This happens due to improper sanitization of user input in the authentication process. A successful attack could lead to a complete system compromise with the attacker gaining the ability to read and write to the application&#8217;s database and <a href=\"https:\/\/www.ameeba.com\/blog\/cve-2023-48265-critical-unauthenticated-denial-of-service-and-remote-code-execution-vulnerability\/\"  data-wpil-monitor-id=\"34402\">execute code<\/a> with &#8220;NT AUTHORITYNetworkService&#8221; permissions.<\/p>\n<p><strong>Conceptual Example Code<\/strong><\/p>\n<p>Here is a conceptual example of how the <a href=\"https:\/\/www.ameeba.com\/blog\/cve-2023-50123-exploitable-vulnerability-in-hozard-alarm-system-sms-authentication\/\"  data-wpil-monitor-id=\"34935\">vulnerability might be exploited<\/a>:<\/p><div id=\"ameeb-3201768087\" 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<pre><code class=\"\" data-line=\"\">POST \/Authenticate HTTP\/1.1\nHost: vulnerable_server:8000\nContent-Type: application\/json\n{ &quot;username&quot;: &quot;admin&#039;; DROP TABLE users; --&quot;, &quot;password&quot;: &quot;password&quot; }<\/code><\/pre>\n<p>In this example, the attacker sends a malicious SQL statement via the username parameter, which could <a href=\"https:\/\/www.ameeba.com\/blog\/cve-2025-29905-sql-injection-vulnerability-in-telecontrol-server-basic-potentially-compromising-entire-systems\/\"  data-wpil-monitor-id=\"38135\">potentially delete the entire<\/a> users table from the database.
