Title: 3CX Phone System Multiple Cross Site Scripting Vulnerabilities

Severity: MODERATE

Description:

3CX Phone System is an IP PBX and SIP server available for Windows platform.

The web-based interface of the application is prone to multiple cross-site scripting vulnerabilities because it fails to sufficiently sanitize user-supplied data to the 'fName' and 'fPassword' form fields in the 'login.php' script.

An attacker may leverage these issues to execute arbitrary script code in the browser of an unsuspecting user in the context of the affected site. This may allow the attacker to steal cookie-based authentication credentials and to launch other attacks.

3CX Phone System 6.1793 is vulnerable; other versions may also be affected.

Affected Products:

  • 3CX Phone System 6.1793
