Laravel - Remote Code Execution (CVE-2021-3129)

Laravel framework is affected by a Remote Code Execution, located in the /_ignition/execute-solution endpoint. The root cause of this vulnerability is insecure usage of PHP functions file_get_content() and file_put_content(), which can be used for log poisoning. The versions affected are below 8.4.2 release, with the ignition mode versions below 2.5.2 release.

The risk exists that a remote unauthenticated attacker can fully compromise the server in order to steal confidential information, install ransomware, or pivot to the internal network.

Sniper can gain unauthenticated Remote Code Execution on the target system and extract multiple artefacts as evidence.

Upgrade the Laravel framework to a version higher than 8.4.2 and upgrade ignition mode to a version higher or equal with 2.5.2.
