SQL Injection Vulnerability in SourceCoder Computer Repair Shop Management System v1.0 (manage_product.php)

Vulnerability Overview Vulnerability Name: SourceCoder Computer Repair Shop Management System in PHP/OOP Free Source Code v1.0 manage_product.php id SQL Injection #4 Vulnerability Type: SQL Injection Affected Product: Computer Repair Shop Management System in PHP/OOP Free Source Code Version: v1.0 Official Repository/Download Link: https://www.sourcecoder.com/sites/default/files/download/version23/crms_1.zip Vendor Homepage: https://www.sourcecoder.com/php/15286/computer-repair-shop-management-system-in-phpoop-free-source-code.html Submitter: gxqyy.org.cn Verification Status: Confirmed Verification Method: Validated in a local environment using the automated testing tool sqlmap. The vulnerable parameter was successfully identified, injectable payload types were confirmed, and usable proof-of-concept output was generated. Impact Scope Attack Conditions: No authentication or authorization required; accessible via the network under default installation. Potential Impact: In the local test environment, sqlmap successfully confirmed the SQL injection and produced direct evidence of exploitation, such as database identification, database enumeration, table enumeration, or sample data extraction. This demonstrates the possibility of unauthorized backend data disclosure and may allow data tampering or service impact, depending on the database privileges used by the application. Remediation 1. Use Prepared Statements and Parameter Binding: Ensure all SQL queries use prepared statements and parameter binding to avoid directly concatenating user input. 2. Implement Strict Input Validation and Sanitization: Perform strict validation and sanitization on all user inputs to ensure they conform to the expected format. 3. Apply the Principle of Least Privilege: Database accounts should follow the principle of least privilege, granting only the necessary permissions. 4. Conduct Regular Code Security Reviews and Security Testing: Perform regular code security reviews and security testing to promptly identify and fix potential security issues. POC Code Additional Information CVSS v3.1 Vector: - Attack Vector (AV): Network (N) - Attack Complexity (AC): Low (L) - Privileges Required (PR): None (N) - User Interaction (UI): None (N) - Scope (S): Unchanged (U) - Confidentiality (C): High (H) - Integrity (I): High (H) - Availability (A): High (H) Base Score: 9.8 The above is a summary of the key information regarding this vulnerability.
