CWE Code: 502
Vulnerability Type: privilege_escalation
CVSS Score: 6.8
CWE Name:  Deserialization of Untrusted Data
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.
Access Authentication: NONE
Access Complexity: MEDIUM
Access Vector: NETWORK
Impact (C/I/A): PARTIAL/PARTIAL/PARTIAL
