1 Intro

The Network File System (NFS) is a protocol that allows clients to access files on a server over the network. NFS is a common way to share files on Linux and Unix systems which usually have a client and server built into the operating system. It was originally developed by Sun in the 80s, currently there are multiple versions standardised in RFCs. Because of the long history behind NFS, the protocol has some very interesting security properties.

This wiki contains our research notes. If you want to exploit NFS misconfigurations or just want a better understanding of how NFS works, this is probably a good place to start. There will also be descriptions of attacks that can be performed on misconfigured Linux servers.

We will not cover the usage of the tools in the repo here in greater detail, this information is documented within the repository's README.md.
