Summary

In Laravel Framework through 5.5.40 and 5.6.x through 5.6.29, remote code execution might occur as a result of an unserialize call on a potentially untrusted X-XSRF-TOKEN value. This involves the decrypt method in Illuminate/Encryption/Encrypter.php and PendingBroadcast in gadgetchains/Laravel/RCE/3/chain.php in phpggc. The attacker must know the application key, which normally would never occur, but could happen if the attacker previously had privileged access or successfully accomplished a previous attack.

Metasploit

description	This module exploits a vulnerability in the PHP Laravel Framework for versions 5.5.40, 5.6.x <= 5.6.29. Remote Command Execution is possible via a correctly formatted HTTP X-XSRF-TOKEN header, due to an insecure unserialize call of the decrypt method in Illuminate/Encryption/Encrypter.php. Authentication is not required, however exploitation requires knowledge of the Laravel APP_KEY. Similar vulnerabilities appear to exist within Laravel cookie tokens based on the code fix. In some cases the APP_KEY is leaked which allows for discovery and exploitation.
