Embedding untrusted input inside CSV files leads to Formula Injection/CSV Injection

High severity GitHub Reviewed Published May 10, 2023 in pimcore/customer-data-framework • Updated Nov 7, 2023

Package

composer pimcore/customer-management-framework-bundle (Composer)

Affected versions

< 3.3.9

Patched versions

3.3.9

Description

Impact

The pimcore application is vulnerable to Formula Injection/CSV Injection via the Firstname, Lastname, Street, Zip & City input fields. These vulnerabilities allow unauthenticated attackers to execute arbitrary code via a crafted excel file.

Successful exploitation can lead to impacts such as client-sided command injection, code execution, or remote ex-filtration of contained confidential data.

Patches

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.
