CVE-2025-68544 is a vulnerability classified under CWE-98, indicating improper control of filenames used in PHP include or require statements within Thembay's Diza product. This flaw allows remote file inclusion (RFI), where an attacker can manipulate the filename parameter to include a remote malicious PHP file, leading to remote code execution. The vulnerability affects versions of Diza up to 1.3.15. The CVSS 3.1 score is 7.5, with vector AV:N/AC:H/PR:L/UI:N/S:U/C:H/I:H/A:H, meaning the attack is network-based, requires low privileges, no user interaction, but has high attack complexity. Successful exploitation can compromise confidentiality, integrity, and availability of the affected system. The vulnerability arises from insufficient validation or sanitization of user-supplied input used in include/require statements, a common PHP security issue. No public patches or known exploits are currently available, but the risk is significant given the potential for full system compromise. Thembay Diza is a PHP-based application, likely used in web environments, making it a target for attackers aiming to gain unauthorized access or disrupt services. The vulnerability's presence in web-facing applications increases the attack surface and potential impact.

For European organizations, exploitation of this vulnerability could lead to severe consequences including unauthorized access to sensitive data, defacement or disruption of web services, and potential lateral movement within networks. Given the high confidentiality, integrity, and availability impacts, organizations could face data breaches, loss of customer trust, and regulatory penalties under GDPR. The attack complexity is high but not prohibitive, and the requirement for low privileges means that even limited access could be leveraged for full compromise. Industries relying on Thembay Diza for e-commerce or content management are particularly at risk. The disruption could affect business continuity and lead to financial losses. Additionally, compromised systems could be used as a foothold for further attacks against European infrastructure or supply chains. The lack of known exploits in the wild currently provides a window for proactive mitigation, but the threat remains significant.

Organizations should immediately audit their use of Thembay Diza and identify affected versions. Until a vendor patch is released, apply the following mitigations: 1) Implement strict input validation and sanitization on all parameters used in include/require statements to prevent injection of remote file paths. 2) Disable allow_url_include and allow_url_fopen directives in PHP configurations to prevent remote file inclusion. 3) Employ web application firewalls (WAFs) with rules to detect and block suspicious include/require patterns. 4) Restrict file system permissions to limit the impact of any file inclusion attempts. 5) Monitor logs for unusual requests targeting include parameters. 6) Plan for rapid deployment of vendor patches once available. 7) Conduct security awareness training for developers to avoid unsafe coding practices. 8) Use application-layer segmentation to isolate vulnerable components. These steps go beyond generic advice by focusing on PHP-specific configurations and proactive detection.
