Atheos is a self-hosted browser-based cloud IDE. Prior to v600, the $path and $target parameters are not properly validated across multiple components, allowing an attacker to read, modify, or execute arbitrary files on the server. These vulnerabilities can be exploited through various attack vectors present in multiple PHP files. This vulnerability is fixed in v600.

Directory traversal vulnerability in chroot function in AtheOS 0.3.7 allows attackers to escape the jail via a .. (dot dot) in the pathname argument to chdir.
