Overview
CVE-2025-13303 is a medium-severity SQL injection vulnerability affecting Courier Management System version 1.0. This vulnerability allows a remote attacker to inject malicious SQL code through the “Consignment” argument in the /search-edit.php file. Successful exploitation of this vulnerability could allow an attacker to read, modify, or delete sensitive data within the application’s database.
This vulnerability has been publicly disclosed, and proof-of-concept (PoC) exploits are available, increasing the risk of exploitation.
Technical Details
The vulnerability resides within the /search-edit.php file of the Courier Management System 1.0. The application fails to properly sanitize user-supplied input passed through the “Consignment” parameter before using it in an SQL query. This allows an attacker to inject arbitrary SQL code, potentially bypassing authentication and authorization controls.
Specifically, the unsanitized Consignment parameter is directly concatenated into an SQL query. For example:
// Vulnerable code (example)
$consignment_id = $_GET['Consignment'];
$query = "SELECT * FROM shipments WHERE consignment_id = '" . $consignment_id . "'";
// Execute the query
An attacker could provide a malicious payload such as ' OR '1'='1 as the Consignment value to bypass the intended query logic.
CVSS Analysis
- CVE ID: CVE-2025-13303
- Severity: MEDIUM
- CVSS Score: 6.3
This CVSS score reflects the remote exploitability of the vulnerability, its potential impact on data confidentiality and integrity, and the fact that no user interaction is required for exploitation.
Possible Impact
Successful exploitation of CVE-2025-13303 can lead to several critical security consequences:
- Data Breach: Attackers can extract sensitive information such as customer data, shipment details, and internal system configurations.
- Data Manipulation: Malicious actors can modify or delete data, potentially disrupting operations and causing financial losses.
- Account Takeover: By manipulating user data, attackers could gain unauthorized access to administrator accounts and further compromise the system.
- Denial of Service (DoS): In some cases, attackers can use SQL injection to cause the database server to crash, leading to a denial of service.
Mitigation and Patch Steps
To address CVE-2025-13303, the following mitigation steps are recommended:
- Apply the Patch (if available): Check the vendor’s website (code-projects.org) for a security patch or updated version of Courier Management System. Upgrade to the latest version as soon as possible.
- Input Validation: Implement robust input validation and sanitization on all user-supplied data, especially the “Consignment” parameter. Use parameterized queries or prepared statements to prevent SQL injection.
- Web Application Firewall (WAF): Deploy a Web Application Firewall (WAF) to detect and block malicious SQL injection attempts. Configure the WAF to filter out suspicious patterns and payloads.
- Least Privilege Principle: Ensure that the database user account used by the application has only the necessary privileges to perform its functions. Avoid granting excessive permissions.
- Regular Security Audits: Conduct regular security audits and penetration testing to identify and address potential vulnerabilities in the application.
