Summary

CVE-2025-31324 is a critical-severity Unrestricted Upload of File with Dangerous Type (CWE-434) vulnerability in Sap Netweaver. Its CVSS base score is 10.0 (Critical).

Operationally, exploitation aligns with the MITRE ATT&CK technique Exploit Public-Facing Application (T1190); ranked in the top 0.1% of CVEs by exploit likelihood; CISA has added it to the Known Exploited Vulnerabilities catalog.

The strongest mitigations our analysis identified map to SI-3 (Malicious Code Protection) and CM-7 (Least Functionality) — see the control section below for these in your framework.

Deeper analysis AI-assisted summary

Synthesised by an AI model from the NVD description and linked references — a reading aid, not an authoritative source.

SAP NetWeaver Visual Composer Metadata Uploader contains an authorization bypass vulnerability (CWE-434) that permits unauthenticated file uploads of arbitrary executable binaries. The flaw affects the SAP NetWeaver component and carries a CVSS 3.1 base score of 10.0, reflecting network-accessible attack vector, low complexity, no required privileges or user interaction, and complete loss of confidentiality, integrity, and availability with scope change to other system components.

Unauthenticated remote attackers can exploit the issue to upload and execute malicious binaries on the host, enabling full system compromise. Successful attacks can therefore result in arbitrary code execution with severe impact on the targeted SAP environment and any connected systems.

SAP has published remediation guidance in security note 3594142 and the April 2025 patch day release. Multiple independent reports confirm that the vulnerability was under active exploitation in the wild shortly after disclosure, including suspected zero-day usage prior to the availability of patches.

The associated EPSS score has risen sharply from a low baseline to a current value of 0.4366 with a recorded peak of 0.4871, indicating that exploitation interest increased materially after public disclosure.

Malicious-code protection at entry points blocks dangerous file types from being accepted and executed.

Least functionality restricts the file types and automatic processing capabilities the system will accept.

SC-18 Mobile Code partial match

Mobile-code controls define, authorize, and block unacceptable uploaded code before automatic processing occurs.

finds

Configuration and acceptance testing verify that file-upload handling enforces allowed types and does not permit dangerous content to be stored or executed.

prevents

Secure-coding guidelines and security testing explicitly address restrictions on allowed file types and upload handling, reducing the risk that dangerous file uploads are accepted without validation.

prevents

Mandated testing for malicious content and known vulnerabilities reduces the likelihood that an outsourced component will contain or accept dangerous file types that could later be uploaded or executed.

mitigates

Application allow-listing and pre-use scanning of received files directly blocks the introduction of executable content that has not been vetted, eliminating the primary vector for unrestricted dangerous file uploads.
