CVE-2025-8381 is a SQL Injection vulnerability identified in version 1.0 of the Campcodes Online Hotel Reservation System. The vulnerability arises from improper sanitization or validation of the 'room_id' parameter in the /add_reserve.php script. An attacker can remotely manipulate this parameter to inject malicious SQL code, potentially altering the intended database queries. This can lead to unauthorized data access, data modification, or even deletion within the backend database. The vulnerability does not require user interaction and can be exploited remotely without authentication, increasing its risk profile. The CVSS 4.0 base score is 5.3 (medium severity), reflecting that while the attack vector is network-based and requires low attack complexity, it does require some privileges (PR:L) and results in low confidentiality, integrity, and availability impacts. However, the public disclosure of the exploit increases the likelihood of exploitation attempts. The vulnerability affects only version 1.0 of the product, and no patches or mitigations have been officially released yet. The absence of known exploits in the wild suggests limited active exploitation at present, but the public availability of exploit details could change this rapidly.

For European organizations using Campcodes Online Hotel Reservation System 1.0, this vulnerability poses a significant risk to the confidentiality and integrity of reservation data, including customer personal information and booking details. Successful exploitation could lead to unauthorized data disclosure, manipulation of reservation records, or disruption of booking services, potentially damaging customer trust and violating data protection regulations such as GDPR. The hospitality sector in Europe is a frequent target for cyberattacks due to the volume of personal and payment data processed. Additionally, compromised reservation systems could be leveraged as entry points for broader network intrusions. The medium severity rating suggests that while the impact is not catastrophic, the risk is non-negligible, especially given the public exploit disclosure and remote attack vector.

Specific mitigation steps include: 1) Immediate upgrade or patching of the Campcodes Online Hotel Reservation System to a version that addresses this vulnerability once available. If no patch exists, consider disabling or restricting access to the /add_reserve.php endpoint or the vulnerable parameter 'room_id'. 2) Implement Web Application Firewall (WAF) rules to detect and block SQL injection patterns targeting the 'room_id' parameter. 3) Conduct thorough input validation and parameterized queries or prepared statements in the application code to prevent SQL injection. 4) Monitor logs for unusual database query patterns or repeated access attempts to the vulnerable endpoint. 5) Restrict database user privileges to the minimum necessary to limit the impact of any injection attack. 6) For organizations unable to immediately patch, consider isolating the affected system from external networks or limiting access to trusted IP addresses. 7) Educate IT and security teams on the vulnerability and ensure incident response plans are updated to address potential exploitation scenarios.
