CVE-2019-0267 in Manufacturing Integration
Summary
by MITRE
SAP Manufacturing Integration and Intelligence, versions 15.0, 15.1 and 15.2, (Illuminator Servlet) currently does not provide Anti-XSRF tokens. This might lead to XSRF attacks in case the data is being posted to the Servlet from an external application.

SAP Manufacturing Integration and Intelligence version 15.0, 15.1 and 15.2 contains a critical security vulnerability in its Illuminator Servlet component that lacks proper Cross-Site Request Forgery (CSRF) protection mechanisms. This vulnerability falls under the CWE-352 category, which specifically addresses Cross-Site Request Forgery attacks where malicious actors can trick authenticated users into executing unintended commands against a web application they are currently authenticated to. The absence of Anti-XSRF tokens in the servlet implementation creates a significant attack surface that adversaries can exploit to perform unauthorized actions on behalf of legitimate users.
The technical flaw manifests in the Illuminator Servlet's failure to implement proper anti-cross-site request forgery controls during data submission processes. When external applications post data to this servlet, there is no mechanism to verify that the request originates from a legitimate source within the same session context. This vulnerability enables attackers to craft malicious web pages or applications that can trigger unauthorized operations on the affected SAP system without requiring user credentials. The attack typically involves tricking a victim user's browser into submitting requests to the vulnerable servlet, leveraging the user's existing authentication session to perform actions that the user did not intend to authorize.
The operational impact of this vulnerability extends beyond simple data manipulation risks as it can potentially lead to complete system compromise and unauthorized access to sensitive manufacturing intelligence data. Attackers could exploit this weakness to modify production parameters, alter manufacturing processes, or access confidential operational information that could disrupt production workflows or compromise intellectual property. The vulnerability particularly affects organizations relying on SAP Manufacturing Integration and Intelligence for critical manufacturing operations, where unauthorized changes to production data could result in significant financial losses, safety hazards, or regulatory compliance violations. Additionally, the attack vector is particularly dangerous because it can be executed through social engineering techniques, making it difficult to detect and prevent.
Organizations should implement immediate mitigations including updating to patched versions of SAP Manufacturing Integration and Intelligence, implementing additional security controls such as custom anti-CSRF tokens, and conducting thorough security assessments of all servlet components. The vulnerability aligns with ATT&CK technique T1566 which covers phishing attacks that can be used to deliver malicious payloads designed to exploit such CSRF vulnerabilities. Security teams should also consider implementing web application firewalls, monitoring for suspicious request patterns, and establishing proper input validation controls to prevent exploitation. The recommended remediation approach includes not only patching the specific vulnerability but also conducting comprehensive security reviews of all web application components to identify similar weaknesses in the broader system architecture. Organizations should also implement proper security awareness training to help users recognize potential phishing attempts that could leverage this vulnerability.
