CVE-2025-27264 is a Local File Inclusion (LFI) vulnerability found in the Creativeitem Doctor Appointment Booking software, specifically affecting versions up to 1.0.0. The vulnerability arises from improper control over the filename parameter used in PHP include or require statements, allowing an attacker to manipulate the input to include arbitrary files from the server's filesystem. This can lead to the execution of unintended code or disclosure of sensitive files such as configuration files, password stores, or other critical data. The flaw is rooted in insufficient input validation and sanitization of user-supplied data that controls file inclusion. Since the vulnerability does not require authentication or user interaction, it can be exploited remotely by unauthenticated attackers. Although no known exploits are currently in the wild, the nature of PHP LFI vulnerabilities makes them attractive targets for attackers aiming to escalate privileges, execute arbitrary code, or pivot within a compromised network. The affected product is a niche healthcare appointment booking system, which may be deployed in clinics and hospitals, increasing the risk to sensitive patient data and healthcare operations. The lack of an official patch or fix at the time of disclosure necessitates immediate defensive measures by administrators.

The impact of CVE-2025-27264 can be severe for organizations using the affected Doctor Appointment Booking software. Exploitation can lead to unauthorized disclosure of sensitive information such as patient records, system configuration files, and credentials, violating confidentiality requirements. Attackers may also execute arbitrary code on the web server, potentially gaining full control over the affected system, leading to integrity and availability compromises. This can disrupt healthcare services, damage organizational reputation, and result in regulatory penalties due to data breaches. Given the healthcare context, the impact extends beyond IT systems to patient safety and trust. The vulnerability's ease of exploitation without authentication increases the risk of widespread attacks, especially if the software is internet-facing. Organizations worldwide that rely on this software for appointment management are at risk of targeted attacks aiming to steal data or disrupt operations.

To mitigate CVE-2025-27264, organizations should first check for any official patches or updates from Creativeitem and apply them immediately once available. In the absence of patches, administrators should implement strict input validation and sanitization on all parameters controlling file inclusion to ensure only allowed files or paths are processed. Employing a whitelist approach for included files is recommended. Restrict PHP include paths using configuration directives such as open_basedir to limit file system access. Web application firewalls (WAFs) can be configured to detect and block suspicious file inclusion attempts. Regularly audit and monitor server logs for unusual access patterns or errors related to file inclusion. Isolate the affected application in a segmented network zone to limit lateral movement if compromised. Additionally, consider replacing or upgrading the software if it is no longer maintained or supported. Educate developers and administrators on secure coding practices to prevent similar vulnerabilities.
