A critical vulnerability has been discovered in the SourceCodester Employee Management System 1.. This vulnerability, known as the CVE-2024-1877, exposes the affected systems to potential SQL Injection attacks, allowing an attacker to manipulate and gain unauthorized access to sensitive data.
The vulnerability affects an unknown functionality of the file /cancel.php and is assigned the identifier VDB-254725. The attack can be executed remotely, and there is public disclosure of the exploit, which increases the urgency for organizations to mitigate the vulnerability.
Exploit Details
The core of the issue lies in the improper handling of user input in the 'id' argument of the file /cancel.php. Attackers can manipulate user input by injecting malicious SQL code containing "1%20or%201=1" as the 'id' argument value, leading to SQL Injection.
The following code snippet demonstrates how the vulnerability can be exploited
http://<example_url>/cancel.php?id=1%20or%201=1
By using this crafted URL, the attacker can potentially access all the records in the database without proper authorization, manipulate data, and possibly compromise the entire system.
