What is CVE-2023-54345?

The Frappe Framework ERPNext version 13.4.0 is susceptible to a sandbox escape vulnerability within RestrictedPython. This issue permits authenticated users with the System Manager role to execute arbitrary code by leveraging frame introspection. Specifically, an attacker can craft a server script through the /app/server-script endpoint and exploit the gi_frame attribute. This facilitates traversal of the call stack, allowing the execution of system commands via os.popen. Such a vulnerability poses significant risks to system integrity and data security.
