CVE-2023-0777 Scanner

Modoboa is an open-source email management software that includes a webmail interface, administration panel, and comprehensive mail server management capabilities. It is widely used by organizations and individuals to host and manage their email systems efficiently. Modoboa integrates with various email technologies to provide a streamlined experience for setting up and maintaining email servers, making it a popular choice for system administrators looking for a flexible and user-friendly email solution.

The vulnerability identified in Modoboa prior to version 2.0.4 involves an authentication bypass that could lead to an admin takeover. This critical security flaw allows attackers to gain unauthorized access to the admin panel of the Modoboa instance without valid credentials, posing a significant risk to the integrity and confidentiality of the hosted email systems.

Specifically, the vulnerability exploits a primary weakness in the authentication mechanism of Modoboa, where attackers can bypass the login process to access the admin dashboard. This issue is due to inadequate security measures in the authentication process, allowing attackers to use default or easily guessable credentials to gain admin privileges. The flaw affects all versions of Modoboa before 2.0.4, making it imperative for users to update their installations to ensure the security of their systems.

The exploitation of this vulnerability could lead to severe consequences, including unauthorized access to sensitive email data, configuration changes, account creation or deletion, and potentially the entire takeover of the email server. This would not only compromise the confidentiality and integrity of the email communications but could also lead to further attacks against users and associated networks.
