Wuzhicms SQL Injection Scanner

Wuzhicms is a widely used open-source content management system employed by web developers and site administrators to easily build, manage, and optimize websites. Designed for flexibility and ease of use, it is often implemented in small to medium-sized enterprises and personal websites to deliver engaging digital experiences. With a myriad of functional modules and plugins, Wuzhicms allows for customization and scalability, supporting businesses and individuals in their digital transformation goals. Predominantly utilized by users who require a robust yet user-friendly CMS, it is recognized for its ability to handle content syndication, user management, and e-commerce functionalities. Administrators rely on Wuzhicms for streamlined content management while benefiting from its active community and support resources. Organizations often choose Wuzhicms due to its robust security features, but vulnerabilities can arise that require dedicated tools to identify and mitigate risks.

The SQL injection vulnerability in Wuzhicms 4.1.0 is a critical security flaw that allows attackers to execute arbitrary SQL commands via a vulnerable endpoint. It manipulates the 'grouppid' parameter at `/coreframe/app/member/admin/group.php`, which enables unauthorized access and modification of critical information stored in the database. This vulnerability is especially concerning as it allows attackers to retrieve sensitive information, such as user credentials or personal data, stored within the database. The flaw has a significant impact on the system's integrity, confidentiality, and availability, posing severe security risks if left unpatched. This form of injection is one of the most common web application vulnerabilities, often resulting from improper input validation on SQL statements. The severity of this vulnerability is rated high because of its potential to compromise the entire database structure and the potential misuse by external attackers.

The technical details of the SQL Injection vulnerability involve exploiting insufficient input sanitization processes in handling the 'grouppid' parameter within Wuzhicms. The endpoint `/api/sms_check.php` utilizes this parameter without proper validation, leaving it susceptible to injection attacks where attackers craft specific SQL queries. Attackers can exploit this endpoint by injecting a malformed SQL command that uses `updatexml` to reveal the result of a query, typically encoded in sensitive personal information. By using boolean-based query responses, attackers can determine the presence of certain data, bypassing authentication checks. This vulnerability may facilitate the injection of additional queries enabling an attacker to manipulate the backend database system, adding, deleting, or retrieving any data that their attack string specifies. The vulnerability can also be exploited through tool-based attacks provided SQL injection tools are configured with this vulnerability’s specific parameters.

If exploited, this SQL Injection vulnerability could result in unauthorized administrative operations, data breaches, and overall system compromise on the platform employing Wuzhicms 4.1.0. Attackers can obtain unauthorized access to sensitive data, including critical system configuration information and user details. Furthermore, it allows the execution of privileged commands on the database, altering stored content, or removing valuable records that could result in denial of service. The vulnerability may also allow attackers to escalate privileges and maneuver through other interconnected systems, resulting in a broader security breach. Recovery from an attack exploiting this vulnerability would require thorough forensic analysis, potentially significant data restoration efforts, and system reconfiguration, all contributing to substantial downtime and financial loss.
