CVE-2025-12316 identifies a SQL Injection vulnerability in the Courier Management System version 1.0 developed by code-projects. The vulnerability resides in the /courier/edit-courier.php file, where the OfficeName parameter is improperly sanitized, allowing attackers to inject malicious SQL code remotely without authentication or user interaction. This injection can manipulate backend database queries, potentially exposing or altering sensitive courier data, disrupting service availability, or enabling further attacks such as privilege escalation or data exfiltration. The CVSS 4.0 vector indicates an attack vector of network (AV:N), low attack complexity (AC:L), no privileges required (PR:N), no user interaction (UI:N), and partial impacts on confidentiality, integrity, and availability (VC:L, VI:L, VA:L). Although no active exploitation has been observed, a public exploit is available, increasing the risk of future attacks. The vulnerability affects only version 1.0 of the product, and no official patches have been published yet. The lack of secure coding practices in input handling is the root cause, emphasizing the need for parameterized queries and input validation to prevent SQL injection. This vulnerability is critical for organizations relying on this system for courier management, as it could lead to data breaches or operational disruptions.

For European organizations using the affected Courier Management System 1.0, this vulnerability could lead to unauthorized access to sensitive courier and logistics data, including client information, shipment details, and operational records. The partial compromise of confidentiality, integrity, and availability could result in data leakage, unauthorized data modification, or service outages, impacting business continuity and customer trust. Logistics and courier companies are critical infrastructure components in Europe, and disruption could affect supply chains and delivery services. Additionally, regulatory compliance risks arise under GDPR due to potential exposure of personal data. The availability of a public exploit increases the likelihood of targeted attacks, especially against organizations with limited cybersecurity resources or outdated software. The medium severity rating suggests a significant but not catastrophic impact, yet the ease of remote exploitation without authentication makes it a notable threat vector.

Organizations should immediately assess their use of code-projects Courier Management System version 1.0 and prioritize upgrading to a patched version once available. In the absence of official patches, implement web application firewall (WAF) rules to detect and block SQL injection patterns targeting the OfficeName parameter. Conduct thorough input validation and sanitization on all user-supplied data, employing parameterized queries or prepared statements to prevent injection. Restrict network access to the management interface to trusted IP addresses and monitor logs for suspicious activity related to /courier/edit-courier.php. Regularly audit and review database permissions to minimize the impact of potential injections. Additionally, implement intrusion detection systems (IDS) with signatures for known exploits and educate staff on incident response procedures. Finally, consider isolating the affected system within segmented network zones to limit lateral movement in case of compromise.
