CVE-2018-15133
HIGH8.1⚠ KEVEPSS 84.4%Laravel Framework RCE Vulnerability
Published: 5/14/2022Modified: 1/13/2025Added to CISA KEV: 1/16/2024
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.
