We started looking around the client’s TeamCity instance to see how we could increase the impact of the issue. Find vulnerabilities and remediate associated risk while. This was already a success, but we wanted to show more impact on XSS. FlexNet Code Insight is a single integrated solution for open source license compliance and security. The CI server suffered from a security misconfiguration, and we were able to gain access. On a recent client engagement, we were challenged to gain access to their private CI server.
