CVE-2025-4267 is a SQL Injection vulnerability identified in SourceCodester's Stock Management System version 1.0, specifically within the Purchase Order Details Page component accessed via the /admin/?page=purchase_order/view_po endpoint. The vulnerability arises from improper sanitization or validation of the 'ID' parameter, allowing an attacker to inject malicious SQL code. This injection can be performed remotely without user interaction or authentication, as indicated by the CVSS vector, though the CVSS vector also notes a requirement for high privileges (PR:H), which suggests some level of authentication or elevated access may be necessary to exploit. The vulnerability could allow an attacker to manipulate backend database queries, potentially leading to unauthorized data access, data modification, or disruption of database integrity. Despite being classified as critical in the description, the CVSS 4.0 score is 5.1, which corresponds to a medium severity rating. The discrepancy may stem from the requirement of high privileges to exploit the vulnerability and limited scope or impact on confidentiality, integrity, and availability. No public exploits are currently known in the wild, but the vulnerability details have been disclosed publicly, increasing the risk of exploitation. No official patches or mitigation links have been provided yet, which means affected organizations must rely on other defensive measures until a fix is available.

For European organizations using SourceCodester Stock Management System 1.0, this vulnerability poses a significant risk to the confidentiality and integrity of their purchase order data. Exploitation could lead to unauthorized disclosure of sensitive procurement information, manipulation of purchase orders, or disruption of inventory management processes. This could result in financial losses, operational disruptions, and damage to business reputation. Given that the vulnerability requires high privileges, the risk is elevated primarily if internal accounts are compromised or if an insider threat exists. However, the remote attack vector means that if an attacker gains access to an administrative account or exploits other vulnerabilities to escalate privileges, they could leverage this SQL injection to further compromise the system. The lack of patches increases the urgency for organizations to implement compensating controls. Additionally, since stock management systems are critical for supply chain operations, exploitation could indirectly affect supply chain continuity, which is particularly sensitive in sectors like manufacturing, retail, and logistics prevalent across Europe.

1. Immediate mitigation should include restricting access to the /admin interface to trusted IP addresses or VPN-only access to reduce exposure. 2. Implement strict input validation and parameterized queries or prepared statements in the application code to prevent SQL injection, if source code access and modification are possible. 3. Monitor database logs and application logs for unusual query patterns or errors indicative of injection attempts. 4. Enforce the principle of least privilege for all user accounts, ensuring that administrative privileges are granted only when necessary and monitored closely. 5. Deploy Web Application Firewalls (WAFs) with rules specifically designed to detect and block SQL injection attempts targeting the vulnerable parameter. 6. Conduct internal audits and penetration testing to identify any privilege escalation paths that could be exploited to reach the high privilege level required for this attack. 7. Prepare for patch deployment by maintaining communication with the vendor or community for updates and applying patches promptly once available. 8. Educate administrative users about phishing and credential security to prevent account compromise that could lead to exploitation.
