Description
Frappe is a full-stack web application framework. Prior to 15.86.0 and 14.99.2, certain requests were vulnerable to path traversal attacks, wherein some files from the server could be retrieved if the full path was known. Sites hosted on Frappe Cloud, and even other setups that are behind a reverse proxy like NGINX are unaffected. This would mainly affect someone directly using werkzeug/gunicorn. In those cases, either an upgrade or changing the setup to use a reverse proxy is recommended. This vulnerability is fixed in 15.86.0 and 14.99.2.

Executive Summary

This vulnerability is a path traversal issue in the Frappe web application framework versions prior to 15.86.0 and 14.99.2. It allows an attacker to retrieve certain files from the server if they know the full path to those files. The vulnerability mainly affects setups that use werkzeug/gunicorn directly without a reverse proxy like NGINX. Sites hosted on Frappe Cloud or behind a reverse proxy are not affected.

Impact Analysis

If you are using Frappe without a reverse proxy and have not upgraded to versions 15.86.0 or 14.99.2 or later, an attacker could exploit this vulnerability to access sensitive files on your server by knowing their full path. This could lead to exposure of confidential information. Using a reverse proxy or upgrading the framework mitigates this risk.

Mitigation Strategies

To mitigate this vulnerability, you should upgrade Frappe to version 15.86.0 or 14.99.2 or later. Alternatively, if you are directly using werkzeug/gunicorn, you should change your setup to use a reverse proxy such as NGINX, as sites behind a reverse proxy are not affected.
