CVE-2025-14567 identifies a missing authentication vulnerability in the haxxorsid Stock-Management-System, affecting the /api/employees endpoint. This flaw allows unauthenticated remote attackers to access and manipulate employee-related data or functionality without any authentication or user interaction. The vulnerability exists in the version identified by commit fbbbf213e9c93b87183a3891f77e3cc7095f22b0, with no clear versioning due to the product's rolling release model. The vendor no longer supports this product, and no patches or updates have been issued despite early notification. The vulnerability's CVSS 4.0 vector (AV:N/AC:L/AT:N/PR:N/UI:N/VC:L/VI:N/VA:N/SC:N/SI:N/SA:N/E:P) indicates network attack vector, low attack complexity, no privileges or user interaction required, and partial confidentiality impact. The exploit code has been publicly released, increasing the risk of exploitation. The vulnerability could lead to unauthorized data disclosure or manipulation of employee records, potentially impacting business operations and compliance with data protection regulations. The lack of vendor response and patch availability necessitates alternative mitigation strategies.

For European organizations, this vulnerability poses significant risks including unauthorized access to sensitive employee information, potential data breaches, and operational disruptions in stock management processes. Exposure of employee data could lead to privacy violations under GDPR, resulting in legal and financial penalties. Unauthorized manipulation of stock or employee records could disrupt supply chains, inventory accuracy, and business continuity. Since the product is no longer supported, organizations cannot rely on vendor patches, increasing the likelihood of prolonged exposure. Attackers exploiting this vulnerability remotely can bypass authentication entirely, making it easier to compromise systems without insider access. The public availability of exploit code further elevates the threat level, potentially leading to targeted attacks against European companies using this system. The impact extends beyond confidentiality to integrity and availability of critical business functions.

Given the absence of vendor patches, European organizations should prioritize the following mitigations: 1) Immediately isolate the vulnerable haxxorsid Stock-Management-System from external networks using network segmentation and firewall rules to restrict access to the /api/employees endpoint. 2) Implement strict access controls at the network perimeter, allowing only trusted internal IPs or VPN connections to reach the system. 3) Deploy Web Application Firewalls (WAFs) with custom rules to detect and block unauthorized API requests targeting the vulnerable endpoint. 4) Monitor logs and network traffic for unusual or unauthorized access patterns related to the API, enabling rapid detection of exploitation attempts. 5) Where feasible, replace the unsupported system with a maintained alternative that includes proper authentication mechanisms. 6) Conduct regular security audits and penetration tests focusing on API security to identify similar weaknesses. 7) Educate IT and security teams about the vulnerability and the importance of restricting access to legacy systems. 8) Maintain up-to-date asset inventories to identify all instances of the vulnerable product within the organization.
