CVE-2025-9848 is a security vulnerability identified in version 1.0 of the ScriptAndTools Real Estate Management System, specifically within an unspecified function in the /admin/userlist.php file. The vulnerability is characterized as an "execution after redirect" flaw, which allows an attacker to remotely execute code or commands after a redirect operation is performed by the application. This type of vulnerability typically arises when the application fails to properly terminate execution or validate state after issuing an HTTP redirect, potentially enabling an attacker to inject and execute malicious payloads in the context of the web application. The vulnerability requires no authentication, no user interaction, and can be exploited remotely over the network, making it accessible to unauthenticated attackers. The CVSS 4.0 base score is 6.9 (medium severity), reflecting the moderate impact on confidentiality, integrity, and availability, with low complexity and no privileges required. The vulnerability has been publicly disclosed but there are no known exploits actively observed in the wild at this time. The lack of available patches or mitigations from the vendor increases the risk for organizations still running the affected version. Given the nature of the affected system—a real estate management platform—successful exploitation could lead to unauthorized access to sensitive client and property data, manipulation of user accounts, or disruption of business operations through unauthorized code execution.

For European organizations using the ScriptAndTools Real Estate Management System version 1.0, this vulnerability poses a significant risk to the confidentiality and integrity of sensitive real estate data, including client personal information, property listings, and transaction records. Exploitation could lead to unauthorized data disclosure or modification, potentially violating GDPR and other data protection regulations, resulting in legal and financial penalties. Additionally, execution after redirect could be leveraged to pivot within the network or deploy further malicious payloads, impacting availability and operational continuity. Real estate firms, property management companies, and agencies relying on this software could face reputational damage and loss of client trust if exploited. The remote and unauthenticated nature of the vulnerability increases the attack surface, especially for externally accessible administrative interfaces. Given the critical role of real estate data in financial and legal transactions, the impact extends beyond IT to business and regulatory compliance domains.

1. Immediate mitigation should include restricting external access to the /admin/userlist.php endpoint through network segmentation, firewalls, or VPN access to limit exposure to trusted users only. 2. Implement web application firewall (WAF) rules to detect and block suspicious redirect patterns or payloads targeting this endpoint. 3. Conduct a thorough code review and patch the vulnerable function to ensure proper termination of execution after redirects and validate all inputs rigorously. 4. If vendor patches become available, prioritize timely application of updates. 5. Monitor logs for unusual activity related to redirects or unexpected execution flows in the admin interface. 6. Employ multi-factor authentication and strong access controls on administrative interfaces to reduce risk even if exploited. 7. Educate administrators on recognizing signs of exploitation and establish incident response plans specific to this vulnerability. 8. Consider migrating to updated or alternative real estate management solutions with active security support if patching is not feasible.
