CVE-2025-11470 is a vulnerability identified in SourceCodester Hotel and Lodge Management System version 1.0, specifically within the /manage_website.php file. The vulnerability arises from improper handling of the website_image and back_login_image parameters, which allow an attacker with high privileges to upload arbitrary files without proper restrictions or validation. This unrestricted upload flaw can be exploited remotely, enabling attackers to potentially upload malicious scripts or files that could compromise the system's confidentiality, integrity, or availability. The vulnerability does not require user interaction but does require the attacker to have elevated privileges (PR:H), which limits the attack surface to authenticated users with high access rights. The CVSS 4.0 vector indicates no user interaction (UI:N), no scope change (SC:N), and partial impacts on confidentiality, integrity, and availability (VC:L, VI:L, VA:L). Although no public exploits have been observed in the wild, the vulnerability has been publicly disclosed, increasing the risk of future exploitation. The lack of vendor patches at the time of disclosure necessitates immediate mitigation efforts by administrators. This vulnerability is particularly concerning for hospitality organizations relying on this management system, as successful exploitation could lead to unauthorized code execution, data leakage, or service disruption.

For European organizations, especially those in the hospitality sector using SourceCodester Hotel and Lodge Management System 1.0, this vulnerability poses a moderate risk. Successful exploitation could allow attackers with high privileges to upload malicious files, potentially leading to unauthorized access, data tampering, or denial of service. Confidentiality could be compromised if sensitive customer or business data is accessed or exfiltrated. Integrity might be affected if attackers modify website content or system files. Availability could be impacted if malicious uploads disrupt normal operations or cause system crashes. Given the hospitality industry's reliance on customer trust and data protection, such incidents could result in reputational damage and regulatory penalties under GDPR. The requirement for high privileges reduces the likelihood of exploitation by external unauthenticated attackers but does not eliminate insider threats or attacks leveraging compromised credentials.

European organizations should implement strict access controls to limit who can upload files within the management system, ensuring only trusted administrators have high privileges. Validate and sanitize all uploaded files rigorously, restricting allowed file types and scanning for malware. Employ web application firewalls (WAFs) to detect and block suspicious upload attempts. Monitor logs for unusual upload activity or changes to website_image and back_login_image parameters. Since no official patches are currently available, consider isolating the affected system from public networks or restricting access via VPN or IP whitelisting. Regularly update and audit user privileges to minimize the number of users with high-level access. Engage with the vendor or community for updates or patches and apply them promptly once released. Additionally, conduct penetration testing focused on file upload functionalities to identify and remediate similar weaknesses.
