cross-site scripting (XSS) vulnerability classified under CWE-79, affecting SAP Business Warehouse's Business Explorer Web 3.5 loading animation component. This vulnerability arises due to improper neutralization of input during web page generation, allowing an attacker to craft a malicious link containing injected script code. When an authenticated user clicks this link, the injected script executes within the user's browser context, leveraging the victim's session and privileges within the SAP Business Warehouse environment. The vulnerability affects multiple versions of SAP Business Warehouse and its DW4CORE components, including versions 730 through 758 and DW4CORE 100 through 916. The CVSS 3.1 base score is 6.1, indicating a medium severity level. The attack vector is network-based (AV:N), requiring no privileges (PR:N), but user interaction is necessary (UI:R). The scope is changed (S:C), meaning the vulnerability affects resources beyond the initially vulnerable component. The impact affects confidentiality and integrity but does not impact availability. Specifically, an attacker could steal sensitive data accessible to the victim or manipulate data displayed within the SAP Business Warehouse interface. There are no known exploits in the wild yet, and no patches are currently linked, suggesting that organizations should prioritize monitoring and mitigation. The vulnerability's exploitation requires an authenticated user to click a malicious link, which could be delivered via phishing or social engineering. Given SAP Business Warehouse's role in enterprise data analytics and reporting, exploitation could lead to unauthorized data disclosure or manipulation, undermining trust in business intelligence outputs.

For European organizations, the impact of CVE-2025-42962 can be significant due to the widespread use of SAP Business Warehouse in large enterprises and public sector entities. Confidentiality breaches could expose sensitive business intelligence data, including financial reports, strategic plans, and operational metrics. Integrity compromises could result in corrupted or falsified reports, leading to poor decision-making or regulatory non-compliance. Although availability is not affected, the loss of data trustworthiness can disrupt business operations and damage reputations. In regulated sectors such as finance, healthcare, and critical infrastructure, unauthorized data disclosure or manipulation could lead to legal penalties under GDPR and other compliance frameworks. The requirement for user interaction means phishing campaigns targeting SAP BW users could be an effective attack vector, increasing risk. Additionally, the scope change in the vulnerability indicates that the impact could extend beyond the immediate component, potentially affecting other integrated SAP modules or connected systems. Overall, European organizations relying on SAP BW for critical analytics should consider this vulnerability a moderate risk that requires timely mitigation to prevent data breaches and integrity issues.

To mitigate CVE-2025-42962, European organizations should implement the following specific measures: 1) Apply SAP security patches promptly once available, as SAP regularly releases security notes addressing such vulnerabilities. 2) Implement strict input validation and output encoding on all user-supplied data within SAP Business Warehouse customizations to prevent script injection. 3) Educate users about phishing risks, emphasizing caution when clicking links, especially those received via email or messaging platforms. 4) Employ web application firewalls (WAFs) with rules tailored to detect and block XSS payloads targeting SAP BW endpoints. 5) Restrict SAP BW user privileges to the minimum necessary, reducing the impact of a compromised session. 6) Monitor SAP BW logs and network traffic for anomalous activities indicative of exploitation attempts. 7) Consider deploying Content Security Policy (CSP) headers to limit the execution of unauthorized scripts in the SAP BW web interface. 8) Conduct regular security assessments and penetration testing focused on SAP BW components to identify and remediate injection flaws proactively. These targeted actions go beyond generic advice by focusing on SAP BW-specific controls and user behavior.
