SQL Injection vulnerability in Online-Bookstore-Project-In-PHP v1.0 allows a local attacker to execute arbitrary code via the admin_delete.php component.
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.
