An SQL injection vulnerability in the pjActionGetUser function of PHPJabbers Cinema Booking System v2.0 allows attackers to manipulate database queries via the column parameter. Exploiting this flaw can lead to unauthorized information disclosure, privilege escalation, or database manipulation.
The product constructs all or part of an SQL command using externally-influenced input from an upstream component, but it does not neutralize or incorrectly neutralizes special elements that could modify the intended SQL command when it is sent to a downstream component. Without sufficient removal or quoting of SQL syntax in user-controllable inputs, the generated SQL query can cause those inputs to be interpreted as SQL instead of ordinary user data.
