Sourcecodester Personnel Property Equipment System SQL Injection Vulnerability

A SQL injection vulnerability has been identified in Sourcecodester Personnel Property Equipment System version 1.0. The issue resides in the 'advance_search.php' file within the admin directory. The vulnerability allows attackers to manipulate SQL queries, potentially leading to unauthorized data access or modification.

Impact

Exploitation of this vulnerability allows for SQL injection, where an attacker can interfere with the application's database queries. This could lead to unauthorized data access, data manipulation, or in some cases, executing administrative operations on the database.

Reproduction

To reproduce this vulnerability, send a POST request to '/ppes/admin/advance_search.php' with the 'item_name' parameter set to a value such as 'linovo' and the 'item_serial' parameter injected with a SQL payload, such as '1' and updatexml(1,concat(0x7e,database()),3). This injection exploits the application's SQL query handling, allowing the attacker to extract database information.
