The following excerpt is taken from a honeypot log that was hosted at lab.wiretrip.net. Snort
reported Unicode attacks from 213.116.251.162. The file Permission Canonicalization vulnerability
(UNICODE attack) allows scripts to be run in arbitrary folders that do not normally have the right to
run scripts. The attacker tries a Unicode attack and eventually succeeds in displaying boot.ini.
He then switches to playing with RDS, via msadcs.dll. The RDS vulnerability allows a malicious
user to construct SQL statements that will execute shell commands (such as CMD.EXE) on the IIS
server. He does a quick query to discover that the directory exists, and a query to msadcs.dll
shows that it is functioning correctly. The attacker makes a RDS query which results in the
commands run as shown below:
