Overview
A high-severity SQL injection vulnerability, identified as CVE-2025-13485, has been discovered in itsourcecode Online File Management System version 1.0. This flaw allows remote attackers to potentially execute arbitrary SQL commands, leading to unauthorized data access, modification, or even complete system compromise. The exploit is publicly available, making it crucial to address this vulnerability immediately.
Technical Details
The vulnerability resides in the /ajax.php?action=login endpoint. Specifically, the Username argument is susceptible to SQL injection. By manipulating this argument, an attacker can inject malicious SQL code that is then executed by the application’s database. This bypasses normal authentication mechanisms and grants unauthorized access. The vulnerable code doesn’t properly sanitize or validate the input before using it in SQL queries.
Affected Component: /ajax.php?action=login
Affected Parameter: Username
CVSS Analysis
- CVSS Score: 7.3 (HIGH)
- Vector: (This would typically include the CVSS vector string, but as a demonstration, we’ll explain the high score elements)
The high CVSS score reflects the following:
- Attack Vector: Network (AV:N) – The vulnerability is exploitable remotely.
- Attack Complexity: Low (AC:L) – Exploitation requires minimal effort.
- Privileges Required: None (PR:N) – No prior privileges are required to exploit the vulnerability.
- User Interaction: None (UI:N) – No user interaction is required to trigger the vulnerability.
- Scope: Changed (S:C) – An attacker can impact components beyond the vulnerable component itself.
- Confidentiality Impact: High (C:H) – An attacker can gain access to sensitive information.
- Integrity Impact: High (I:H) – An attacker can modify sensitive data.
- Availability Impact: High (A:H) – An attacker can cause a denial-of-service condition.
Possible Impact
Successful exploitation of this SQL injection vulnerability can have severe consequences, including:
- Data Breach: Exposure of sensitive user data, application configurations, and other critical information.
- Account Takeover: Gaining unauthorized access to user accounts, potentially leading to further malicious activities.
- System Compromise: Complete control over the underlying server, allowing attackers to install malware, modify system files, or launch attacks against other systems.
- Denial of Service: Disrupting the availability of the application, preventing legitimate users from accessing it.
Mitigation or Patch Steps
Currently, there is no official patch available from itsourcecode. Until a patch is released, the following mitigation steps are recommended:
- Input Validation: Implement strict input validation and sanitization for all user-supplied data, especially the
Usernameparameter in the/ajax.php?action=loginendpoint. 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 specifically designed to protect against SQL injection attacks.
- Database Permissions: Apply the principle of least privilege to database user accounts. Grant only the necessary permissions required for the application to function correctly.
- Code Review: Conduct thorough code reviews to identify and address potential vulnerabilities in the application code.
- Disable the affected endpoint: If feasible, temporarily disable the `/ajax.php?action=login` endpoint until a proper fix can be implemented.
- Monitor logs: Continuously monitor application logs for suspicious activity and potential SQL injection attempts.
Note: It is highly recommended to contact itsourcecode directly to inquire about a patch release timeline. Regularly check their website for updates.
