Fun with FTP Logs

StumbleUpon Toolbar | No Comments

Had to do some work with ProFTPD logs today.  This script was created to get the date of last login of a user, or a list of multiple users, and return that data as a .csv file.  If you have customized the log formats, you may need to tweek the regex that breaks apart the line. 

get_last_login.pl

Several bits are incomplete, including the proper handling of timezone offsets and usage text in the help routine, but it works if you pass it a logfile and either a name or a namefile

$ get_last_login.pl --log=auth.log --namefile=username_list.txt > last_login.csv

or

$ get_last_login.pl --log=auth.log --name=am_user > last_login.csv

In doing this work, I noticed something fun, people are now trying SQL injection through FTP:

ProFTPD Default Installation [32717] ###.###.###.### [24/Feb/2013:00:16:23 -0500] "USER %') 
UNION SELECT 1,concat(0x7b,0x6d,0x64,0x35,0x7d,0x78,0x4d,0x70,0x43,0x4f,0x4b,0x43,0x35,0x49,0x34,0x49,0x4e,
0x7a,0x46,0x43,0x61,0x62,0x33,0x57,0x45,0x6d,0x77,0x3d,0x3d),NULL,NULL,concat(0x2f),concat(0x2f,0x62,0x69,
0x6e,0x2f,0x73,0x68) #" 331
