Contributed to the projectdiscovery/nuclei-templates repository by developing a YAML-based Proof of Concept to detect a high-severity arbitrary file read vulnerability in Yonyou NC. Focused on exploit development and vulnerability research, the work involved crafting explicit HTTP request patterns and matching conditions to ensure reliable detection with minimal false positives. This addition expanded automated security scanning coverage for enterprise ERP deployments, supporting improved threat modeling and remediation processes. Maintained clear, descriptive commit messages to facilitate collaboration and auditing. Leveraged skills in penetration testing and YAML to deliver a targeted security enhancement, addressing a critical gap in existing vulnerability detection workflows.
