What is CVE-2019-16977?

The FusionPBX application, specifically in version 4.5.7 and earlier, contains a security flaw in 'app/extensions/extension_imports.php'. This flaw arises when an unsanitized 'query_string' parameter is processed from the URL, facilitating reflected XSS attacks. Attackers can exploit this vulnerability to execute malicious scripts in the context of the user's browser, potentially leading to data theft or session hijacking. Ensuring proper sanitization and validation of input parameters is critical to protect against such vulnerabilities.
