CVE-2023-37645 Scanner

EyouCms is a broadly utilized content management system, commonly employed by web developers for its ease of use in creating websites. The software is favored in areas where simplified content management is crucial, including personal blogs, small business portals, and information sites. Its user-friendly interface and rich features make it accessible for users with varying levels of technical expertise. Organizations and individuals use EyouCms to customize and manage web content efficiently without needing extensive technical skills. The software is built to ensure that non-technical users can easily update or manage their websites, promoting a straightforward approach to content management. Widely adopted across different regions, EyouCms delivers practical solutions for day-to-day website management tasks.

The information disclosure vulnerability in EyouCms arises when sensitive data is inadvertently exposed to unauthorized users. Such vulnerabilities may allow attackers to gain access to information that should otherwise be restricted, leading to potential privacy breaches. Typically found in improperly configured settings or through exposed endpoints, this form of vulnerability is often exploited to gain insights into the system's internal structures. In the context of EyouCms v1.6.3, the vulnerability is located within the component /custom_model_path/recruit.filelist.txt. Attackers may exploit this flaw to obtain access to sensitive data, impacting the confidentiality of the affected system. Regular assessments and proper configurations are essential to mitigate such risks and protect the integrity of the data within the CMS.

The technical details of the information disclosure vulnerability in EyouCms include the exposure of sensitive file paths through the endpoint /custom_model_path/recruit.filelist.txt. This endpoint can be accessed via HTTP GET requests and returns a 200 status code when exploited, indicating successful access to restricted data. The vulnerability requires no authentication, making it susceptible to exploitation from remote attackers with minimal effort. Specific indicators within the system's response, such as the presence of "application/admin/" and "template/pc/", reveal internal paths that can aid attackers in mapping the application's structure. Addressing the vulnerability involves restricting access to sensitive endpoints and enhancing input handling mechanisms to filter unauthorized information.

Exploiting this vulnerability could lead to unauthorized exposure of sensitive configuration files or internal paths, providing attackers with valuable insights into the system. Such exposures might facilitate further exploits, leading to additional security threats such as privilege escalation, data breaches, or unauthorized system manipulations. Malicious actors gaining insights into the system can tailor their attacks more precisely, targeting specific functions or files with high precision. Consequently, the organization may suffer reputational damage, loss of user trust, or financial repercussions stemming from unauthorized information access and potential subsequent attacks. Implementing robust security measures and regular audits will help minimize the chances of exploitation from such vulnerabilities.
