freePBX SIP protocol fields cross-site scripting
|freepbx-sip-xss (33772)||Medium Risk|
freePBX is vulnerable to cross-site scripting, caused by improper validation of user-supplied input by the Asterisk Log tool. A remote attacker could exploit this vulnerability using multiple SIP protocol fields, including the From, To, Call-ID, and User-Agent fields to inject malicious script into a Web page which would be executed in a victim's Web browser within the security context of the hosting Web site, once the page is viewed. An attacker could use this vulnerability to steal the victim's cookie-based authentication credentials.
Upgrade to the latest version of FreePBX (2.3 or later), available from the FreePBX Web site. See References.
