Campcodes Online Water Billing System SQL Injection Vulnerability

A SQL injection vulnerability has been identified in Campcodes Online Water Billing System version 1.0. The issue arises in the file '/Water_Billing_System/editecex.php', where the 'id' parameter is manipulated, allowing for the injection of malicious SQL queries. This vulnerability can be exploited remotely, without any authentication, leading to unauthorized database access, data modification or deletion, and potential exposure of sensitive information.

Impact

Exploitation of this vulnerability allows for SQL injection, enabling attackers to manipulate database queries. This could result in unauthorized data access, data leakage, data modification or deletion, and in some cases, could lead to remote code execution.

Reproduction
