Time-efficient assessment of open-source projects for Red Teamers

It is more and more common to face opensource projects during Red Team engagements. Due to time and efficiency constraints related to such assessments, it is always enjoyable to discover “quick-win” 0day vulnerabilities that will allow progressing in the intrusion and pivoting to critical networks or services. In this talk, we try to describe a methodology that allowed us to quickly discover numerous critical vulnerabilities in a widely-adopted project, GLPI. We will also discuss these findings and the security mechanisms that were implemented and how they were defeated.
