Hi Avivra, I have tested your PoC with Opera 9.52 and Opera 9.60 and I needed to tweak your scripts and it works. Good job! I mostly focused on stealing history and initially I could not find a way to interact with opera:config. But apparently, appending the IFRAME to the document DOM with document.body.appendChild is the way.

Instead of changing the HTTP Proxy, an attacker can change the default external mail application to "\\evil\malware.exe ", or to local commands (e.g. ftp.exe which can be used to download malicious binaries from remote). Also, there is a need to change the "Mail Handler" settings to "2", so opera will execute the external mail application, instead of the default opera mail application. After changing the settings, the attacker can simply set the location to "mailto:" to execute the code. A proof-of-concept which executes the Windows Calculator can be found here: http://raffon.net/research/opera/history/op.html Cheers, --Aviv. http://aviv.raffon.net Internal Virus Database is out of date.
