Technical Analysis

The Admin console includes a command to run shell commands. The GETrequest to cgi-bin/dna/sysAdmin.cgi requires administrative privileges on the account, however the POST command to run a command does not require authentication. Thus allowing an arbitrary command execution. Scripts were all written in perl, so a perl based payload is most safe.
