Summary
Laravel Framework, a popular PHP web application framework, is affected, and an attacker who knows the application's encryption key could run arbitrary code on the server by sending a crafted X-XSRF-TOKEN header. The attack requires the key, which is normally kept secret, so the risk mainly arises if an attacker already had privileged access or had compromised the application through another means.

Read the original description
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.
