ZZCMS Cross-Site Scripting Scanner

ZZCMS is a content management system used widely across various industries for managing and publishing web content. It is typically utilized by small to medium-sized businesses due to its user-friendly interface and flexibility. Organizations value ZZCMS for its cost-effectiveness and its range of features that support content creation, editing, and administration. Designed for ease of integration, it is employed by both technical and non-technical users for their web content needs. ZZCMS is often seen as a comprehensive solution for companies looking for robust content management capabilities. However, like other CMS platforms, it requires constant security audits to prevent vulnerabilities.

The scanner can identify the presence of a Cross-Site Scripting (XSS) vulnerability. XSS is a web security flaw that allows attackers to inject scripts into web pages viewed by other users. This vulnerability can be exploited to execute scripts in the context of the user's browser, potentially leading to session hijacking, defacement, or redirection to malicious sites. Detecting XSS vulnerabilities is crucial for maintaining the integrity of web applications. It can commonly occur in applications that do not properly validate or encode user inputs. By exploiting XSS, attackers can gain unauthorized access to session cookies or display unwanted content to end-users.

The vulnerability lies in the `register_nodb.php` endpoint of the ZZCMS application. The issue allows attackers to inject arbitrary scripts by supplying a malicious input payload. This specific XSS vulnerability manifests when user input is not properly sanitized, leading to execution of the injected script. The vulnerability can be triggered through a GET request that includes a crafted payload intended to exploit the script execution flaw.

Exploitation of this vulnerability can result in multiple adverse effects, including user data theft, unauthorized actions performed on behalf of a logged-in user, and malicious redirection. Attacks can escalate from stealing session cookies to causing reputational damage to the affected site. Furthermore, users might be exposed to phishing attacks where sensitive information like passwords can be compromised.
