CVE-2022-41262 is a cross-site scripting (XSS) vulnerability identified in SAP NetWeaver Application Server (AS) for Java, specifically within the HTTP Provider Service component of version 7.50. The root cause of this vulnerability is improper neutralization of input during web page generation (CWE-79), which allows an unauthenticated attacker to inject malicious scripts into web request headers. This occurs due to insufficient input validation and sanitization of HTTP headers processed by the service. Upon successful exploitation, the attacker can execute arbitrary scripts in the context of the affected web application. This can lead to unauthorized viewing or modification of information within the application session, potentially compromising confidentiality and integrity. However, the impact is described as limited, indicating that the vulnerability does not allow full system compromise or widespread data exfiltration. Notably, exploitation does not require authentication, increasing the attack surface, but there are no known exploits in the wild as of the publication date. The vulnerability was reserved on September 21, 2022, and publicly disclosed on December 12, 2022. No official patches or fixes have been linked in the provided information, which may require organizations to apply vendor updates or implement compensating controls. The vulnerability affects a widely used enterprise middleware platform, which is often deployed in complex SAP environments to support business-critical applications and integrations.

For European organizations, the impact of CVE-2022-41262 can be significant in environments where SAP NetWeaver AS for Java 7.50 is deployed, especially in sectors relying heavily on SAP for enterprise resource planning (ERP), supply chain management, and customer relationship management. The vulnerability allows unauthenticated attackers to inject scripts that could lead to session hijacking, unauthorized data viewing, or manipulation within the affected application context. Although the impact on confidentiality and integrity is limited, such breaches can still result in exposure of sensitive business data, disruption of business processes, and potential compliance violations under regulations like GDPR. The availability of the service is not directly impacted, but the trustworthiness and security posture of the affected SAP applications could be undermined. Given SAP's critical role in many European industries including manufacturing, finance, and public sector, exploitation could facilitate further attacks or lateral movement within networks. The lack of known active exploitation reduces immediate risk but does not eliminate the threat, especially as attackers often develop exploits after public disclosure. Organizations with exposed SAP NetWeaver HTTP Provider Services should consider this vulnerability a medium risk that requires timely mitigation to prevent potential targeted attacks.

1. Apply official SAP patches or updates as soon as they become available for NetWeaver AS for Java 7.50 to address this vulnerability directly. 2. Implement strict input validation and output encoding on all HTTP headers processed by the SAP NetWeaver HTTP Provider Service to prevent script injection. 3. Employ web application firewalls (WAFs) with rules specifically designed to detect and block XSS payloads targeting SAP HTTP headers. 4. Restrict external access to SAP NetWeaver HTTP Provider Services by network segmentation and firewall rules to limit exposure to untrusted networks. 5. Monitor SAP application logs and HTTP traffic for unusual or suspicious header content indicative of attempted exploitation. 6. Educate SAP administrators and security teams about this vulnerability and encourage proactive security assessments of SAP environments. 7. Consider deploying Content Security Policy (CSP) headers and other browser-based mitigations to reduce the impact of potential XSS attacks. 8. Conduct regular security audits and penetration testing focused on SAP web interfaces to identify and remediate similar input validation issues.
