CVE-2026-24316 in NetWeaver Application Server for ABAP
Summary
by MITRE • 03/10/2026
SAP NetWeaver Application Server for ABAP provides an ABAP Report for testing purposes, which allows to send HTTP requests to arbitrary internal or external endpoints. The report is therefore vulnerable to Server-Side Request Forgery (SSRF). Successful exploitation could lead to interaction with potentially sensitive internal endpoints, resulting in a low impact on data confidentiality and integrity. There is no impact on availability of the application.

SAP NetWeaver Application Server for ABAP contains a vulnerable ABAP report designed for testing purposes that enables the execution of HTTP requests to any internal or external endpoints. This functionality, while intended for legitimate testing scenarios, creates a significant security vulnerability by allowing unauthorized access to internal network resources through server-side request forgery attacks. The report's design permits arbitrary endpoint targeting without proper input validation or access controls, making it a potential vector for attackers to explore internal network topology and access restricted systems. The vulnerability resides in the report's lack of proper endpoint validation mechanisms, which allows attackers to specify any URL or IP address for HTTP request execution. This flaw directly aligns with CWE-918, which describes server-side request forgery vulnerabilities where applications fetch resources from untrusted sources without proper validation. The security implications extend beyond simple information disclosure, as successful exploitation could enable attackers to probe internal systems, potentially identifying sensitive services running on internal networks that would otherwise remain hidden from external reconnaissance. The vulnerability's impact is classified as low for data confidentiality and integrity, suggesting that while internal endpoints may be accessible, the potential for data exfiltration or modification remains limited. However, the ability to interact with internal endpoints creates opportunities for further reconnaissance and potentially more serious attacks. The report's functionality, though designed for testing, lacks proper sandboxing or access controls that would normally prevent such unrestricted access to internal network resources. Attackers could leverage this vulnerability to map internal network structures, identify running services, and potentially discover additional vulnerabilities within the internal infrastructure. The absence of impact on application availability indicates that while the vulnerability can be exploited to access internal resources, it does not directly enable denial-of-service attacks or system disruption. This type of vulnerability often falls under the ATT&CK technique T1566, which involves phishing with a malicious attachment or link, but in this case represents an internal attack vector where the vulnerability allows lateral movement within the network. The lack of proper input validation and endpoint restrictions in the test report creates an unintended attack surface that could be exploited by both internal and external adversaries. Organizations utilizing SAP NetWeaver Application Server for ABAP should consider implementing access controls to restrict who can execute the vulnerable report, while also ensuring that the report is not available in production environments. The vulnerability demonstrates the importance of proper input validation and the principle of least privilege, where even testing functionality should not provide unrestricted access to internal network resources. Security measures should include network segmentation, firewall rules to restrict internal endpoint access, and regular audits to ensure that test functionality is properly isolated from production systems. The vulnerability also highlights the need for proper security testing procedures that do not introduce exploitable functionality into production environments, as the report's intended testing purpose should not compromise overall system security. Organizations should implement proper access controls and monitoring to detect unauthorized use of potentially vulnerable test functionality, ensuring that such reports are only accessible to authorized personnel with legitimate testing requirements.
