FE collaborative Office Directory Traversal Scanner

The yonyou FE collaborative office platform is widely used by organizations for efficient collaboration and document management in office settings. It facilitates seamless communication among team members, enabling them to share, edit, and manage documents collaboratively. The platform supports integration with various business applications, making it versatile for different business needs. Companies rely on this software to streamline their workflow, ensuring that all team members have access to the necessary documents and communications. Users can collaboratively work on projects in real-time, promoting productivity. However, like any software, it requires strict security measures to protect sensitive information.

Directory traversal vulnerabilities, like the one in yonyou FE collaborative office platform, enable attackers to access restricted directories and files. This vulnerability occurs when user input isn't properly sanitized, allowing attackers to traverse the file system. Through directory traversal, attackers can exploit underlying file directories to access unauthorized data. They can bypass access controls and potentially uncover confidential information stored on the server. Such vulnerabilities are commonly targeted by malicious actors to perform reconnaissance for further attacks. Proper input validation and directory access controls are crucial to prevent these vulnerabilities.

The vulnerability exists in the templateOfTaohong_manager.jsp endpoint of the yonyou FE collaborative office platform. The 'path' parameter in the endpoint is susceptible to directory traversal attacks, allowing unauthorized directory access. Using relative path sequences like "../..", attackers can explore directories outside the intended directory scope. The attack is confirmed when the application responds with directory listings or sensitive file contents. Attackers can leverage this vulnerability to read, write, or execute unintended files on the server. Proper mitigation requires tightening input validation and file access restrictions on this endpoint.

Exploiting a directory traversal vulnerability could lead to severe consequences, including unauthorized access to sensitive files and directories. Attackers could retrieve confidential information, configuration files, or even alter server data if the server has write permissions. This unauthorized access could facilitate additional attacks, such as privilege escalation or data exfiltration. In severe cases, attackers could use the acquired information to compromise the entire network. Preventative measures are essential to protect the integrity and confidentiality of the information hosted on the platform.
