CRITICAL 10.0

DescriptionCVE.org

The Invoker Servlet on SAP NetWeaver Application Server Java platforms, possibly before 7.3, does not require authentication, which allows remote attackers to execute arbitrary code via an HTTP or HTTPS request, as exploited in the wild in 2013 through 2016, aka a "Detour" attack.

AnalysisAI

Remote unauthenticated code execution in SAP NetWeaver Application Server Java (pre-7.3) through the Invoker Servlet allows attackers to bypass authentication and execute arbitrary code. Confirmed actively exploited (CISA KEV) from 2013 through 2016 in 'Detour' attacks targeting SAP business applications. CVSS 10.0 with EPSS 16.90% (95th percentile) indicates both maximum theoretical severity and sustained real-world exploitation. This remains a critical priority for organizations running legacy SAP NetWeaver Java instances despite the vulnerability's age.

Technical ContextAI

The Invoker Servlet is a built-in component of SAP NetWeaver Application Server Java that provides dynamic servlet invocation capabilities. The vulnerability stems from CWE-306 (Missing Authentication for Critical Function), where the Invoker Servlet endpoint accepts HTTP/HTTPS requests without requiring authentication credentials. SAP NetWeaver Application Server Java is the runtime platform for SAP's enterprise applications including ERP, CRM, and SCM solutions. The affected component allows arbitrary servlet class invocation through specially crafted URLs, effectively creating an authentication bypass path into the Java application server. This architectural flaw exists in versions prior to 7.3, though the exact version range affected is documented in SAP Note 1445998.

RemediationAI

Apply SAP Security Note 1445998 immediately, which provides patches and configuration guidance to disable or properly secure the Invoker Servlet component. Upgrade SAP NetWeaver Application Server Java to version 7.3 or later where the vulnerability is resolved. If immediate patching is impossible, implement emergency compensating controls: disable the Invoker Servlet entirely through Java EE configuration if not required for business operations (note: this may break applications relying on dynamic servlet invocation); restrict network access to NetWeaver Java HTTP/HTTPS ports (typically 50000, 50001) to authorized management networks only using firewall rules or network segmentation (trade-off: impacts legitimate remote access); deploy web application firewall (WAF) rules to block HTTP requests matching Invoker Servlet URL patterns (trade-off: requires pattern maintenance and may be bypassed). Consult Onapsis research documentation at http://www.onapsis.com/research/publications/sap-security-in-depth-vol4-the-invoker-servlet-a-dangerous-detour-into-sap-java-solutions and US-CERT Alert TA16-132A at http://www.us-cert.gov/ncas/alerts/TA16-132A for additional hardening guidance. Prioritize systems processing sensitive business data or connected to financial/HR systems.
