GSoC 2021: Patch Security Vulnerabilities Identified by NCSU

Abstract

Late last year, OpenMRS began collaborating with researchers from North Carolina State University (NCSU) to better secure the OpenMRS Reference Application. NCSU researchers, using cutting-edge security assessment techniques, have identified almost 300 distinct security issues. Many of those issues are relatively low-complexity, requiring one-line patches. This is a great opportunity for students who are interested in software security to get first-hand experience in the field.
