CVE-2025-9757 is a SQL Injection vulnerability identified in version 1.0 of the Campcodes Courier Management System, specifically within the Login function of the /ajax.php file. The vulnerability arises due to improper sanitization or validation of the 'email' parameter, allowing an attacker to inject malicious SQL code remotely without requiring authentication or user interaction. This flaw enables an attacker to manipulate backend database queries, potentially leading to unauthorized data access, data modification, or even complete compromise of the database. The vulnerability has a CVSS 4.0 base score of 6.9, indicating a medium severity level, with an exploitability rating of low complexity and no privileges or user interaction required. Although no known exploits are currently reported in the wild, the public disclosure of the vulnerability increases the risk of exploitation. The affected system is a courier management platform, which typically handles sensitive logistics, client, and shipment data, making the integrity and confidentiality of its database critical. The lack of a patch link suggests that a fix may not yet be available, emphasizing the need for immediate mitigation efforts.

For European organizations utilizing the Campcodes Courier Management System 1.0, this vulnerability poses a significant risk to the confidentiality and integrity of sensitive operational data, including customer information, shipment details, and internal logistics records. Exploitation could lead to unauthorized data disclosure, data tampering, or disruption of courier services, potentially causing operational delays and reputational damage. Given the critical role of courier services in supply chain and e-commerce sectors across Europe, such a compromise could have cascading effects on business continuity and customer trust. Additionally, data breaches involving personal data could trigger regulatory scrutiny under GDPR, leading to legal and financial penalties. The remote and unauthenticated nature of the attack vector increases the threat level, as attackers can exploit the vulnerability without insider access or user interaction.

Immediate mitigation should focus on implementing input validation and parameterized queries or prepared statements within the Login function to prevent SQL injection. Organizations should audit the /ajax.php file and any other input handling code for similar vulnerabilities. If a vendor patch becomes available, it should be applied promptly. In the absence of an official patch, deploying Web Application Firewalls (WAFs) with rules specifically designed to detect and block SQL injection attempts targeting the 'email' parameter can provide temporary protection. Additionally, monitoring database logs for unusual query patterns and implementing strict access controls to the database can help detect and limit the impact of exploitation. Regular security assessments and code reviews should be conducted to identify and remediate similar vulnerabilities. Finally, organizations should ensure that backups are current and tested to enable recovery in case of data compromise.
