What the vulnerability is
Retrospective reports indicate that SolarView Compact contains a command injection vulnerability identified as CVE-2022-29303. The flaw stems from improper validation of input values within the “send test mail” console of the product’s web server (CWE-78). This type of vulnerability typically occurs when an application passes unsafe user-supplied data to a system shell, potentially allowing an attacker to execute arbitrary operating system commands.
Exposure and applicability
This vulnerability specifically affects the SolarView Compact product. In an industrial context, these systems are utilized for monitoring and managing solar power infrastructure. Asset owners and OT security leaders managing solar energy installations should determine if this specific hardware is deployed within their environment and whether the web-based management interface is accessible to untrusted networks.
Remediation priorities
Based on the reported vulnerability, our analysis suggests the following prioritized actions for OT operators:
- Update Firmware: The primary remediation is to apply updates according to the vendor’s instructions. This addresses the root cause by implementing proper input validation.
- Evaluate Product Viability: In cases where the vendor has not provided an update or the hardware is end-of-life, operators should consider discontinuing use of the product to eliminate the risk.
- Network Segmentation: As a compensating control to limit potential impact, ensure that the SolarView Compact web interface is not exposed to the public internet and is isolated from critical process control networks via a firewall or DMZ.
How to validate remediation
To verify that exposure has been reduced, operators should:
* Verify Versioning: Confirm through the device management interface that the firmware version matches the patched version specified in the vendor’s update documentation.
* Access Control Audit: Review firewall logs and network configurations to ensure that access to the web server is restricted to authorized engineering workstations only.
Note: We do not recommend active vulnerability scanning or attempting to trigger the command injection on production equipment, as this could impact system availability.
Limits and open questions
It remains unknown whether this vulnerability has been utilized in ransomware campaigns. Additionally, while CISA provided a remediation deadline for federal agencies in August 2023, this date was a regulatory requirement for those specific entities and not a universal technical deadline. The effectiveness of any update depends on the correct application of vendor-supplied patches; a version check alone does not guarantee that all configuration risks are mitigated.
