Sonarr Dashboard Security Misconfiguration Scanner

The Sonarr Dashboard is a web-based application used by individuals and organizations to manage and monitor TV show downloads from various media sources. It's primarily utilized by home network administrators and TV enthusiasts to automate the downloading process and organize TV content efficiently. The user-friendly interface allows for easy configuration and scheduling of downloads using predefined criteria. Although beneficial for personal usage, it is also used within entertainment companies to track and download large volumes of TV content. Integrating with multiple download clients, Sonarr provides a centralized platform for users who wish to manage TV shows across different devices. However, due to its open nature, it requires careful network configuration to prevent unauthorized exposure.

Unauthenticated access allows unauthorized users to gain unwanted access to the Sonarr Dashboard. This vulnerability typically occurs when access controls are not properly configured, allowing outsiders to view the dashboard without authentication. Once accessed, unauthorized users have the potential to view sensitive information, modify configurations, and disrupt the download and watching schedules. Unauthenticated access can stem from default permissions left unchanged or misconfigured access settings post-installation. Regularly, such issues are exploited through publicly accessible dashboards that have neglected proper security measures. This vulnerability emphasizes the need for strict authentication protocols to protect sensitive dashboard information.

Technically, this vulnerability is exploitable when the Sonarr Dashboard is exposed to the internet without proper authentication mechanisms in place. The primary point of weakness is the "/login" endpoint, which should prompt users for credentials, but in the case of misconfiguration, it allows access without verification. This makes the platform vulnerable as attackers can directly access the dashboard and bypass what would otherwise be restricted areas. Without prompts for a login screen, or if it is bypassable, users not part of the system can access information designed to be private. Parameters involved in session handling and user verification become irrelevant, making the system highly susceptible to unauthorized viewing. Therefore, securing endpoints and rigorous session management become imperative.

If exploited, malicious actors can access critical information stored or displayed on the Sonarr Dashboard, such as download activities, schedules, and user settings. They could modify or delete TV show entries, disrupting automated download schedules. Besides, exposure to network setups configured through the dashboard poses security risks by broadcasting sensitive configuration details like download paths and client communications. Potentially, attackers could alter configurations to route traffic through their servers for data interception. Such breaches could result in not only compromised downloads but also broader network vulnerabilities, compromising privacy and data integrity.
