TITLE:
Ingate Firewall and SIParator Two Vulnerabilities

SECUNIA ADVISORY ID:
SA20479

VERIFY ADVISORY:
http://secunia.com/advisories/20479/

CRITICAL:
Moderately critical

IMPACT:
Cross Site Scripting, DoS

WHERE:
>From remote

OPERATING SYSTEM:
Ingate SIParator 4.x
http://secunia.com/product/5687/
Ingate Firewall 4.x
http://secunia.com/product/4050/

DESCRIPTION:
Two vulnerabilities have been reported in Ingate Firewall and
SIParator, which can be exploited by malicious people to conduct
cross-site scripting attacks and to cause a DoS (Denial of Service).

1) An error exists within the handling of SSL/TLS handshake in the
SIP module and in the web server. This can be exploited to cause the
modules to crash via a specially-crafted handshake.

Successful exploitation requires that SSL/TLS is enabled.

2) Input passed to unspecified parameters in the web interface isn't
properly sanitised before being returned to the user. This can be
exploited to execute arbitrary HTML and script code in an
administrator's browser session in context of the web interface.

SOLUTION:
Update to version 4.4.1.
