Description
This security bulletin contains information about 1 security vulnerability.
1) Protection Mechanism Failure (CVE-ID: CVE-2020-13957)
The vulnerability allows a remote attacker to bypass implemented security restrictions.
The vulnerability exists due to insufficient implementation of security measures, configured in a ConfigSet that's uploaded via API without authentication/authorization. The checks in place to prevent such features can be circumvented by using a combination of UPLOAD/CREATE actions. A remote non-authenticated attacker can upload a specially crafted configuration and execute arbitrary code on the system.
