Docker Tugtainer

Description

Tugtainer is a self-hosted app for automating updates of Docker containers. In versions prior to 1.16.1, the password authentication mechanism transmits passwords via URL query parameters instead of the HTTP request body. This causes passwords to be logged in server access logs and potentially exposed through browser history, Referer headers, and proxy logs. Version 1.16.1 patches the issue.

Analysis

Tugtainer versions before 1.16.1 transmit authentication credentials through URL query parameters rather than request bodies, causing passwords to be exposed in server logs, browser history, and proxy logs. This exposure allows attackers with access to these logs or cached data to obtain valid credentials for the Docker container management system. …
