ProjeQtor < 12.4.4 Unauthenticated SQL Injection via Login

ProjeQtor versions 7.0 through 12.4.3 contain an unauthenticated SQL injection vulnerability in the login functionality where the login variable is directly concatenated into a SQL query without parameterization or sanitization. Attackers can inject arbitrary SQL expressions through the username field at the authentication endpoint to create privileged accounts, read sensitive data, and execute operating system commands if the database user has elevated permissions.
