CVE-2025-60574 is a high-severity Local File Inclusion (LFI) vulnerability identified in tQuadra CMS version 4.2.1117. The vulnerability exists in the "/styles/" path, where the application fails to properly sanitize user-supplied input. This improper input validation allows an attacker to craft a GET request that exploits directory traversal sequences to access arbitrary files on the server's filesystem. The vulnerability is exploitable remotely over the network without requiring authentication or user interaction, increasing its risk profile. The CVSS 3.1 base score of 7.5 reflects a network attack vector (AV:N), low attack complexity (AC:L), no privileges required (PR:N), no user interaction (UI:N), unchanged scope (S:U), high confidentiality impact (C:H), and no impact on integrity or availability (I:N/A:N). The underlying weaknesses correspond to CWE-98 (Improper Control of Filename for Include/Require Statement in PHP Program) and CWE-22 (Path Traversal). Although no public exploits have been reported yet, the vulnerability could allow attackers to access sensitive configuration files, credentials, or other critical data stored on the server, potentially facilitating further attacks or data breaches. The lack of available patches at the time of publication necessitates immediate attention to input validation and monitoring for suspicious requests.

For European organizations, the exploitation of this LFI vulnerability could lead to unauthorized disclosure of sensitive information such as configuration files, database credentials, or personally identifiable information (PII). This exposure can compromise confidentiality and may serve as a foothold for subsequent attacks like privilege escalation or remote code execution if combined with other vulnerabilities. Organizations in sectors such as government, finance, healthcare, and critical infrastructure that rely on tQuadra CMS for web content management are particularly at risk. The breach of sensitive data could result in regulatory penalties under GDPR, reputational damage, and operational disruptions. Since the vulnerability requires no authentication and can be exploited remotely, the attack surface is broad, increasing the likelihood of targeted or opportunistic attacks within Europe.

1. Immediately implement strict input validation and sanitization on all user-supplied data, especially in URL parameters related to the "/styles/" path, to prevent directory traversal sequences (e.g., '../'). 2. Employ web application firewalls (WAFs) configured to detect and block suspicious requests containing path traversal patterns targeting the vulnerable endpoint. 3. Monitor web server logs for anomalous GET requests attempting to access sensitive files or unusual paths. 4. Restrict file system permissions for the web server process to limit access to only necessary directories and files, minimizing potential exposure. 5. Segregate sensitive data and configuration files outside the web root directory to reduce risk if LFI is exploited. 6. Stay alert for official patches or updates from tQuadra CMS vendors and apply them promptly once released. 7. Conduct regular security assessments and penetration testing focusing on input validation and file inclusion vulnerabilities. 8. Educate development and operations teams about secure coding practices related to file handling and input sanitization.
