Seeyon A6-M Arbitrary File Read Scanner

The Seeyon A6-M is an office collaboration platform widely used by enterprises for efficient management and coordination of tasks. It is primarily deployed in environments where seamless communication and file sharing are essential. The system is used by businesses to streamline their workflows and enhance productivity through its integrated suite of tools. Seeyon A6-M supports various forms of collaboration, including document management, scheduling, and task allocations. It is often chosen due to its robust features and flexibility in catering to different organizational needs. Companies rely on Seeyon A6-M to facilitate remote work and ensure operability across distributed teams, making it a pivotal part of their IT infrastructure.

The arbitrary file read vulnerability in Seeyon A6-M allows actors to access sensitive data stored on the server. This vulnerability is located in the `operaFileActionController.jsp` endpoint, which can be exploited to retrieve files without authorization. Such unauthorized access can lead to significant data breaches if sensitive or critical files are exposed. This vulnerability poses a security risk as it undermines the confidentiality and integrity of information within the organization's network. By targeting this weak point, attackers could compromise other systems and gain lateral movement within a network. It emphasizes the need for stringent security measures in protecting enterprise systems from unauthorized file access.

The technical details of this vulnerability involve the handling of file operations within the operaFileActionController interface. An improperly sanitized endpoint allows users to input arbitrary file paths and retrieve content without adequate authorization checks. The request involves HTTP GET operations targeting specific parameters associated with file paths within the server's filesystem. When exploited, the request returns HTTP 200 status, alongside the content of the file if the 'net.btdz.oa.system.fileTransfer.UserFileType' is confirmed in the body. This vulnerability specifically targets the loose file access control mechanisms of Seeyon A6-M and is a clear example of improper validation in web applications.

When exploited, this vulnerability can have detrimental effects such as unauthorized exposure of confidential data or sensitive internal communications. It could lead to data leaks where proprietary information like business strategies or customer data might be accessed by competitors or malicious actors. There is also a risk of data manipulation, potentially impacting business continuity if critical files are altered or deleted. Organizations could face financial losses and reputational damage due to compromised client information. Potential legal ramifications might also arise due to the failure in protecting customer data, leading to regulatory penalties or litigation.
