Questions

I have managed to crack into the smegol user and gained the root database password. However when I try and run this command :

mysql> create function do_system returns integer soname ’raptor_udf2.so’ ;

ERROR 1126 (HY000) : Can’t open shared library ’raptor_udf2.so’ (errno : 0 /usr/lib/mysql/plugin/raptor_udf2.so : file too short)

I have looked around the internet and had no luck on finding a solution. Currently looking at other ways round the problem as I am not sure if it’s a problem with something I have done or the VM.

got this error few hours ago, try to compile one the box or put your shared object here : /usr/lib/raptor_udf2.so

The post is really old but I’d like to give quick fix that already worked for me to help anyone else asking the question.
The problem is that your "/usr/lib/raptor_udf2.so" size is almost zero (I don’t know why XD) but You can try to replace it with the file "raptor_udf2.so" created while compiling the exploit. I assume that you used this one https://github.com/1N3/PrivEsc/blob/master/mysql/raptor_udf.c
