Working on a penetration test for a large insurance company in cooperation with OPTIMAbit I discovered several critical security issues in a professional WIKI product called Confluence that is sold by Atlassian to corporate customers.
The vendor offers an open ticket system to directly report security issues to development. Vendor response was very quick and a new release of the product fixing all reported vulnerabilities was issued within 1 month of reporting.
The reported vulnerabilities included several Cross Site Scripting and one critical privilege escalation issue. For further information please refer to Atlassian's security advisory.
I also want to thank Atlassian for giving proper credits for helping them solve these issues.
