Overview
A high-severity SQL injection vulnerability, identified as CVE-2025-13299, has been discovered in itsourcecode Web-Based Internet Laboratory Management System version 1.0. This flaw allows remote attackers to inject arbitrary SQL commands, potentially leading to unauthorized data access, modification, or deletion. The vulnerability has been publicly disclosed and a proof-of-concept exploit is available, making it crucial for administrators to take immediate action.
Technical Details
The vulnerability resides within the /user/controller.php file of the application. By manipulating specific input parameters, an attacker can inject malicious SQL code that is then executed by the database server. This allows the attacker to bypass authentication mechanisms, extract sensitive information, or even gain complete control over the underlying database.
The specific vulnerable function within /user/controller.php is currently undisclosed in full detail, emphasizing the need for thorough code review and testing. Publicly available exploits targeting this vulnerability highlight the potential for widespread exploitation.
CVSS Analysis
This vulnerability has been assigned a CVSS score of 7.3, indicating a high severity. The breakdown typically includes:
- Attack Vector: Network (AV:N)
- Attack Complexity: Low (AC:L)
- Privileges Required: None (PR:N)
- User Interaction: None (UI:N)
- Scope: Changed (S:C)
- Confidentiality Impact: High (C:H)
- Integrity Impact: High (I:H)
- Availability Impact: High (A:H)
This high score reflects the ease of exploitation and the significant potential impact of a successful attack.
Possible Impact
A successful exploitation of CVE-2025-13299 could lead to severe consequences, including:
- Data Breach: Exposure of sensitive student, faculty, and laboratory data.
- Account Compromise: Unauthorized access to user accounts, including administrative privileges.
- System Takeover: Potential for complete compromise of the server hosting the application.
- Data Manipulation: Modification or deletion of critical data, leading to operational disruption.
- Denial of Service: Attackers could potentially disrupt access to the lab management system for legitimate users.
Mitigation and Patch Steps
To mitigate the risk associated with CVE-2025-13299, the following steps are recommended:
- Apply the Patch (If Available): Check the itsourcecode website and support channels for a security patch or update that addresses this vulnerability. This is the most effective solution.
- Input Sanitization: Implement rigorous input validation and sanitization on all user-supplied data to prevent SQL injection attacks. This should be applied to all input points, especially those used in database queries.
- Parameterized Queries: Use parameterized queries or prepared statements instead of directly embedding user input into SQL queries. This prevents the database from interpreting user input as SQL code.
- 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 SQL injection attacks.
- Principle of Least Privilege: Ensure that the database user account used by the application has only the necessary privileges. Avoid granting excessive permissions that could be exploited in case of a successful injection.
- Regular Security Audits: Conduct regular security audits and penetration testing to identify and address potential vulnerabilities in the application and its infrastructure.
