silverstripe/framework code execution vulnerability

High severity GitHub Reviewed Published May 27, 2024 to the GitHub Advisory Database

Package

composer silverstripe/framework (Composer)

Description

There is a vulnerability whereby arbitrary global functions may be executed if malicious user input is passed through to in the second argument of ViewableData::renderWith. This argument resolves associative arrays as template placeholders. This exploit requires that user code has been written which makes use of the second argument in renderWith and where user input is passed directly as a value in an associative array without sanitisation such as Convert::raw2xml().

ViewableData::customise is not vulnerable.

CVSS v3 base metrics

Attack vector: More severe the more the remote (logically and physically) an attacker can be in order to exploit the vulnerability.
Attack complexity: More severe for the least complex attacks.
Privileges required: More severe if no privileges are required.
User interaction: More severe when no user interaction is required.
Scope: More severe when a scope change occurs, e.g. one vulnerable component impacts resources in components beyond its security scope.
Confidentiality: More severe when loss of data confidentiality is highest, measuring the level of data access available to an unauthorized user.
Integrity: More severe when loss of data integrity is the highest, measuring the consequence of data modification possible by an unauthorized user.
Availability: More severe when the loss of impacted component availability is highest.
