Technical details
A privilege escalation vulnerability exists in Balbooa Gridbox versions prior to 2.20.2. The registration method fails to properly validate or restrict the usergroup IDs provided in registration requests. An unauthenticated remote attacker can exploit this by submitting a crafted registration request that includes an administrative usergroup ID, resulting in the creation of a new account with full administrative permissions. This is a failure of improper access control (CWE-284). The issue is resolved in version 2.20.2.
