Open WebUI Default Login Scanner

Open WebUI is a user interface framework used primarily by network administrators and developers. It facilitates management of web-based applications and resources across various platforms. Open WebUI's intuitive design allows customization, making it versatile for different environments, including corporate networks and private servers. Its widespread deployment in digital assets highlights the need for robust security controls to prevent unauthorized access. The software is regularly updated to patch vulnerabilities and improve user experience. Maintaining security is crucial to ensure the smooth operation of services and prevent potential data breaches.

The scanner detects the use of Open WebUI by checking for the presence of default credentials in its login panel. Default login vulnerabilities occur when applications are deployed with standard credentials, which attackers can exploit to gain unauthorized access. Detecting these vulnerabilities allows system administrators to enforce more secure configurations. The presence of default credentials in Open WebUI could allow an attacker to access administrative functionalities. Remediating this vulnerability is essential to maintain the integrity and security of the application.

The scanner interacts with the Open WebUI interface by sending a POST request to the authentication endpoint with default credentials. Upon successful authentication, the response contains JSON tokens that confirm access to the admin interface. This enables the verification of vulnerable installations of Open WebUI configured with default login details. The vulnerability is present when the application does not enforce stronger, unique passwords for administrative access. These technical details are critical for a comprehensive assessment and subsequent remediation.

If exploited, default login vulnerabilities can lead to unauthorized system access, data theft, or service disruption. Attackers may gain control over administrative functions, potentially resulting in remote code execution. This access jeopardizes sensitive data and can lead to further exploitation across interconnected systems. The use of default credentials poses significant security risks, making systems vulnerable to intrusions and malicious activities.
