CVE-2025-32302 is a high-severity vulnerability classified under CWE-98, which pertains to improper control of filenames used in include or require statements within PHP programs. Specifically, this vulnerability affects the Gavias Winnex product up to version 1.3.2. The flaw allows an attacker to exploit PHP Remote File Inclusion (RFI) or Local File Inclusion (LFI) vectors by manipulating the filename parameter that is used in include or require statements without proper validation or sanitization. This can lead to the inclusion and execution of arbitrary files on the server, potentially resulting in remote code execution, data disclosure, or full system compromise. The CVSS 3.1 base score of 8.1 reflects the high impact on confidentiality, integrity, and availability, with network attack vector, no privileges required, no user interaction, but high attack complexity. No known exploits are currently reported in the wild, and no patches have been linked yet, indicating that the vulnerability is newly disclosed and may require immediate attention from affected parties. The vulnerability arises from the failure to properly validate or restrict the input controlling the file path in PHP include/require statements, a common and critical security issue in web applications that rely on dynamic file inclusion.

For European organizations using Gavias Winnex, this vulnerability poses a significant risk. Successful exploitation could allow attackers to execute arbitrary code on web servers, leading to unauthorized access to sensitive data, defacement of websites, or use of compromised servers as pivot points for further attacks within the network. Given the high confidentiality, integrity, and availability impacts, critical business operations relying on affected systems could be disrupted. This is particularly concerning for organizations in sectors such as finance, healthcare, government, and e-commerce, where data protection and service continuity are paramount. Additionally, the ability to remotely execute code without authentication increases the risk of widespread exploitation if the vulnerability is weaponized. The lack of patches and known exploits suggests a window of exposure where attackers could develop and deploy exploits targeting European entities, especially those with public-facing web applications running the vulnerable software.

European organizations should immediately audit their environments to identify any deployments of Gavias Winnex up to version 1.3.2. Until official patches are released, mitigation should focus on restricting access to vulnerable endpoints through web application firewalls (WAFs) with rules blocking suspicious include/require parameter manipulations. Input validation and sanitization should be enforced at the application level to prevent injection of arbitrary file paths. Disabling remote file inclusion in PHP configurations (e.g., setting allow_url_include to Off) can reduce risk. Organizations should also monitor logs for unusual requests targeting include/require parameters and implement network segmentation to limit lateral movement if a compromise occurs. Once patches become available, prompt application of updates is critical. Additionally, conducting penetration testing and code reviews to identify similar insecure coding patterns can help prevent future vulnerabilities.
