LimeSurvey Default Login Scanner

LimeSurvey is a powerful survey management platform widely used by organizations of all sizes to create, conduct, and analyze surveys. Developed as open-source software, it facilitates the collection of feedback through customizable survey forms. The platform supports various question types, survey logic, and branching, making it a flexible tool for both simple and complex survey needs. With its extensive features and integration capabilities, LimeSurvey is utilized across industries such as education, research, marketing, and customer feedback. The user-friendly interface allows administrators to manage user roles and survey permissions, ensuring effective survey administration. To maintain security, LimeSurvey users are urged to change default credentials following installation.

This scanner detects instances where the LimeSurvey platform is using default administrator credentials, a critical security oversight. Default credentials can provide unauthorized users access to sensitive survey data and administrative functionalities, posing significant security risks. Upon detection, prompt resolution is necessary to mitigate any potential exploitation by malicious actors. Understanding the presence of default credentials is integral for maintaining a secure installation of LimeSurvey. This detection is part of fundamental security practices that help in safeguarding digital assets and sensitive information. Regular security audits using this scanner can prevent unauthorized access and maintain data integrity.

The scanner specifically targets the login endpoint of LimeSurvey and attempts to authenticate using known default credentials like "admin:password." Technical details include sending HTTP GET and POST requests to the login URL of LimeSurvey, capturing CSRF tokens if necessary, and evaluating the response for signs of successful login and access to administrative dashboards. The vulnerability lies in the failure to change these default credentials post-installation, which this scanner actively checks for. HTTP response codes are analyzed to confirm successful detections, such as a status code of 302 indicating a redirect to an admin panel. The presence of specific keywords in the response body or headers confirms vulnerability.

Exploiting this vulnerability allows attackers to access the administrative functionalities of LimeSurvey, enabling unauthorized survey management, user account manipulation, and potentially altering or accessing critical data. The compromise may result in data theft, survey alteration, and unauthorized data exports or deletions, significantly impacting organizational operations. Ensuring credentials are updated from defaults is crucial to mitigate these risks. Default login vulnerability represents a considerable threat vector that can cause data breaches if not identified and resolved promptly. Organizational reputation may be adversely affected in addition to operational disruptions.
