CVE-2025-14530 is a vulnerability identified in SourceCodester Real Estate Property Listing App version 1.0, specifically in the /admin/property.php file. The vulnerability arises from insufficient validation of the 'image' parameter, allowing an attacker with high privileges to upload arbitrary files without restriction. This unrestricted upload flaw can be exploited remotely, enabling attackers to upload malicious files such as web shells or scripts that could compromise the server. The vulnerability does not require user interaction but does require the attacker to have high privileges (likely authenticated admin access), limiting the attack surface somewhat. The CVSS 4.0 vector indicates network attack vector (AV:N), low attack complexity (AC:L), no user interaction (UI:N), and no privileges required (PR:H), with low impact on confidentiality, integrity, and availability. Although no known exploits are currently in the wild, public disclosure increases the risk of exploitation. The lack of patch links suggests that a vendor fix may not yet be available, emphasizing the need for immediate mitigation. This vulnerability could lead to unauthorized code execution, data exposure, or service disruption if exploited.

For European organizations, especially those in the real estate sector using this application, the vulnerability poses a risk of unauthorized file uploads that could lead to server compromise, data breaches, or defacement of web properties. Compromise of the application server could impact confidentiality by exposing sensitive client or property data, integrity by allowing unauthorized modification of listings or data, and availability by enabling denial-of-service conditions through malicious payloads. The requirement for high privileges reduces the risk from external attackers but insiders or compromised accounts could exploit this vulnerability. Given the real estate sector's importance and the potential for sensitive personal and financial data exposure, the impact could be significant. Additionally, exploitation could serve as a foothold for lateral movement within corporate networks. The medium CVSS score reflects moderate risk but should not be underestimated given the potential consequences.

Organizations should immediately audit their use of SourceCodester Real Estate Property Listing App version 1.0 and restrict access to the /admin/property.php interface to trusted administrators only. Implement strict server-side validation of uploaded files, including checking MIME types, file extensions, and scanning for malicious content. Employ web application firewalls (WAFs) to detect and block suspicious upload attempts. Monitor logs for unusual file upload activity or access patterns. If possible, isolate the application server in a segmented network zone to limit lateral movement. Until an official patch is released, consider disabling file upload functionality or replacing it with a secure alternative. Regularly update and patch all components of the web application stack. Conduct security awareness training for administrators to prevent credential compromise. Finally, prepare incident response plans to quickly address any exploitation attempts.
