CVE-2018-15133
high · 8.1Actively exploitedOn the CISA Known Exploited Vulnerabilities catalog
Apply mitigations per vendor instructions or discontinue use of the product if mitigations are unavailable.
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.
