# Vulnerability and Indicator of Compromise (IoC) Scanner for CVE-2025-31324 (Visual Composer Metadata Uploader Vulnerability)

[CVE-2025-31324](https://www.google.com/url?q=https://nvd.nist.gov/vuln/detail/CVE-2025-31324&sa=D&source=editors&ust=1745779568690662&usg=AOvVaw1IqVqaCZ9oGfB2iCSZIYC4) is a critical (CVSSv3 10) vulnerability affecting SAP NetWeaver systems, specifically within the Visual Composer Metadata Uploader component. This vulnerability allows unauthenticated attackers to upload arbitrary files to the system, leading to potential remote code execution and complete system compromise.

Recognizing the critical nature of this vulnerability, and observing evidence of active exploitation both by Onapsis Threat Intelligence and reported by multiple IR firms and security researchers, Onapsis developed and is releasing this open-source tool to assist SAP customers. Our goal is to empower information security and SAP administration teams to rapidly assess exposure and evaluate whether their systems could have been targeted or compromised. The Visual Composer/Metadata Uploader component is often present in SAP Java NetWeaver, increasing the risk of unmonitored attack surfaces in enterprise environments.

We will continue to enhance this tool as additional threat intelligence and forensic insights are gathered by our products, research team, and the broader cybersecurity community.
