CVE-2025-14834 identifies a SQL injection vulnerability in the Simple Stock System version 1.0 developed by code-projects. The flaw resides in the /checkuser.php file, where the Username parameter is improperly sanitized, allowing an attacker to inject malicious SQL code remotely. This injection can manipulate backend database queries, potentially leading to unauthorized data disclosure, modification, or deletion. The vulnerability requires no authentication or user interaction, increasing its exploitation risk. The CVSS 4.0 base score is 5.3 (medium), reflecting the vulnerability's moderate impact on confidentiality, integrity, and availability, with low complexity and no privileges required. No official patches have been released yet, and no exploits are confirmed in the wild, but proof-of-concept code is publicly available, which could facilitate attacks. The affected product is a niche stock management system likely used by small to medium enterprises (SMEs) for inventory control. The vulnerability's exploitation could lead to data breaches, operational disruption, or further compromise of connected systems. The lack of segmentation or hardened input validation in the affected codebase is a key factor enabling this vulnerability. Organizations using this software should urgently assess exposure and implement mitigations.

For European organizations, the impact of CVE-2025-14834 depends on the extent of Simple Stock System deployment. SMEs using this software for inventory and stock management could face data breaches exposing sensitive business information, including user credentials or stock data. Integrity of inventory records could be compromised, leading to financial discrepancies or operational disruptions. Availability risks exist if attackers execute destructive SQL commands or cause database corruption. Given the vulnerability allows remote exploitation without authentication, attackers can launch attacks from anywhere, increasing the threat landscape. This could also serve as a foothold for lateral movement within corporate networks. The medium severity score reflects moderate but tangible risks to confidentiality, integrity, and availability. European SMEs, which form a significant part of the economy, may be disproportionately affected due to limited cybersecurity resources and reliance on such third-party software. Furthermore, regulatory frameworks like GDPR impose strict data protection requirements, so exploitation leading to data breaches could result in legal and financial penalties.

1. Immediate mitigation should focus on applying any available vendor patches or updates once released. 2. In the absence of patches, organizations should implement web application firewalls (WAFs) with specific rules to detect and block SQL injection attempts targeting the /checkuser.php endpoint and the Username parameter. 3. Conduct a thorough code review of the Simple Stock System source code to identify and sanitize all user inputs, especially those interacting with SQL queries, using parameterized queries or prepared statements. 4. Restrict database user privileges to the minimum necessary to limit the impact of any successful injection. 5. Monitor logs for unusual database query patterns or failed login attempts that may indicate exploitation attempts. 6. Segment the network to isolate the stock system from critical infrastructure and sensitive data repositories. 7. Educate IT staff and users about the risks and signs of SQL injection attacks. 8. Consider replacing or upgrading to more secure inventory management solutions if the vendor does not provide timely fixes.
