CVE-2025-6842 is a SQL Injection vulnerability identified in version 1.0 of the code-projects Product Inventory System, specifically within the /admin/edit_user.php file. The vulnerability arises from improper handling of the 'ID' parameter, which allows an attacker to inject malicious SQL code. This injection flaw can be exploited remotely without user interaction or authentication, although the CVSS vector indicates a requirement for high privileges (PR:H), suggesting that some level of authentication or elevated access might be necessary to exploit the vulnerability. The vulnerability impacts the confidentiality, integrity, and availability of the underlying database, potentially allowing attackers to read, modify, or delete sensitive data stored within the inventory system. The CVSS 4.0 score is 5.1, categorized as medium severity, reflecting limited impact due to required privileges and low scope change. No public exploit is currently known to be in the wild, but the exploit details have been disclosed publicly, increasing the risk of future exploitation. The absence of patches or mitigation links indicates that the vendor has not yet released an official fix, leaving systems vulnerable if not otherwise protected. Given the nature of the vulnerability in an administrative interface, successful exploitation could lead to unauthorized data manipulation or leakage within organizations using this product for inventory management.

For European organizations utilizing the code-projects Product Inventory System 1.0, this vulnerability poses a significant risk to the security of their inventory and user data. Exploitation could lead to unauthorized access to sensitive business information, including product details, user credentials, and potentially financial data. The compromise of data integrity could disrupt business operations, cause financial losses, and damage organizational reputation. Furthermore, unauthorized data disclosure could lead to violations of the EU General Data Protection Regulation (GDPR), resulting in legal penalties and fines. Since the vulnerability requires high privileges, insider threats or compromised administrative accounts could be leveraged by attackers to exploit this flaw. The lack of available patches increases the urgency for organizations to implement compensating controls. The medium severity rating suggests that while the vulnerability is serious, it may not be trivially exploitable by external attackers without some level of access, somewhat limiting the attack surface. However, given the critical role of inventory systems in supply chain and operational continuity, any disruption or data breach could have cascading effects on European businesses, especially in sectors reliant on accurate inventory management such as manufacturing, retail, and logistics.

European organizations should immediately conduct an inventory to identify any deployments of code-projects Product Inventory System version 1.0. Until an official patch is released, organizations should implement strict access controls to limit administrative interface access to trusted personnel only, ideally through network segmentation and VPNs with multi-factor authentication. Web application firewalls (WAFs) should be configured to detect and block SQL injection patterns targeting the 'ID' parameter in /admin/edit_user.php. Regular monitoring and logging of administrative actions can help detect suspicious activity early. Organizations should also consider temporarily disabling or restricting access to the vulnerable administrative functionality if feasible. Additionally, applying database-level permissions to limit the impact of potential SQL injection can reduce risk. As soon as a vendor patch becomes available, prompt testing and deployment are critical. Finally, organizations should educate administrators about the risks of credential compromise and enforce strong password policies to prevent privilege escalation that could facilitate exploitation.
