Overview
A high-severity SQL injection vulnerability, identified as CVE-2025-13420, has been discovered in itsourcecode Human Resource Management System (HRM) version 1.0. This vulnerability allows remote attackers to execute arbitrary SQL commands, potentially leading to sensitive data breaches, system compromise, and other malicious activities. Given its publicly available exploit and ease of exploitation, organizations using this software are strongly advised to take immediate action.
Technical Details
The vulnerability resides within the /src/store/EventStore.php file. Specifically, the application fails to properly sanitize the eventSubject argument, leading to SQL injection. An attacker can manipulate this parameter to inject malicious SQL code into database queries. The publicly available exploit demonstrates how this can be achieved remotely, highlighting the critical nature of this vulnerability.
CVSS Analysis
- CVE ID: CVE-2025-13420
- Severity: HIGH
- CVSS Score: 7.3
A CVSS score of 7.3 indicates a high-severity vulnerability. This score takes into account factors such as the ease of exploitation, the potential impact on confidentiality, integrity, and availability, and whether user interaction is required.
Possible Impact
Successful exploitation of this SQL injection vulnerability could have severe consequences, including:
- Data Breach: Unauthorized access to sensitive employee data, financial records, and other confidential information.
- System Compromise: Complete control over the database server, allowing attackers to modify or delete data.
- Application Downtime: Injection of malicious code that disrupts the functionality of the HRM system.
- Privilege Escalation: The possibility of gaining higher-level privileges within the system.
Mitigation or Patch Steps
To mitigate the risk posed by CVE-2025-13420, the following steps are recommended:
- Apply the Patch: Immediately apply the official patch provided by itsourcecode, if available. Check the itsourcecode.com website for updates and security advisories.
- Input Validation: Implement robust input validation and sanitization for all user-supplied data, especially the
eventSubjectparameter in/src/store/EventStore.php. - Prepared Statements: Utilize parameterized queries or prepared statements to prevent SQL injection attacks. This ensures that user input is treated as data, not as executable code.
- Web Application Firewall (WAF): Deploy a Web Application Firewall (WAF) to detect and block malicious requests targeting the vulnerable endpoint.
- Regular Security Audits: Conduct regular security audits and penetration testing to identify and address potential vulnerabilities in the HRM system.
