DedeCMS Open Redirect Vulnerability Scanner

DedeCMS is a content management system that offers web developers and website owners a platform for building and managing websites. It is widely used due to its user-friendly interface and flexibility in designing web pages. This CMS is especially popular among small to medium-sized businesses, bloggers, and digital marketers who require an efficient way to manage their online content. Despite its numerous features and benefits, DedeCMS has been found to have vulnerabilities that could potentially compromise the security of websites using this platform.

The open redirect vulnerability in DedeCMS allows attackers to redirect users to malicious websites. This type of vulnerability is exploited by modifying URL parameters to redirect users unexpectedly to an attacker-controlled website. Such vulnerabilities can be used in phishing attacks to trick users into believing they are visiting a legitimate site, potentially leading to the theft of sensitive information or spreading malware.

The issue lies in the 'download.php' file, where the 'link' parameter is not properly validated. Attackers can encode malicious URLs into base64 and pass them through the 'link' parameter. When a user clicks on the manipulated link, the CMS processes the request and redirects the user to the attacker-specified URL. This behavior can be exploited to redirect users to phishing sites or pages that host malicious content.

Exploiting the open redirect vulnerability could lead to several adverse effects, including stealing users' sensitive information through phishing sites, infecting users' devices with malware, and damaging the reputation of the website using DedeCMS. It undermines the trust users have in the affected website and can lead to further security breaches if not addressed promptly.
