Laravel Framework < 5.5.41 / 5.6.x < 5.6.30 RCE

high Nessus Plugin ID 193333

Language:

Synopsis

A PHP library installed on the remote host is affected by a remote code execution vulnerability.

Description

The version of Laravel Framework installed of the remote host is prior to 5.5.41 or 5.6.x prior to 5.6.30. It is, therefore, affected by a remote code execution vulnerability due to 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.

Note that Nessus has not tested for this issue but has instead relied only on the application's self-reported version number. Also note that this plugin does not distinguish between PHP packages installed via the OS package manager, PHP packages installed via Composer, or other sources. As a result, packages provided by your OS package repository may have backported fixes that this plugin may incorrectly report as vulnerable. Please refer to the OS-specific plugins for CVE-2018-15133 to check for backported fixes.

Solution

Upgrade to Laravel Framework version 5.5.41, 5.6.30 or later.
