## How to fix


Use parameterized statements with typed identifiers instead of string concatenation, require administrator authentication for all mutation operations, and implement CSRF tokens to prevent unauthorized state-changing requests.

## Technical details

SQL injection occurs in admindocview.php, adminappview.php, approve.php, and disadd.php where the docid and appid parameters are concatenated directly into DELETE and UPDATE SQL statements without sanitization or parameterized queries. The affected scripts lack authentication checks, allowing unauthenticated remote attackers to execute arbitrary SQL commands; proof-of-concept demonstrates bulk deletion of all doctor records using a SQL OR condition.
