CVE-2025-14900 identifies a SQL injection vulnerability in CodeAstro Real Estate Management System version 1.0, specifically in the /admin/userdelete.php file under the Administrator Endpoint component. The vulnerability stems from insufficient input validation or sanitization of the 'ID' parameter, which is used in SQL queries to delete user records. An attacker with high privileges can remotely manipulate this parameter to inject arbitrary SQL commands, potentially leading to unauthorized data access, modification, or deletion. The attack vector is network-based (AV:N), requires low attack complexity (AC:L), no user interaction (UI:N), but does require high privileges (PR:H), indicating that only authenticated administrators or users with elevated rights can exploit it. The vulnerability impacts confidentiality, integrity, and availability to a limited extent (VC:L, VI:L, VA:L). Although no known exploits are currently active in the wild, the public disclosure increases the risk of future exploitation. The lack of vendor patches at the time of disclosure necessitates immediate defensive measures. The vulnerability does not affect the scope beyond the vulnerable component, and there are no indications of chained attacks or privilege escalation beyond the initial requirement. This vulnerability is typical of SQL injection flaws where input parameters are not properly sanitized before being concatenated into SQL statements, a common security oversight in web applications.

For European organizations using CodeAstro Real Estate Management System 1.0, this vulnerability poses a moderate risk primarily to data confidentiality and integrity. Exploitation could allow an attacker with administrative privileges to manipulate or delete user data, potentially disrupting business operations or causing data breaches involving sensitive client information. Given the real estate sector's reliance on accurate and confidential data, such an attack could lead to financial losses, reputational damage, and regulatory penalties under GDPR if personal data is compromised. The requirement for high privileges limits the likelihood of external attackers exploiting this vulnerability directly; however, insider threats or compromised administrator accounts could be leveraged. The availability impact is limited but could result in denial of service on administrative functions. The medium severity suggests that while the risk is not critical, it should not be ignored, especially in environments where administrative access controls are weak or where the software is exposed to untrusted networks.

1. Apply patches or updates from CodeAstro as soon as they become available to address the SQL injection vulnerability directly. 2. Until patches are released, implement strict input validation and sanitization on the 'ID' parameter at the web application firewall (WAF) or reverse proxy level to block malicious SQL payloads. 3. Restrict access to the /admin/userdelete.php endpoint by IP whitelisting or VPN-only access to limit exposure to trusted administrators. 4. Enforce the principle of least privilege by ensuring that only necessary users have administrative rights, and regularly audit these permissions. 5. Monitor logs for unusual SQL errors or suspicious activity around the user deletion function to detect potential exploitation attempts. 6. Conduct regular security assessments and code reviews focusing on input handling in administrative modules. 7. Educate administrators on secure credential management to prevent account compromise. 8. Consider deploying database activity monitoring tools to detect anomalous queries indicative of SQL injection attempts. These measures collectively reduce the risk of exploitation and limit the potential damage if an attack occurs.
