CVE-2023-39024 Scanner

Harman Media Suite is a multimedia communication solution designed for enterprises to manage video content and facilitate virtual meetings. It is widely used in corporate settings, educational institutions, and by service providers to enhance communication and collaboration. The suite allows users to capture, stream, and archive media content, providing a centralized platform for media interactions. System administrators can configure user access and manage content channels through the Media Suite portal. Its primary users include IT departments, communication teams, and content managers aiming to streamline media processes. Harman Media Suite integrates with existing enterprise systems to offer a seamless experience for media management.

The Local File Disclosure vulnerability in Harman Media Suite allows unauthenticated access to downloadable files if anonymous access to the User Portal is enabled. This security flaw exists in versions up to and including 4.2.0, potentially exposing sensitive data stored within the application. Attackers could exploit this vulnerability to access confidential recordings and attachments without authentication. The risk is particularly high for organizations that have not restricted anonymous access settings. Such vulnerabilities highlight the importance of securing application endpoints and practicing robust access control measures. If exploited, it could lead to unauthorized data leaks compromising confidentiality.

Technically, the vulnerability is exploitable via HTTP requests to certain API endpoints within the Media Suite's User Portal. Attackers can craft requests to endpoints which fetch resources using immutable query parameters. Specific API endpoints, such as '/userportal/api/rest/contentChannels/' and related subpaths, are susceptible to being queried for sensitive data. The vulnerability response includes JSON that reveals information on channel content with parameters like 'channelId', 'callId', and more. This form of disclosure arises from improper handling of access tokens and insufficient restrictions on anonymous access to these endpoints. Such vulnerability is consistent with inadequate validation checks within the extent of the service API.

Exploitation of the Local File Disclosure vulnerability may lead to significant data leakage, impacting potentially sensitive information. Organizations could face exposure of corporate or private communications and media content files if unauthorized access is permitted. The disclosure could result in financial loss, reputational damage, or legal action due to exposure of confidential information. In certain scenarios, unauthorized data access can further facilitate more severe attacks by malicious actors leveraging disclosed data for further infiltration. Reducing such risks involves timely patching and enforcing strict access policies to safeguard sensitive application endpoints.
