CVE-2025-1077 Overview
A critical remote code execution vulnerability has been identified in IBL Software Engineering Visual Weather and its derived products, including NAMIS, Aero Weather, and Satellite Weather. The vulnerability exists in the Product Delivery Service (PDS) component when specific server configurations utilize the IPDS pipeline with Message Editor Output Filters enabled.
A remote unauthenticated attacker can exploit this vulnerability to send unauthenticated requests to execute the IPDS pipeline with specially crafted Form Properties, enabling remote execution of arbitrary Python code. This vulnerability could lead to a full system compromise of the affected server, particularly if Visual Weather services are run under a privileged user account—contrary to the documented installation best practices.
Critical Impact
Unauthenticated remote attackers can achieve full system compromise through arbitrary Python code execution on affected Visual Weather servers.
Affected Products
- IBL Software Engineering Visual Weather (versions prior to 7.3.10 and 8.6.0)
- NAMIS (derived product)
- Aero Weather (derived product)
- Satellite Weather (derived product)

Technical Details for CVE-2025-1077
Vulnerability Analysis
This vulnerability represents a critical improper input validation flaw (CWE-20) in the Product Delivery Service (PDS) component of Visual Weather and its derived products. The core issue arises from insufficient validation of user-supplied input in the IPDS pipeline when Message Editor Output Filters are enabled.
The attack surface is exposed through network-accessible services that accept unauthenticated requests. When an attacker submits specially crafted Form Properties to the PDS endpoint, the application fails to properly sanitize or validate these inputs before passing them to the Python interpreter for execution. This allows arbitrary Python code to be injected and executed within the server's context.
The impact is significantly amplified in environments where Visual Weather services are configured to run under privileged user accounts, potentially granting attackers elevated system access beyond the application scope.
Root Cause
The root cause of CVE-2025-1077 is improper input validation (CWE-20) in the IPDS pipeline component. The Product Delivery Service fails to adequately validate and sanitize Form Properties before processing them through the Message Editor Output Filters. This allows attackers to inject malicious Python code that gets executed by the server without proper authorization checks or input sanitization.
Attack Vector
The attack leverages the network-accessible Product Delivery Service endpoint. An unauthenticated attacker can craft malicious HTTP requests containing specially formatted Form Properties designed to escape the intended processing context and inject arbitrary Python code.
The exploitation requires:
- Network access to the PDS service endpoint
- Server configuration with IPDS pipeline enabled
- Message Editor Output Filters feature enabled
The vulnerability does not require authentication, user interaction, or prior access to the system. Successful exploitation results in arbitrary code execution with the privileges of the Visual Weather service account.
Detection Methods for CVE-2025-1077
Indicators of Compromise
- Unexpected or malformed requests to the Product Delivery Service (PDS) endpoints
- Anomalous Python process spawning from Visual Weather service processes
- Unusual network connections originating from the Visual Weather server
- Log entries showing Form Properties with Python code syntax or escape sequences
Detection Strategies
- Monitor HTTP request logs for unusual Form Properties payloads containing Python syntax patterns such as import, exec, eval, or subprocess
- Implement network intrusion detection rules to identify exploitation attempts targeting the PDS endpoint
- Review Visual Weather application logs for processing errors or exceptions indicating malformed input
- Deploy endpoint detection solutions to monitor for unauthorized child processes spawned by Visual Weather services
Monitoring Recommendations
- Enable verbose logging for the Product Delivery Service component
- Implement real-time alerting for requests to IPDS pipeline endpoints from untrusted sources
- Monitor process creation events on Visual Weather servers for anomalous Python execution
- Establish baseline network behavior and alert on deviations from normal traffic patterns
How to Mitigate CVE-2025-1077
Immediate Actions Required
- Upgrade Visual Weather to version 7.3.10 or higher, or version 8.6.0 or higher immediately
- Ensure Visual Weather services are NOT running under privileged user accounts, following documented installation best practices
- Restrict network access to the Product Delivery Service endpoint using firewall rules
- Audit server configurations to identify deployments using IPDS pipeline with Message Editor Output Filters enabled
Patch Information
IBL Software Engineering has released patched versions that address this vulnerability. Organizations should upgrade to version 7.3.10 or higher for the 7.x branch, or version 8.6.0 or higher for the 8.x branch. Refer to the IBLSoft Security Advisory for detailed upgrade instructions and release notes.
Workarounds
- Disable the Message Editor Output Filters feature if not required for operations
- Implement network segmentation to isolate Visual Weather servers from untrusted networks
- Deploy a web application firewall (WAF) to filter malicious requests targeting the PDS endpoint
- Run Visual Weather services under a dedicated, least-privilege service account to limit the impact of potential compromise
