An unauthenticated SQL injection vulnerability in Netartmedia Real Estate Portal 5.0 allows remote attackers to compromise backend database integrity and extract sensitive information.

The application is susceptible to SQL injection (CWE-89) because it fails to properly neutralize special elements in the page parameter during POST requests to index.php. This flaw allows an unauthenticated attacker to execute arbitrary SQL commands, potentially bypassing authentication mechanisms or accessing unauthorized data.

The ability for an unauthenticated user to execute arbitrary SQL queries represents a severe risk to data confidentiality and integrity. With a CVSS score of 8.2, this vulnerability could lead to the total exposure of user credentials, real estate listings, and administrative data, resulting in significant reputational damage and regulatory non-compliance.

Immediate Action: As no vendor patch is currently identified, administrators should restrict access to the application or disable the vulnerable index.php functionality if it is not business-critical.

Proactive Monitoring: Security teams should monitor web server logs for anomalous POST requests containing SQL keywords or characters such as single quotes, semicolons, and comment sequences directed at index.php.

Compensating Controls: Deploy a Web Application Firewall (WAF) with rules configured to detect and block SQL injection patterns specifically targeting the page parameter.

Public Exploit Available: Yes, a functional proof-of-concept exists as documented in the Exploit-DB entry 46563.

Given the high severity of this SQL injection vulnerability and the availability of public exploit code, immediate action is required to protect the application. If a vendor update is unavailable, isolating the portal from the public internet or implementing robust WAF filtering is essential to prevent unauthorized data extraction and system compromise.
