# 111 - NFS ### Network File System NFS is a distributed file system protocol for sharing over a network. Often used with UNIX operating systems and is predominantly insecure in its implementation. Portmapper and RPCbind both listen on port 111 and redirects clients to appropriate ports, often TCP 2049. #### Scan with nmap or use NSE scripts to locate NFS shares ``` nmap -v -p 111 10.11.1.1-254 nmap -sV -p 111 --script=rpcinfo 10.11.1.1-254 ``` #### Enumeration ``` nmap -p 111 --script nfs* $RHOST nmap -sV -p 111 --script=rpcinfo $RHOST nmap -p 111 --script nfs* 10.11.1.72 rpcinfo -p $targetip rpcbind $targetip ``` #### Mounting shares ``` showmount --exports $target_ip mount -o nolock $target_ip:/ /mnt ``` If files aren't readable, you may be able to create a new user, then use sed to change the UUID of the user to match the requirements (su username) --- # Agent Instructions: Querying This Documentation If you need additional information that is not directly available in this page, you can query the documentation dynamically by asking a question.
