Improper Limitation of a Pathname to a Restricted Directory ('Path Traversal')

CVE-2022-35918

Severity Medium
Score 6.5/10

Summary

Streamlit is a data oriented application development framework for python. Users hosting Streamlit app(s) that use custom components are vulnerable to a directory traversal attack that could leak data from their web server file-system such as: server logs, world readable files, and potentially other sensitive information. An attacker can craft a malicious URL with file paths and the streamlit server would process that URL and return the contents of that file or overwrite existing files on the web-server. This issue has been resolved in version 1.11.1rc1. Users are advised to upgrade. There are no known workarounds for this issue.

CWE-22 - Path Traversal

Path traversal (or directory traversal), is a vulnerability that allows malicious users to traverse the server's root directory, gaining access to arbitrary files and folders such as application code & data, back-end credentials, and sensitive operating system files. In the worst-case scenario, an attacker could potentially execute arbitrary files on the server, resulting in a denial of service attack. Such an exploit may severely impact the integrity, confidentiality, and availability of an application.
