How to Fix CVE-2025-1077: Critical Remote Code Execution Vulnerability in Visual Weather Systems?

IBL Software Engineering's Visual Weather product suite is a critical tool for weather forecasting and analysis. A recently discovered vulnerability, CVE-2025-1077, poses a significant threat to systems running Visual Weather and its derived products. This remote code execution (RCE) vulnerability could allow attackers to compromise affected servers, potentially leading to data breaches, service disruptions, and complete system control. This article provides a comprehensive overview of CVE-2025-1077, its impact, and detailed remediation strategies to help security professionals protect their environments.

A Short Introduction to Visual Weather Systems

Visual Weather, developed by IBL Software Engineering, is a comprehensive suite of software solutions used for meteorological data processing, visualization, and forecasting. It's used by a wide range of organizations, including weather service providers, aviation companies (Aero Weather), and satellite imagery analysis firms (Satellite Weather). Derived products like NAMIS are often customized for specific applications but share the same core codebase and, therefore, can be equally vulnerable. The software is designed to ingest, analyze, and display weather data from various sources, aiding in real-time decision-making.

Summary of CVE-2025-1077

CVE-2025-1077 arises from improper input validation within the Product Delivery Service (PDS) component. Specifically, the vulnerability is triggered when the PDS pipeline utilizes the IPDS pipeline with Message Editor Output Filters enabled. An unauthenticated attacker can exploit this flaw by sending specially crafted Form Properties within unauthenticated requests to the IPDS pipeline. This allows the attacker to remotely execute arbitrary Python code on the affected server. The complexity stems from the specific server configuration requirements, making exploitation slightly more challenging, but the potential for complete system compromise makes this a critical issue.

Impact of CVE-2025-1077

The impact of CVE-2025-1077 is severe. Successful exploitation can lead to remote code execution, potentially granting an attacker complete control over the affected Visual Weather server. This could enable them to access sensitive weather data, manipulate forecasts, disrupt critical services, and even use the compromised system as a launchpad for further attacks within the network.

If Visual Weather services are running under a privileged user account (which contradicts documented installation best practices), the attacker could gain full system-level privileges, further amplifying the damage. The vulnerability affects the confidentiality, integrity, and availability of both the vulnerable system and potentially subsequent systems, leading to a potential for significant financial and reputational damage. Given the critical role Visual Weather plays in many organizations, the disruption caused by a successful exploit could have far-reaching consequences. For more context, refer to the IBL advisory.
