ISPConfig Hosting Control Panel Default Login Scanner

ISPConfig Hosting Control Panel is a commonly used web hosting control panel for managing multiple websites and associated services from a unified interface. It is favored by hosting providers and web developers for its ability to simplify web hosting management tasks. The software enables users to set up and manage web servers, email servers, and DNS settings efficiently. With its open-source nature, ISPConfig is accessible and customizable, appealing to both small-scale and enterprise-level operations. It supports multiple languages and works on various Linux distributions, thereby drawing a wide user base. However, like many web-based control systems, its security relies heavily on robust authentication mechanisms.

The default login vulnerability in ISPConfig Hosting Control Panel occurs when the software retains its initial default credentials after installation. This issue makes the control panel susceptible to unauthorized access by malicious users exploiting these predictable login details. The exploitability of this vulnerability is high since attackers can simply use common usernames and passwords to gain entry. Default login credentials are often indexed in automated scanning tools, making systems with unchanged default credentials major targets. This oversight can lead to significant breaches if not addressed promptly. As unauthorized access is achieved, the integrity of all systems managed under the control panel may be at severe risk.

In technical terms, the vulnerable parameter involves the login fields, specifically targeting administrative access using standard "admin/admin" credentials. The vulnerability is characterized by an HTTP POST request to the login endpoint "/content.php". If successful, the response header will return a status code of 200 and include a Set-Cookie header, indicating a successful login. Malicious users focusing on this exploit rely on the control panel's failure to enforce credential uniqueness upon the initial setup. Payloads comprising these default username-password combinations facilitate unauthorized access, allowing control over the server's web and email configurations.

When exploited, this vulnerability could allow attackers to manipulate website content, intercept email communication, and potentially escalate privileges to deploy further malicious activities across connected infrastructures. Sensitive data and user credentials could be exposed, leading to breaches of confidentiality and trust. Services managed by the compromised control panel could face downtime or unauthorized changes, impacting business operations and potentially causing financial losses. Continued unauthorized access could allow for persistent malware installation, creating ongoing security threats.
