Winrar free pt code#
The code above depicts the spoofed response showing several possible attack vectors such as running applications, retrieving local host information, and running the calculator application. We attempted several different attack vectors to see what is feasible with this kind of access. This will put us into Zone 1 of the IE security zones. This Man-in-the-Middle attack requires ARP-spoofing, so we presume that a potential attacker already has access to the same network domain. Instead of intercepting and changing the default domain “” responses each time with our malicious content, we noticed that if the response code is changed to “301 Moved Permanently” then the redirection to our malicious domain “” will be cached and all requests will go to the “”.

Next, we attempted to modify intercepted responses from WinRAR to the user. User-Agent: Mozilla/4.0 (compatible MSIE 7.0 Windows NT 10.0 Win64 圆4 Trident/7.0. Looking at the request itself, we can see the version (5.7.0) and architecture (圆4) of the WinRAR application: GET /?language=English&source=RARLAB&landingpage=expired&version=570&architecture=64 HTTP/1.1 Additional alert that the user gets during the MiTM attack However, in experience, many users click “Yes” to proceed, to use the application. As the request is sent via HTTPS, the user of WinRAR will get a notification about the insecure self-signed certificate that Burp uses. We set up our local Burp Suite as a default Windows proxy and try to intercept traffic and to understand more about why this was happening and whether it would be possible to exploit this error. Microsoft MSHTML Remote Code Execution Vulnerability This window uses mshtml.dll implementation for Borland C++ in which WinRAR has been written. This was surprising as the error indicates that the Internet Explorer engine is rendering this error window.Īfter a few experiments, it became clear that once the trial period has expired, then about one time out of three launches of WinRAR.exe application result in this notification window being shown. We had installed and used the application for some period, when it produced a JavaScript error: Error that indicates WebBrowser JS parser inside of WinRAR We found this vulnerability by chance, in WinRAR version 5.70. After which a user may continue to use the applications with some features disabled.
