CVE-2025-69080 is a vulnerability classified under CWE-98, involving improper control of filenames used in PHP include or require statements within the JanStudio Gecko application. This vulnerability allows an attacker to perform Local File Inclusion (LFI), where arbitrary files on the server can be included and executed by the PHP interpreter. The flaw arises because the application does not sufficiently validate or sanitize user-supplied input that determines the filename to be included, enabling attackers to manipulate the input to reference sensitive files such as configuration files, password files, or application source code. Exploiting this vulnerability can lead to disclosure of sensitive information, code execution, and potentially full system compromise. The CVSS 3.1 base score is 8.1, indicating a high severity with network attack vector, high attack complexity, no privileges required, no user interaction, and impacts on confidentiality, integrity, and availability. The vulnerability affects all Gecko versions up to 1.9.8. No patches or known exploits are currently reported, but the risk remains significant due to the nature of LFI vulnerabilities in PHP applications. The vulnerability is particularly dangerous in web-facing environments where attackers can remotely send crafted requests to trigger the inclusion of local files. This can also be a stepping stone for further attacks such as remote code execution if combined with other vulnerabilities or misconfigurations.

For European organizations, the impact of CVE-2025-69080 can be severe. Organizations running JanStudio Gecko on their web servers risk unauthorized disclosure of sensitive data, including credentials, internal configuration, and user data. The ability to include arbitrary files can lead to remote code execution, allowing attackers to take full control of affected systems, disrupt services, or pivot within internal networks. This can result in data breaches, service outages, reputational damage, and regulatory penalties under GDPR. The high attack complexity somewhat limits exploitation but does not eliminate risk, especially for skilled attackers targeting critical infrastructure or high-value targets. The vulnerability's network accessibility and lack of required privileges make it a significant threat to public-facing web applications. European sectors such as finance, government, healthcare, and e-commerce, which rely heavily on PHP-based web applications, are particularly vulnerable. Additionally, the lack of available patches increases the window of exposure, necessitating immediate mitigation efforts.

1. Immediately audit all instances of JanStudio Gecko and identify affected versions (up to 1.9.8). 2. Implement strict input validation and sanitization on all user inputs that influence include/require statements, ensuring only allowed filenames or paths are accepted. 3. Disable dynamic inclusion of files based on user input wherever possible; use fixed include paths or whitelists. 4. Employ web application firewalls (WAFs) with rules to detect and block suspicious requests attempting LFI exploitation patterns. 5. Monitor logs for unusual file inclusion attempts or errors indicating exploitation attempts. 6. Isolate vulnerable applications in segmented network zones to limit lateral movement if compromised. 7. Prepare for patch deployment by maintaining contact with JanStudio for updates or security advisories. 8. Conduct code reviews and penetration testing focused on file inclusion vulnerabilities. 9. Educate developers and administrators about secure coding practices related to file inclusion in PHP. 10. Consider temporary mitigation by disabling or restricting PHP functions like include(), require(), or allow_url_include in php.ini if feasible without breaking functionality.
