OrbiTeam BSCW Server Local File Inclusion Scanner

OrbiTeam BSCW Server is used as a collaborative workspace system, enabling teams to manage documents, tasks, and communications securely. It is widely utilized by organizations across various sectors including education, healthcare, and business for effective team collaboration. The platform facilitates document sharing, version control, and project management, ensuring smooth information flow among team members. It can be deployed on-premises, offering customizable and secure collaboration solutions. BSCW Server is valued for its modularity and support for standards, integrating seamlessly into existing IT infrastructures. The software aids in productivity enhancement by providing tools for task management, scheduling, and team communication.

The Local File Inclusion (LFI) vulnerability occurs when an application includes files on the server, without properly sanitizing user input paths. This vulnerability can be exploited by malicious users to gain unauthorized access to sensitive server files, potentially leading to information disclosure. LFI flaws are often found within web applications that dynamically include scripts or resources. This vulnerability arises due to improper validation of input parameters, allowing attackers to traverse directories and access restricted files. LFI can lead to a breach of confidentiality as it can expose configuration files, passwords, and other sensitive data. The exploitation of this flaw can also assist attackers in executing further attacks, compromising the system's integrity.

Technical details of the LFI vulnerability in the OrbiTeam BSCW Server include improper validation of the 'style_name' parameter in the 'bscw.cgi' script. By crafting malicious requests, attackers can manipulate this parameter to traverse directories and access system files such as '/etc/passwd'. The application fails to sanitize user inputs to restrict access to legitimate paths, leading to a potential breach. The vulnerable endpoint is accessible unauthenticated, amplifying the risk of exploitation. This vulnerability is primarily due to inadequate input handling mechanisms within the server application. Attackers exploiting this flaw can gain insights into the system’s backend, paving the way for further unauthorized access or attacks.

Exploiting LFI vulnerabilities can have severe consequences, including unauthorized server access and sensitive data exposure. Attackers can leverage LFI to read system files, extracting sensitive information such as user credentials or configuration details. This vulnerability may facilitate further attacks, including remote code execution, if exploit techniques are advanced. Unauthorized exposure to system files could lead to data breaches, legal liabilities, and reputational damage for affected organizations. Moreover, exploiting LFI could result in service disruptions affecting business continuity. The broad accessibility of the vulnerable endpoint makes exploitation feasible, especially if combined with other attack vectors.
