CData API Server is a platform used by developers and organizations to connect, integrate, and automate workflows across various data sources and APIs. It is typically employed in environments requiring robust data integration capabilities, such as enterprise software solutions. Users leverage this server to build data-driven applications, enabling real-time data access and management. CData API Server supports a wide range of database and application connectors, facilitating seamless data operations. It is particularly useful in scenarios where data consolidation and API management are critical.
The Path Traversal vulnerability in CData API Server allows an unauthenticated remote attacker to access sensitive files and directories on the server. This can lead to complete administrative control over the application. The vulnerability is present in versions prior to 23.4.8844 and is considered critical due to its high impact on confidentiality, integrity, and availability. Exploiting this vulnerability does not require any authentication, making it a significant security risk.
The Path Traversal vulnerability exploits improper input validation in the CData API Server's handling of file paths. Specifically, the vulnerability is triggered when an attacker sends a crafted URL to access the getSettings.rsb endpoint using directory traversal sequences such as ..\. This allows the attacker to traverse the directory structure and access arbitrary files. The vulnerable endpoint /ui/..\src\getSettings.rsb?@json reveals sensitive information like configuration settings. The response includes JSON data with critical configuration items and the HTTP header indicates a successful exploitation.
Exploitation of this vulnerability can lead to unauthorized access to sensitive files and configuration settings. An attacker can gain complete administrative control over the CData API Server, potentially altering configurations, accessing confidential data, and disrupting service availability. This can lead to data breaches, loss of data integrity, and significant downtime. Additionally, the vulnerability can be exploited to escalate privileges and launch further attacks within the network.
