This vulnerability exists within the BroadVision One-To-One Enterprise web application platform, which is designed for enterprise content management and web publishing. The flaw represents a path traversal issue that occurs when the application processes requests for non-existent java server pages. When an attacker submits a request for a .jsp file that does not exist, the application reveals the physical server path where the web content is stored. This information disclosure vulnerability stems from the application's inadequate error handling mechanisms and its failure to sanitize user input properly before processing file requests. The vulnerability is classified under CWE-200 as "Information Exposure" and specifically relates to improper error handling that exposes system information. From an operational perspective, this vulnerability significantly weakens the security posture of affected systems by providing attackers with critical information about the server's file structure and directory layout.
The technical exploitation of this vulnerability occurs through simple HTTP requests that target non-existent .jsp files within the application's directory structure. When the web server encounters such requests, it generates error messages that inadvertently include the absolute physical path of the server files. This path disclosure can reveal sensitive information about the server's operating system, directory hierarchy, and potentially even the specific installation paths of the BroadVision application. The vulnerability is particularly dangerous because it requires minimal effort to exploit and can be automated through simple scripting tools. Attackers can leverage this information to plan more sophisticated attacks, including directory traversal attempts, file inclusion exploits, or to map the entire server filesystem structure. The vulnerability also aligns with ATT&CK technique T1083 "File and Directory Discovery" as it provides attackers with systematic access to server file system information.
The operational impact of this vulnerability extends beyond simple information disclosure, as it creates a foundation for more serious security breaches. Once an attacker has obtained the physical server paths, they can use this information to craft targeted attacks against the application or underlying system. The vulnerability can facilitate attacks such as local file inclusion or remote code execution if combined with other weaknesses in the application's architecture. Organizations running BroadVision One-To-One Enterprise are particularly at risk because this vulnerability can expose the complete directory structure of their web applications, potentially revealing sensitive configuration files, backup directories, or other system components that could be exploited. The vulnerability also violates security best practices established in standards such as NIST SP 800-53, which emphasizes the importance of protecting system information and preventing unauthorized access to sensitive data through proper error handling and input validation mechanisms.
Mitigation strategies for this vulnerability should focus on implementing proper error handling and input validation within the BroadVision application. Organizations should ensure that all error messages generated by the web application are generic and do not reveal system-specific information such as file paths, server names, or directory structures. The application should be configured to log detailed error information internally while displaying only generic error messages to end users. Additionally, implementing proper access controls and directory restrictions can help prevent unauthorized access to sensitive server directories. Security patches should be applied immediately if available from BroadVision, or alternative solutions such as web application firewalls should be deployed to filter out potentially malicious requests. Organizations should also conduct regular security assessments to identify similar vulnerabilities in their web applications and ensure that proper security controls are in place to prevent information disclosure attacks that could compromise their overall security posture.
