Description
Sparx Pro Cloud Server is vulnerable to Broken Access Control within communication with the database. Due to lack of permission checks, any low privileged user can run arbitrary SQL queries within database user context. The vendor was notified early about this vulnerability, but didn't respond with the details of vulnerability or vulnerable version range. Only version 6.1 (build 167) and below were tested and confirmed as vulnerable, other versions were not tested and might also be vulnerable.
