Plone RestrictedPython < 5.3 / 6.x < 6.1 RCE

critical Nessus Plugin ID 329023

Synopsis

The remote host is affected by a remote code execution vulnerability.

Description

The version of RestrictedPython installed on the remote host is prior to 5.3, or 6.x prior to 6.1. It is, therefore, affected by a remote code execution vulnerability due to not checking access to stack frames and their attributes. An authenticated, remote attacker can exploit this to bypass authentication and execute arbitrary commands within the current stack frame.

Note that Nessus has not tested for these issues but has instead relied only on the application's self-reported version number.

Solution

Upgrade to RestrictedPython version 5.3, 6.1 or later.
