The vulnerability resides within the \u003ccode\u003e/purchase.php\u003c/code\u003e file, specifically in the handling of the \u003ccode\u003ecustom\u003c/code\u003e argument. This allows a remote attacker to inject arbitrary SQL commands into the application's database queries. This is made possible by insufficient sanitization of user-supplied input. The exploit has been publicly disclosed, increasing the risk of exploitation. Successful exploitation could lead to unauthorized data access, modification, or deletion.\u003c/p\u003e\n\u003ch2 id=\"attack-chain\"\u003eAttack Chain\u003c/h2\u003e\n\u003col\u003e\n\u003cli\u003eThe attacker identifies a vulnerable instance of SourceCodester Food Ordering System 1.0 exposed to the internet.\u003c/li\u003e\n\u003cli\u003eThe attacker crafts a malicious HTTP request targeting the \u003ccode\u003e/purchase.php\u003c/code\u003e endpoint.\u003c/li\u003e\n\u003cli\u003eThe attacker injects SQL code into the \u003ccode\u003ecustom\u003c/code\u003e parameter of the HTTP request.\u003c/li\u003e\n\u003cli\u003eThe web server receives the crafted HTTP request and passes the \u003ccode\u003ecustom\u003c/code\u003e parameter value to the application's SQL query.\u003c/li\u003e\n\u003cli\u003eDue to the lack of proper sanitization, the injected SQL code is executed by the database server.\u003c/li\u003e\n\u003cli\u003eThe attacker is able to read sensitive information such as user credentials or order details from the database.\u003c/li\u003e\n\u003cli\u003eThe attacker may further modify or delete data within the database.\u003c/li\u003e\n\u003cli\u003eThe attacker can potentially gain complete control of the database server and, potentially, the entire system, depending on database permissions.\u003c/li\u003e\n\u003c/ol\u003e\n\u003ch2 id=\"impact\"\u003eImpact\u003c/h2\u003e\n\u003cp\u003eSuccessful exploitation of CVE-2026-4839 can lead to a range of damaging consequences. Attackers could gain unauthorized access to sensitive customer data, including personal information, order history, and payment details. This data could be used for identity theft, financial fraud, or sold on the dark web. The vulnerability could also be exploited to modify or delete data, disrupting the application's functionality and potentially causing financial losses.
