CVE-2025-8379 is a vulnerability identified in version 1.0 of the Campcodes Online Hotel Reservation System, specifically within the /admin/edit_room.php file. The issue arises from improper handling of the 'photo' argument, which allows an attacker to perform unrestricted file uploads. This vulnerability can be exploited remotely without requiring user interaction or authentication, as indicated by the CVSS vector (AV:N, AC:L, AT:N, UI:N, PR:H). However, the presence of PR:H (privileges required: high) suggests that the attacker must have high-level privileges, such as admin access, to exploit the vulnerability. The unrestricted upload flaw means that an attacker with sufficient privileges can upload arbitrary files, potentially including malicious scripts or executables, leading to remote code execution or system compromise. The CVSS score of 5.1 (medium severity) reflects the moderate impact and exploitation complexity. The vulnerability does not require user interaction and has a low attack complexity, but the requirement for high privileges limits the attack surface. No patches or mitigations have been publicly disclosed yet, and no known exploits are currently in the wild. Given the nature of the vulnerability, it primarily threatens the confidentiality, integrity, and availability of the affected system by enabling attackers to execute arbitrary code or disrupt service through malicious uploads. The vulnerability is critical in the context of the system's role in managing hotel reservations, where compromise could lead to data breaches, service disruption, or unauthorized access to sensitive customer information.

For European organizations operating or relying on the Campcodes Online Hotel Reservation System version 1.0, this vulnerability poses a significant risk. Hotels and hospitality businesses are prime targets for cybercriminals due to the sensitive personal and payment data they handle. Exploitation could lead to unauthorized access to customer data, including personally identifiable information (PII) and payment details, resulting in privacy violations and regulatory penalties under GDPR. Additionally, attackers could disrupt booking operations, causing financial losses and reputational damage. The requirement for high privileges to exploit the vulnerability suggests that insider threats or compromised administrative accounts are the most likely attack vectors. European organizations with inadequate internal access controls or weak credential management are particularly vulnerable. Furthermore, the hospitality sector in Europe is a critical infrastructure component for tourism-dependent economies, amplifying the potential economic impact. The lack of available patches increases the urgency for organizations to implement compensating controls to mitigate risk until an official fix is released.

1. Restrict administrative access: Enforce strict access controls and multi-factor authentication (MFA) for all administrative accounts to reduce the risk of privilege escalation or credential compromise. 2. Monitor file upload directories: Implement file integrity monitoring and restrict executable permissions on directories used for file uploads to prevent execution of malicious files. 3. Validate and sanitize uploads: Apply server-side validation to restrict allowed file types and sizes, and sanitize file names to prevent injection of malicious payloads. 4. Network segmentation: Isolate the reservation system from other critical network segments to limit lateral movement in case of compromise. 5. Regular audits and monitoring: Conduct frequent security audits and monitor logs for suspicious activities related to file uploads or admin actions. 6. Incident response readiness: Prepare and test incident response plans specifically addressing web application compromise scenarios. 7. Vendor engagement: Engage with Campcodes to obtain patches or updates and apply them promptly once available. 8. Temporary workaround: If possible, disable or restrict the vulnerable upload functionality until a patch is released.
