It uses iconv, in php, in order to execute the same payload.

Uses cases :

You control the first parameter of iconv (in_charset), you can set an env var and you can upload arbitrary files (.so library file and the gconv-modules file) and you know their path.
You have a php RCE but system, shell_exec, curl_exec and other functions are disabled but you can setenv (and LD_PRELOAD is blacklisted).

How to have specific .gitignore for each git branch

Objective

My objective is to have some production files ignored on specific branches. Git doesn't allow to do it.

Solution

My solution is to make a general .gitignore file and add .gitignore.branch_name files for the branches I want to add specific file exclusion. I'll use post-checkout hook to copy those .gitignore.branch_name in place of .git/info/exclude each time I go to the branch with git checkout branch_name.
