CVE-2025-6902 is a critical SQL Injection vulnerability identified in version 1.0 of the code-projects Inventory Management System, specifically within the /php_action/editUser.php file. The vulnerability arises from improper sanitization or validation of the 'edituserName' parameter, which allows an attacker to inject malicious SQL code remotely without requiring authentication or user interaction. This injection flaw can enable attackers to manipulate backend database queries, potentially leading to unauthorized data access, data modification, or deletion. Given that the attack vector is network-based (AV:N) with low attack complexity (AC:L) and no privileges or user interaction required, exploitation is straightforward. The vulnerability impacts confidentiality, integrity, and availability of the system's data, although the CVSS vector indicates a low impact on each (VC:L, VI:L, VA:L). The vulnerability has been publicly disclosed, increasing the risk of exploitation, although no known exploits are currently reported in the wild. The Inventory Management System is likely used to track and manage stock, users, and transactions, so exploitation could lead to significant operational disruption and data breaches. The absence of patches or mitigation links in the provided data suggests that organizations using this software must urgently implement compensating controls or seek vendor updates.

For European organizations using the affected Inventory Management System 1.0, this vulnerability poses a significant risk to business operations and data security. Successful exploitation could lead to unauthorized access to sensitive inventory and user data, potentially exposing personal data protected under GDPR. Data integrity could be compromised by unauthorized modifications, leading to inaccurate inventory records and financial discrepancies. Availability could also be impacted if attackers execute destructive SQL commands, causing system outages. This could disrupt supply chain management and operational continuity, especially for SMEs relying on this software for daily inventory tracking. The remote and unauthenticated nature of the exploit increases the risk of widespread attacks, particularly in sectors with limited cybersecurity resources. Additionally, public disclosure of the vulnerability may attract opportunistic attackers targeting vulnerable European businesses. The potential GDPR implications of data breaches could result in regulatory fines and reputational damage.

Given the lack of official patches, European organizations should immediately implement the following mitigations: 1) Employ Web Application Firewalls (WAFs) with rules designed to detect and block SQL injection attempts targeting the 'edituserName' parameter. 2) Restrict network access to the Inventory Management System to trusted IP addresses or VPNs to reduce exposure. 3) Conduct thorough input validation and sanitization on all user-supplied data, especially parameters used in SQL queries; if possible, modify the application code to use parameterized queries or prepared statements. 4) Monitor database logs and application logs for unusual queries or error messages indicative of injection attempts. 5) Regularly back up databases and test restoration procedures to minimize impact from potential data corruption or deletion. 6) Engage with the vendor to obtain patches or updates and plan for an upgrade path to a secure version. 7) Educate IT staff about this vulnerability and ensure incident response plans are updated to handle potential exploitation scenarios.
