Browser Security Flaws (NETSCAPE and IE):

"Son of Cache-Cow" Netscape Vulnerability

I've discovered yet another Netscape security hole. It appears to affect all versions of Communicator, including 4.07 which was just released to plug Cache-Cow.

The problem is that it's still possible to inject foreign JavaScript code into arbitrary documents. This has numerous evil applications. To illustrate some of them, I've written four exploitative programs. Follow the links to see the program source.

cookie-monster.cgi will steal cookies from arbitrary locations; this is very bad since cookies have been widely deployed for authentication purposes. The script will prompt you for a URL, and retrieve all cookies issued to you by that site.

file-list.cgi will steal the contents of a local directory on your hard drive.

The script will prompt you for a directory name, and retrieve the names of all the files contained it.

file-list-old.cgi is a version of file-list.cgi modified to work on Netscape 4.01.

cache-cow-4.07.cgi will steal the contents of your cache. It has precisely the same effect as the exploit announced last week.
...etc.

Cuartango security Hole

Affected software
Microsoft Internet Explorer 4
Microsoft Internet Explorer 5 Preview
I have not tested this IE 5 vulnerability but Chris Gayler of EngelSoft has sent me a note reporting IE 5 is also affected.

Fixes
Microsoft is thinking about. A hotfix will be released in the next few days. In the meantime I suggest you to listen this nice spanish music from the XVII century I have MIDI-coded for your entertainment.

Risks
Major : Your computer files can be sent to a WEB site by a malicious Script (if the file name is known).
Minor : The content of the clipboard can also be sent.
...etc.
