A Python3 script designed to identify potential dependency confusion vulnerabilities in Nexus Repository Manager environments. The tool scans repositories to detect artifacts with identical names across different repositories, which could indicate susceptibility to dependency confusion attacks. These attacks occur when malicious packages with the same names as internal packages are uploaded to public repositories, potentially causing systems to download and execute malicious code instead of legitimate internal dependencies. The checker is compatible with both NXRM3 OSS and PRO versions. It analyzes repository contents and generates reports highlighting naming conflicts that could be exploited by attackers attempting to inject malicious dependencies into software supply chains. The tool is specifically designed for NXRM3 environments and is not recommended for use with NXRM2 systems that utilize slow storage solutions like NFS due to performance considerations.
