CVE-2025-68984 is a critical security vulnerability classified as a Remote File Inclusion (RFI) flaw in the thembay Puca PHP program, affecting versions up to 2.6.39. The root cause is improper control over the filename parameter used in PHP's include or require statements, which allows an attacker to specify a remote file to be included and executed by the server. This vulnerability enables unauthenticated remote attackers to execute arbitrary PHP code on the affected server, potentially leading to full system compromise, data theft, defacement, or further network penetration. The vulnerability does not require any privileges or user interaction, making it highly exploitable over the network. The CVSS 3.1 base score of 9.8 reflects the critical nature of this flaw, with attack vector being network-based, low attack complexity, no privileges required, no user interaction, and high impact on confidentiality, integrity, and availability. Although no public exploits have been reported yet, the vulnerability's characteristics make it a prime target for attackers once exploit code becomes available. The vulnerability affects the thembay Puca product, which is a PHP-based program commonly used in web applications, including e-commerce and content management systems. The lack of patch links suggests that a fix may not yet be publicly available, emphasizing the need for immediate mitigation steps by affected users.

For European organizations, the impact of CVE-2025-68984 can be severe. Exploitation can lead to unauthorized remote code execution, allowing attackers to gain control over web servers hosting thembay Puca. This can result in data breaches involving sensitive customer or business data, website defacement, service disruption, or pivoting to internal networks for further attacks. Organizations in sectors such as e-commerce, government, and critical infrastructure that rely on PHP-based web applications are particularly at risk. The vulnerability's remote and unauthenticated nature increases the likelihood of widespread exploitation, potentially affecting availability of services and damaging organizational reputation. Additionally, compliance with GDPR and other data protection regulations could be jeopardized if personal data is compromised, leading to legal and financial penalties.

Immediate mitigation should focus on applying official patches from thembay once available. Until patches are released, organizations should implement strict input validation and sanitization on all user-supplied parameters that influence include or require statements. Disabling allow_url_include in the PHP configuration is critical to prevent remote file inclusion. Web application firewalls (WAFs) should be configured to detect and block suspicious requests attempting to exploit file inclusion. Regular code audits and security reviews of PHP applications can help identify and remediate similar vulnerabilities. Additionally, isolating the affected application environment and monitoring logs for unusual activity can help detect exploitation attempts early. Organizations should also maintain up-to-date backups to enable recovery in case of compromise.
