Esafenet CDG Arbitrary File Read Scanner

The CDGServer3 is widely used in organizations for ensuring the secure handling and management of digital documents. It is primarily utilized by IT security teams and system administrators to track, manage, and secure electronic files across various platforms. The software integrates with existing databases and file systems, offering a comprehensive solution for document protection. By providing detailed monitoring and control, it prevents unauthorized access and distribution of sensitive data. Companies employ this system to maintain compliance with regulatory requirements and to safeguard corporate information assets. It supports multiple users, enabling secure collaboration while ensuring data integrity.

An Arbitrary File Read vulnerability allows attackers to read sensitive files on a server that they should not have access to. This can expose critical information such as configuration files, user data, or other confidential documents. The unauthorized file download aspect of this vulnerability further amplifies the risk as attackers can potentially extract valuable data without the need for authentication. Once exploited, this vulnerability can lead to severe data breaches and compromise the overall security of the organization. The vulnerability often arises from weak access control policies and improper file handling mechanisms. Patching this vulnerability is crucial to prevent data leaks and unauthorized data access.

This vulnerability in the CDGServer3 occurs at the endpoint "/CDGServer3/SQL/MYSQL/create_SmartSec_mysql.sql". It's primarily an issue with how the software handles file requests, allowing unauthorized users to download specific files directly. The vulnerable parameter does not sufficiently validate user permissions, leading to unauthorized file access. This issue is particularly problematic as it uses common SQL file extension patterns, making it easier for attackers to identify and exploit. The software responds with a '200 OK' status if the file read operation is successful, with an SQL MIME type indicating the file type. Attackers can exploit this flaw to gain insight into the database structure or sensitive configurations.

Exploitation of the Arbitrary File Read vulnerability can result in significant data breaches and information disclosures. Critical files containing business-sensitive or personal identifiable information may be exposed to unauthorized parties. This can lead to not just operational disruption but also legal and regulatory implications. In severe cases, if files such as passwords and API keys are accessed, it could allow attackers to gain further access into the organization’s infrastructure. The reputation of the business may suffer due to potential data leaks, leading to loss of customer trust and financial damage.
