The vulnerability resides within the application's backend logic, specifically in the '/classes/Master.php' file when handling the 'delete_product' action. An attacker can manipulate the 'id' parameter to perform a SQL injection attack. Because this endpoint does not properly neutralize special elements used in SQL commands, a remote, unauthenticated attacker can inject arbitrary SQL queries. This allows for unauthorized interaction with the underlying database, which may lead to data exfiltration, modification, or potential loss of system integrity. Publicly available exploit code has been disclosed, increasing the risk of exploitation by malicious actors. Organizations running this software on internet-facing systems should treat this as a high-priority remediation item.\u003c/p\u003e\n\u003ch2 id=\"attack-chain\"\u003eAttack Chain\u003c/h2\u003e\n\u003col\u003e\n\u003cli\u003eAttacker performs reconnaissance to identify instances of the vulnerable SourceCodester Computer Repair Shop Management System.\u003c/li\u003e\n\u003cli\u003eAttacker crafts a malicious HTTP GET or POST request targeting the '/classes/Master.php' endpoint.\u003c/li\u003e\n\u003cli\u003eAttacker specifies the 'f' parameter as 'delete_product' to trigger the vulnerable code path.\u003c/li\u003e\n\u003cli\u003eAttacker injects a malicious SQL payload into the 'id' parameter of the request.\u003c/li\u003e\n\u003cli\u003eThe application fails to sanitize the input and passes the tainted 'id' string directly into a database query.\u003c/li\u003e\n\u003cli\u003eThe database executes the injected SQL command, allowing the attacker to bypass access controls or extract sensitive data.\u003c/li\u003e\n\u003cli\u003eAttacker retrieves the output of the query, potentially leading to total system compromise or data exfiltration.\u003c/li\u003e\n\u003c/ol\u003e\n\u003ch2 id=\"impact\"\u003eImpact\u003c/h2\u003e\n\u003cp\u003eSuccessful exploitation of this vulnerability permits an unauthenticated remote attacker to gain unauthorized access to the application's database. This can lead to the exposure of sensitive shop records, customer information, or administrative credentials. In a computer repair environment, this could involve the theft of personally identifiable information (PII) or business-critical configuration data.
