Overview
A high-severity SQL injection vulnerability, identified as CVE-2025-13235, has been discovered in itsourcecode Inventory Management System version 1.0. This vulnerability affects the /admin/login.php file and allows remote attackers to execute arbitrary SQL commands by manipulating the user_email parameter. The exploit has been publicly disclosed, making immediate mitigation crucial.
Technical Details
The vulnerability resides within the login functionality of the application. Specifically, the /admin/login.php script fails to properly sanitize user-supplied input for the user_email parameter. An attacker can craft a malicious SQL query embedded within the user_email field, which is then directly executed against the database. This allows the attacker to bypass authentication, extract sensitive data, modify database records, or even potentially gain full control of the underlying database server.
Successful exploitation does not require any special privileges or authentication prior to the attack. This makes it easily exploitable by anyone with network access to the application.
CVSS Analysis
This vulnerability has been assigned a CVSS score of 7.3, classifying it as HIGH severity.
- CVSS Score: 7.3
- Attack Vector: Network (AV:N)
- Attack Complexity: Low (AC:L)
- Privileges Required: None (PR:N)
- User Interaction: None (UI:N)
- Scope: Unchanged (S:U)
- Confidentiality Impact: High (C:H)
- Integrity Impact: High (I:H)
- Availability Impact: High (A:H)
The high CVSS score reflects the ease of exploitation and the significant potential impact on confidentiality, integrity, and availability of the system.
Possible Impact
Exploitation of this SQL injection vulnerability could lead to a variety of severe consequences, including:
- Data Breach: Unauthorized access to sensitive data such as user credentials, customer information, and financial records.
- Account Takeover: Attackers can bypass authentication and gain control of administrator accounts.
- Data Manipulation: Modification or deletion of critical data within the inventory management system.
- System Compromise: Potential for complete system compromise, allowing attackers to install malware or use the system as a launchpad for further attacks.
- Denial of Service (DoS): Disrupting the normal operation of the inventory management system.
Mitigation and Patch Steps
Given the severity of this vulnerability and the availability of a public exploit, immediate action is required to mitigate the risk. The following steps are recommended:
- Apply the Patch: Check the itsourcecode website for a patch or updated version of the Inventory Management System. Install the patch as soon as possible. (As of this writing there doesn’t seem to be one). Contact itsourcecode directly.
- Input Validation: Implement robust input validation and sanitization for all user-supplied data, particularly the
user_emailparameter in/admin/login.php. 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 with rules specific to this vulnerability.
- Least Privilege: Ensure that the database user account used by the application has only the necessary privileges required for its operation. Avoid granting excessive permissions.
- Regular Security Audits: Conduct regular security audits and penetration testing to identify and address potential vulnerabilities in your applications.
- Temporary Workaround (If Patch Unavailable): If a patch is not immediately available, consider implementing a temporary workaround by using a WAF rule to block common SQL injection patterns in the
user_emailparameter. This should only be considered a temporary measure until a proper patch is released.
