Overview
CVE-2025-13579 describes a medium-severity SQL injection vulnerability discovered in Code-Projects Library System version 1.0. This vulnerability allows a remote attacker to execute arbitrary SQL commands by manipulating the ID argument in the /return.php file. The exploit is publicly available, making immediate action crucial for affected systems.
Technical Details
The vulnerability resides in the /return.php file of the Code-Projects Library System 1.0. The application fails to properly sanitize the ID parameter before using it in a SQL query. An attacker can inject malicious SQL code into this parameter, potentially allowing them to:
- Read sensitive data from the database, including user credentials, book information, and transaction details.
- Modify data in the database, leading to data corruption or unauthorized actions.
- Potentially gain complete control of the database server, depending on database privileges.
The attack is considered remote as it can be performed over the network without requiring local access to the server.
CVSS Analysis
The Common Vulnerability Scoring System (CVSS) assigns CVE-2025-13579 a score of 6.3, classifying it as a MEDIUM severity vulnerability. The CVSS vector is likely AV:N/AC:L/PR:N/UI:N/S:U/C:L/I:L/A:N. This translates to:
- Attack Vector (AV): Network (N) – The vulnerability can be exploited remotely over the network.
- Attack Complexity (AC): Low (L) – The attack requires little to no specialized knowledge or conditions.
- Privileges Required (PR): None (N) – No authentication is required to exploit the vulnerability.
- User Interaction (UI): None (N) – No user interaction is required to trigger the vulnerability.
- Scope (S): Unchanged (U) – The vulnerability only affects the vulnerable component.
- Confidentiality Impact (C): Low (L) – Limited access to confidential information.
- Integrity Impact (I): Low (L) – Limited modification of data.
- Availability Impact (A): None (N) – No impact on system availability.
Possible Impact
Successful exploitation of this vulnerability could lead to several negative consequences:
- Data Breach: Sensitive user data, including passwords and personal information, could be exposed.
- Data Manipulation: Attackers could alter library records, change loan statuses, or manipulate financial transactions.
- System Compromise: In the worst-case scenario, an attacker could gain control of the database server, potentially leading to a complete system compromise.
- Reputational Damage: A successful attack can damage the reputation of the library or organization using the vulnerable system.
Mitigation and Patch Steps
To mitigate the risk posed by CVE-2025-13579, the following steps are recommended:
- Apply the Patch: The most effective solution is to apply the official patch released by Code-Projects (if available). Check the Code-Projects website for updates.
- Input Validation: Implement robust input validation on the
IDparameter in the/return.phpfile. Ensure that the input is properly sanitized and escaped before being used in SQL queries. 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 requests targeting the vulnerability.
- Database Permissions: Review and restrict database user privileges to the minimum required for the application to function correctly. Avoid using overly permissive accounts.
- Regular Security Audits: Conduct regular security audits and penetration testing to identify and address vulnerabilities in your systems.
