CVE-2025-67325 is a critical security vulnerability identified in QloApps, an open-source hotel booking and management software, specifically affecting versions 1.7.0 and earlier. The vulnerability arises from an unrestricted file upload flaw in the hotel review feature, which does not properly validate or restrict the types of files that can be uploaded by users. This lack of validation enables remote, unauthenticated attackers to upload malicious files, such as web shells or scripts, which can then be executed on the server, resulting in remote code execution (RCE). The vulnerability is classified under CWE-434 (Unrestricted Upload of File with Dangerous Type), highlighting the failure to restrict file types. The CVSS v3.1 score of 9.8 reflects the vulnerability's critical nature, with an attack vector of network (AV:N), no required privileges (PR:N), no user interaction (UI:N), and impacts on confidentiality, integrity, and availability (C:H/I:H/A:H). This means an attacker can fully compromise the affected system remotely without any authentication or user action. Although no public exploits are currently known, the vulnerability's characteristics make it highly exploitable. The absence of official patches at the time of publication increases the urgency for organizations to implement interim mitigations. The vulnerability's presence in a widely used hotel management platform poses a significant risk to organizations relying on QloApps, especially those exposing the review feature to the internet.

For European organizations, the impact of CVE-2025-67325 can be severe. Successful exploitation allows attackers to execute arbitrary code remotely, potentially leading to full system compromise, data theft, defacement, or use of the compromised server as a pivot point for further attacks within the network. Hospitality and tourism sectors, which heavily rely on QloApps for managing bookings and customer reviews, may face operational disruptions, reputational damage, and regulatory consequences under GDPR if customer data is exposed or manipulated. The critical nature of the vulnerability means attackers can bypass authentication and user interaction, increasing the risk of automated mass exploitation. Additionally, compromised systems could be used to launch attacks against other European infrastructure or serve as a foothold for cybercriminal groups. The lack of known exploits currently provides a window for proactive defense, but the high severity score indicates that once exploits emerge, rapid exploitation is likely. Organizations with public-facing hotel review features are particularly vulnerable, as these interfaces are accessible to unauthenticated users.

Given the absence of official patches at the time of disclosure, European organizations should immediately implement the following mitigations: 1) Disable or restrict the hotel review file upload feature until a patch is available. 2) Implement strict server-side validation to allow only safe file types (e.g., images) and reject executable or script files. 3) Enforce file size limits and scan uploaded files with antivirus and malware detection tools. 4) Apply web application firewall (WAF) rules to detect and block suspicious file upload attempts and anomalous HTTP requests targeting the review feature. 5) Restrict file upload directories with appropriate permissions to prevent execution of uploaded files. 6) Monitor logs for unusual activity related to file uploads and remote code execution attempts. 7) Conduct vulnerability scans and penetration tests focusing on the review feature to identify potential exploitation. 8) Prepare incident response plans to quickly isolate and remediate compromised systems. 9) Stay updated with QloApps security advisories and apply official patches immediately upon release. 10) Educate staff about the risks of this vulnerability and the importance of timely mitigation.
