Environment HTB: Full User & Root Flag Capture Through Exploitation
Captured both the user and root flags on the Environment HTB machine! We exploited Laravel 11.30.0 (PHP 8.2.28) vulnerabilities, including argument injection (CVE-2024-52301) and UniSharp Laravel Filemanager code injection. By bypassing authentication with `–env=preprod` and leveraging the profile upload feature, we executed a PHP reverse shell and retrieved the user flag via `cat user.txt`. For root access, we decrypted `keyvault.gpg` from the `.gnupg` directory to obtain credentials and exploited sudo with preserved BASH\_ENV by crafting a script that spawned a privileged shell, ultimately gaining full control of the system.
