Duomi CMS SQL Injection Scanner

Duomi CMS is a versatile content management system predominantly used by webmasters and site developers to manage and publish digital content over the internet. This software is favored for its user-friendly interface and flexibility, allowing users to customize their sites to fit various purposes ranging from personal blogs to professional websites. By facilitating efficient content management, Duomi CMS attracts a wide audience that includes content creators, organizations, and developers looking to create interactive experiences on their sites. Users can extend the capabilities of Duomi CMS with plugins and extensions, enriching the platform with additional features and functionalities. As a widely deployed CMS, ensuring its security and stability is critical for preventing potential exploits that could compromise site integrity and data. Consequently, identifying and patching vulnerabilities like SQL Injection is crucial in maintaining a secure digital environment for Duomi CMS users.

SQL Injection (SQLi) is a critical security vulnerability that allows attackers to interfere with the queries that an application makes to its database. By manipulating input fields, an attacker can insert malicious SQL statements, potentially accessing sensitive data such as user credentials, altering or deleting database entries, or even executing administrative operations. In the case of Duomi CMS, this could compromise the site's integrity, leading to unauthorized access to user data and administrative functions. SQL Injection vulnerabilities are dangerous because they can be exploited remotely, requiring no prior access or authentication by the attacker. These vulnerabilities highlight the importance of rigorous input validation and sanitation in application development to prevent unauthorized data manipulation. In light of SQL Injection's potential impact, identifying and mitigating this vulnerability is a top priority for security-conscious developers and administrators.

The SQL Injection vulnerability in Duomi CMS is present within its AJAX handler, specifically affecting the "addfav" function through a particular GET request. The endpoint "/duomiphp/ajax.php?action=addfav&id=1&uid=1" is vulnerable, particularly when malicious SQL statements are appended to its parameters. An example of such a statement would involve using "extractvalue" function to test for the vulnerability by injecting an MD5 hash and expecting its return value. Through techniques like this, an attacker can determine the presence of the vulnerability and manipulate the database environment. The matchers configured to detect this vulnerability look for specific MD5 hash outputs and an HTTP status code 200, indicating a successful injection. Proper analysis and monitoring of these vulnerable parameters are essential for thwarting potential exploits that could lead to critical data breaches and unauthorized site access.

Exploiting the SQL Injection vulnerability in Duomi CMS can have severe consequences, ranging from the exposure of sensitive user information to full administrative access over the affected website. Attackers could leak confidential database contents, including user credentials, leading to privacy breaches and the potential for further attacks. The manipulation of database queries could allow adversaries to alter or delete records, cause data integrity issues, or create fraudulent entries. Furthermore, gaining administrative rights through this vulnerability could let attackers install malicious scripts, alter site content, or completely commandeer the website's operations. The ramifications can extend beyond a single site, causing downstream effects on user safety and brand reputation. Therefore, addressing SQL Injection vulnerabilities is essential to protect against data theft and maintain the trust between website operators and their users.
