The Arbitrary File Read vulnerability is a critical security flaw that enables unauthorized users to gain access to files that were not intended to be accessible. Specifically, in the context of the UFIDA NC, this vulnerability manifests itself within the nc.uap.lfw.file.action.DocServlet component of the software. Attackers can exploit this vulnerability by crafting specific requests that trick the system into divulging sensitive files stored on the server. It can lead to unauthorized data access, potentially exposing personal, financial, or proprietary business data. This vulnerability represents a significant risk, particularly for organizations handling sensitive data and requires immediate attention and rectification.

The vulnerability centers around an improper handling parameter within the DocServlet endpoint, which has been identified to process incoming requests inadequately. Specifically, this component fails to correctly validate and sanitize requests, making it susceptible to manipulation by malicious actors. The crafted requests exploit the pageId and disp parameters, effectively bypassing standard access controls and allowing the reading of arbitrary files from the server's file system. The delivered payload takes advantage of these endpoint weaknesses to access restricted directories, such as viewing web.xml, revealing potentially critical information about the underlying system architecture.

The successful exploitation of this vulnerability can allow attackers to access confidential and potentially sensitive information stored on the organization's server. This breach can lead to privacy violations, intellectual property theft, and a compromise of customer and company data integrity. Additionally, an attacker possessing internal configurations and sensitive information may further exploit other vulnerabilities, leading to broader network or system compromises. Organizations may face reputational damage, legal repercussions, and potential financial losses as a consequence of the data exposure and violation of compliance regulations.
