Zzzcms Information Disclosure Scanner

Zzzcms is a content management system used widely for managing website content, providing powerful and easy-to-use tools for web developers and site administrators. Developed for businesses and individuals who require structured digital content, it optimizes website creation and maintenance processes. The software includes functionalities for publishing, editing, and modifying content as well as site maintenance from a central interface. Zzzcms is frequently utilized because of its customizable nature, allowing developers to modify templates and add plugins for extra features. Its open-source framework makes it accessible and efficient for both large-scale enterprises and small businesses. Despite its advantages, Zzzcms has had vulnerabilities which can sometimes grant unauthorized access to critical information.

Information Disclosure vulnerabilities occur when unauthorized information becomes accessible due to flaws in the application's architecture. In the case of Zzzcms, information from sensitive configuration files can be unintentionally exposed. These vulnerabilities commonly arise from improper file permissions or insufficient validations, which allow malicious actors to gain insights into the system configuration. Such disclosures could include admin paths or configuration settings, posing a security risk. Affected systems may reveal system components that are not intended to be public, potentially opening pathways for more elaborate attacks. This kind of weakness is especially concerning as it can disclose paths to vital components without any need for authentication.

This specific Information Disclosure vulnerability in Zzzcms version 1.75 allows unauthorized access to internal configuration files. The vulnerability is present in the plugins/webuploader/js/webconfig.php file, which can expose sensitive data from the zzz_config.php file. This exposure occurs because the file directly echoes content associated with the system's admin path. Unlike other vulnerabilities that require attack methods like brute-forcing, this disclosure provides the necessary information with a simple GET request. The endpoints reveal 'var adminpath' and 'var imageMaxSize', which can be potential indicators of system structure. The matching conditions for identifying this flaw include response status codes and specific words in the body and headers.

Exploitation of this vulnerability could lead to the exposure of confidential information regarding the web system's configuration and architecture. Such exposure might allow attackers to identify real administrative paths, potentially bypassing some security measures. Malicious actors can utilize this disclosed information to plan further intrusive operations, potentially leading to unauthorized access or data breaches. Knowledge of admin paths can be instrumental in constructing additional attacks like host header injections or privilege escalation. As these sensitive details are echoed without adequate restrictions, it makes the system vulnerable to exploitation and increases the risk of unauthorized actions being taken.
