CVE-2025-11398 identifies a vulnerability in SourceCodester Hotel and Lodge Management System version 1.0, specifically within the /profile.php file's Profile Page component. The flaw arises from insufficient validation of the 'image' parameter, which allows an attacker to perform unrestricted file uploads. This means an attacker can remotely upload arbitrary files, including potentially malicious scripts, without requiring authentication or user interaction. The vulnerability's CVSS 4.0 score is 5.3 (medium), reflecting the network attack vector, low attack complexity, no privileges required, and no user interaction needed. The impact vector includes limited confidentiality, integrity, and availability impacts, as the uploaded files could be used to execute arbitrary code, deface the website, or disrupt services. Although no known exploits are currently active in the wild, public exploit code availability increases the risk of exploitation. The vulnerability is particularly dangerous in web-facing environments where the Hotel and Lodge Management System is deployed, as attackers could leverage this to gain persistent access or pivot within the network. The lack of patches or vendor-provided fixes necessitates immediate mitigation steps by administrators. This vulnerability is a classic example of improper input validation leading to unrestricted file upload, a common web application security issue that can lead to severe consequences if exploited.

For European organizations, especially those in the hospitality sector using SourceCodester Hotel and Lodge Management System 1.0, this vulnerability poses significant risks. Successful exploitation could lead to unauthorized remote code execution, allowing attackers to compromise sensitive customer data, including personal and payment information, violating GDPR requirements. It could also enable attackers to deface websites, disrupt booking operations, or use compromised servers as footholds for further attacks within the corporate network. The reputational damage and potential regulatory penalties from data breaches could be substantial. Given the hospitality industry's critical role in Europe's economy and the increasing reliance on digital management systems, this vulnerability could impact operational continuity and customer trust. Additionally, attackers might use the vulnerability to deploy ransomware or other malware, further escalating the impact. The medium severity rating suggests a moderate but non-negligible threat level, warranting timely remediation to prevent exploitation.

1. Implement strict server-side validation for file uploads, ensuring only allowed file types (e.g., JPEG, PNG) are accepted and verifying MIME types and file signatures. 2. Enforce file size limits and sanitize file names to prevent path traversal or overwriting critical files. 3. Disable file upload functionality in /profile.php if image uploads are not essential for business operations. 4. Use a separate storage location for uploaded files outside the webroot to prevent direct execution. 5. Employ web application firewalls (WAFs) to detect and block suspicious upload attempts targeting the 'image' parameter. 6. Monitor logs for unusual upload activity or unexpected file types. 7. Regularly audit and update the application and underlying server software. 8. If possible, isolate the affected system in a segmented network zone to limit lateral movement in case of compromise. 9. Engage with the vendor or community to obtain patches or updates addressing this vulnerability. 10. Educate IT staff on recognizing exploitation attempts and responding promptly.
