CVE-2025-13302 identifies a SQL injection vulnerability in the Courier Management System version 1.0 developed by code-projects. The vulnerability resides in the /add-new-officer.php script, specifically in the handling of the ManagerName parameter. Due to insufficient input validation or sanitization, an attacker with high privileges can inject arbitrary SQL commands remotely, potentially manipulating the backend database. This could allow unauthorized retrieval, modification, or deletion of sensitive data stored within the system. The vulnerability does not require user interaction but does require the attacker to have elevated privileges, which limits the attack surface to insiders or compromised accounts. The CVSS 4.0 vector indicates network attack vector (AV:N), low attack complexity (AC:L), no authentication required (AT:N), but high privileges (PR:H) are necessary. The impact on confidentiality, integrity, and availability is low to medium, reflecting limited scope and privilege requirements. No patches have been published yet, and no known exploits are actively used in the wild, but a public exploit exists, increasing the risk of exploitation. The Courier Management System is typically used by logistics and courier companies to manage personnel and operations, making the data involved sensitive and critical to business continuity.

For European organizations, particularly those in the logistics and courier sectors, exploitation of this vulnerability could lead to unauthorized access to employee or operational data, manipulation of records, and potential disruption of courier services. This could result in data breaches involving personal or business-critical information, regulatory non-compliance (e.g., GDPR violations), and reputational damage. Operational disruptions could affect delivery schedules and customer satisfaction. Since the vulnerability requires high privileges, the risk is higher from insider threats or attackers who have already compromised privileged accounts. The availability of a public exploit increases the likelihood of opportunistic attacks if the system remains unpatched. Organizations relying on this software without adequate compensating controls are at increased risk.

1. Monitor vendor communications closely and apply security patches immediately once available. 2. Implement strict input validation and sanitization on all user-supplied data, especially parameters like ManagerName. 3. Enforce the principle of least privilege by restricting database user permissions to only what is necessary for application functionality. 4. Conduct regular audits of user accounts and privileges to detect and remove unnecessary high-privilege access. 5. Employ web application firewalls (WAFs) configured to detect and block SQL injection attempts targeting the vulnerable endpoint. 6. Monitor logs for suspicious database queries or unusual activity related to /add-new-officer.php. 7. Educate internal users about the risks of credential compromise and enforce strong authentication mechanisms to reduce insider threat risks. 8. Consider network segmentation to isolate critical systems and limit exposure.
