The panel detection vulnerability refers to the exposure of the login panel for unauthorized access attempts. In some configurations, the login panel can be detected by unauthorized users, allowing them to attempt to access restricted areas. This visibility of the login panel does not necessarily indicate a security breach, but it does highlight the system's configuration aspects. Detecting such panels is part of routine security assessments, ensuring the configuration aligns with best practices. While the presence of a panel visible to unauthorized users is not a defect, ensuring it goes unexploited requires careful monitoring.

Technically, the vulnerability is identified by looking for specific indicators in the HTTP response, such as certain HTML patterns and status codes. In this case, an endpoint at <code>{{BaseURL}}/contao/login</code> is observed, and the presence of terms like "Contao Open Source CMS" in the body and a successful 200 HTTP status code are indicative of the login panel's availability. These details help in discerning the presence of specific software setups that could be vulnerable if improperly configured. Such detection is crucial to preemptively identify potential unauthorized access points.

If exploited by a person with malicious intent, this vulnerability can lead to unauthorized access attempts on the Contao-powered applications. While the mere discovery of a login panel is not harmful, if it leads to further security lapses, it could result in data breaches or unauthorized modifications. Malicious users may try various techniques to crack credentials, especially if additional security measures like rate limiting or IP restrictions are not implemented. Such exploitation makes it crucial to detect and mitigate potential entry points.
