||Pegasus Mail remotely exploitable security hole
||3rd October 2000
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
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 "firstname.lastname@example.org" and
queues it ready to be sent without any further user intervention
If instead of "email@example.com" we have a local user,
"hacker" the message won't be queued but just sent immediately.
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.
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.
