description: |
`getent` is a utility that retrieves entries from administrative databases configured
via the Name Service Switch (NSS). If misconfigured with the SUID bit, it can be abused
to access sensitive databases such as `shadow`, which contains user password hashes,
including root's.

This can lead to local privilege escalation by leaking password hashes for offline cracking.

functions:
suid:
- code: |
# Leak root hash from /etc/shadow via getent SUID binary
./getent shadow root
- code: |
# Dump all hashes
./getent shadow
