CVE-2025-7199 is a critical SQL Injection vulnerability identified in version 1.0 of the code-projects Library System, specifically affecting the /notapprove.php file. The vulnerability arises from improper sanitization or validation of the 'ID' parameter, which can be manipulated by an attacker to inject malicious SQL queries. This flaw allows remote attackers to execute arbitrary SQL commands on the backend database without requiring authentication or user interaction. The vulnerability is remotely exploitable over the network (AV:N), with low attack complexity (AC:L), no privileges required (PR:N), and no user interaction needed (UI:N). The impact on confidentiality, integrity, and availability is limited (VC:L, VI:L, VA:L), suggesting partial but significant compromise potential. The CVSS v4.0 base score is 6.9, categorized as medium severity, reflecting the balance between ease of exploitation and the limited scope of impact. Although no known exploits are currently reported in the wild, the public disclosure of the vulnerability increases the risk of exploitation. The absence of patches or mitigation links indicates that organizations using this software version remain vulnerable. SQL Injection vulnerabilities can lead to unauthorized data access, data modification, or even full system compromise depending on the database privileges and application context. The vulnerability's presence in a library management system suggests potential exposure of sensitive user data, borrowing records, or administrative controls, which could be leveraged for further attacks or data breaches.

For European organizations utilizing the code-projects Library System 1.0, this vulnerability poses a significant risk to the confidentiality and integrity of their data. Libraries often store personal information about patrons, including identification details, contact information, and borrowing history. Exploitation could lead to unauthorized disclosure of this sensitive data, violating GDPR and other privacy regulations, resulting in legal and reputational consequences. Additionally, attackers might manipulate or delete records, disrupting library operations and availability of services. Given the remote and unauthenticated nature of the exploit, attackers can target these systems from anywhere, increasing the threat landscape. The lack of known exploits in the wild currently reduces immediate risk but does not eliminate it, especially as public disclosure may prompt attackers to develop exploits. European organizations relying on this software without timely patching or mitigation could face data breaches, service disruptions, and compliance violations.

Organizations should immediately assess their deployment of code-projects Library System 1.0 and prioritize upgrading to a patched version once available. In the absence of an official patch, implement the following mitigations: 1) Employ Web Application Firewalls (WAFs) with rules specifically designed to detect and block SQL injection attempts targeting the 'ID' parameter in /notapprove.php. 2) Conduct thorough input validation and sanitization on all parameters, especially 'ID', using parameterized queries or prepared statements to prevent injection. 3) Restrict database user privileges to the minimum necessary, avoiding use of high-privilege accounts by the application. 4) Monitor logs for suspicious activities related to SQL errors or unusual queries on the affected endpoint. 5) Isolate the affected system within the network to limit exposure and apply network segmentation. 6) Educate development and security teams about secure coding practices to prevent similar vulnerabilities. 7) Prepare incident response plans to quickly address any exploitation attempts. These targeted actions go beyond generic advice by focusing on immediate protective controls and long-term secure development practices.
