SQL Injection vulnerability in index.php in phpgurukul Teacher Subject Allocation Management System 1.0 allows attackers to run arbitrary SQL commands and obtain sensitive information via the 'searchdata' parameter.
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.
