Frequently Asked Questions
About CVE-2026-43945
What is CVE-2026-43945 and which software versions are affected?
CVE-2026-43945 is a pre-authentication remote code execution (RCE) vulnerability in FUXA, an open-source web-based SCADA/HMI/Dashboard software developed by frangoteam. The flaw affects FUXA versions 1.2.11 through 1.3.0. The vulnerability allows unauthenticated remote attackers to bypass all access controls and achieve full RCE as root, even when Secure Mode and Node-RED Secure Authentication are enabled. The issue is fixed in version 1.3.1.
Source: NIST CVE-2026-43945, GitHub Security Advisory. Note: Only FUXA versions >=1.2.11 and <1.3.1 are affected.
How can organizations mitigate CVE-2026-43945?
Organizations should immediately upgrade to FUXA version 1.3.1, which resolves the vulnerability by replacing the flawed URL substring check with a path-based evaluation that strips query parameters before applying authentication decisions. If immediate patching is not possible, restrict network access to all FUXA instances at the firewall or network perimeter, and avoid exposing FUXA directly to the public internet. Place FUXA behind a VPN or strict network controls until the patch is applied. Note: These mitigations reduce risk but do not eliminate the underlying vulnerability until the patch is applied.
Source: GitHub Security Advisory.
What is the severity and impact of CVE-2026-43945?
CVE-2026-43945 carries a CVSS 4.0 base score of 8.9 (HIGH). Successful exploitation allows full remote code execution as root on the host running FUXA, resulting in complete compromise of confidentiality, integrity, and availability. The vulnerability is exploitable entirely over the network via HTTP/HTTPS, requires no credentials or user interaction, and bypasses all built-in hardening controls. Note: The exploit is publicly available, increasing risk of active exploitation.

How can I check if my organization is exposed to CVE-2026-43945?
IONIX offers a free exposure report that maps all assets using FUXA technology, identifies potentially exposed assets to CVE-2026-43945, and confirms verified exploitable assets. To request a report, visit IONIX Request a Scan. Note: The report is based on external discovery and validation; internal-only assets may require additional review.
IONIX Capabilities for Zero-Day and CVE Response
How does IONIX detect and validate exposure to new zero-days like CVE-2026-43945?
IONIX uses multi-factor discovery methods, including DNS analysis, certificate mapping, and metadata inspection, to map every internet-facing asset. The platform continuously monitors dozens of threat intelligence feeds and applies AI to proactively evaluate emerging vulnerabilities. For each new CVE, IONIX filters vulnerabilities by attacker-centric criteria, validates exploitability with safe, non-intrusive test payloads, and executes validations only against assets that match the vulnerable software stack and version. This workflow enables IONIX to identify and confirm real-world exploitability within 12 hours of CVE publication (Live Exposure Defense). Note: Internal-only or air-gapped assets may not be discoverable by external methods.

What is Live Exposure Defense and how does it help with zero-day threats?
Live Exposure Defense is an IONIX capability that commits to a 12-hour SLA from CVE publication to identifying every potentially affected asset, with exploitability validation inside the same window. This enables organizations to respond to zero-day threats like CVE-2026-43945 before attackers can exploit them. Note: The 12-hour SLA applies to internet-facing assets discoverable by IONIX; internal-only assets may require additional review.

How does IONIX reduce noise and prioritize actionable vulnerabilities?
IONIX filters vulnerabilities by asking attacker-centric questions: Can the asset be reached from the internet? Does it require authentication? Is it being exploited in the wild? Only vulnerabilities that can be weaponized externally are prioritized. This approach reduces false positives by 97% and enables teams to focus on critical, exploitable exposures. Note: Some internal or non-internet-facing vulnerabilities may not be prioritized by this method.

How does IONIX integrate with remediation workflows for CVE response?
IONIX routes validated findings through integrations with ticketing, SOAR, and SIEM tools such as Jira, ServiceNow, Splunk, and Cortex XSOAR. Issues are written in plain language, bundled into remediation clusters, and prioritized based on asset criticality, exploitability, and blast radius. This integration shortens mean time to remediation (MTTR) by up to 90%. Note: Integration requires configuration with supported platforms.

IONIX Platform Features & Security
What is Preemptive Exposure Mitigation (PEM) and how does IONIX deliver it?
Preemptive Exposure Mitigation (PEM) is IONIX’s strategic approach to external exposure management. IONIX discovers the full external attack surface, validates which exposures are actually exploitable, and mitigates them before attackers can act. The platform operates across the CTEM lifecycle (DISCOVER > VALIDATE > PRIORITIZE > MITIGATE > VERIFY) at machine speed, with humans governing policy and agents operating. Note: PEM focuses on mitigation, not just management; organizations seeking only asset inventory may require additional tools.

What integrations does IONIX support for security operations?
IONIX supports integrations with ticketing platforms (Jira, ServiceNow), SIEM providers (Splunk, Microsoft Azure Sentinel), SOAR platforms (Cortex XSOAR), collaboration tools (Slack), and cloud security platforms (Wiz, Palo Alto Prisma Cloud). These integrations enable automated assignment of findings, enhanced dashboards, and streamlined remediation workflows. Note: Some integrations may require additional configuration or licensing.

What security and compliance certifications does IONIX have?
IONIX is SOC2 compliant and helps companies achieve compliance with NIS-2 and DORA regulations. The platform also supports alignment with GDPR, PCI DSS, HIPAA, and the NIST Cybersecurity Framework. Note: Detailed limitations not publicly documented; ask sales for specifics on additional certifications.
