TITLE:
ZoneAlarm Personal Firewall Program Control Feature Bypass

SECUNIA ADVISORY ID:
SA17450

VERIFY ADVISORY:
http://secunia.com/advisories/17450/

CRITICAL:
Not critical

IMPACT:
Security Bypass

WHERE:
Local system

SOFTWARE:
ZoneAlarm Anti-Spyware 6.x
http://secunia.com/product/6073/
ZoneAlarm Antivirus 6.x
http://secunia.com/product/6074/
ZoneAlarm Internet Security Suite 6.x
http://secunia.com/product/6072/
ZoneAlarm Pro 6.x
http://secunia.com/product/6071/

DESCRIPTION:
Debasis Mohanty has discovered a weakness in various ZoneAlarm
products, which can be exploited to bypass security features provided
by the product.

The weakness is caused due to the Program Control feature failing to
correctly identify and stop processes that use the Internet Explorer
browser to make outgoing connections via the "ShowHTMLDialog()" API
in MSHTML.DLL. This may be exploited by malware to send potentially
sensitive information out from an affected system.

The weakness has been confirmed in ZoneAlarm Pro 6.0.667 and reported
in the following products:
* ZoneAlarm Pro 6.0.x
* ZoneAlarm Internet Security Suite 6.0.x
* ZoneAlarm Anti-Spyware with Firewall 6.1.x
* ZoneAlarm Antivirus with Firewall 6.0.x

Note: The free version of ZoneAlarm Firewall does not support the
"Advanced Program Control" feature, and hence, does not prevent such
bypass techniques.

Secunia does not normally regard this kind of security bypass in
personal firewalls as a vulnerability. However, Secunia has decided
to write about this particular issue because Zone Labs is marketing
the product as being able to stop this kind of attack via the
"Advanced Program Control" functionality.

SOLUTION:
Do not run untrusted programs.
