Frequently Asked Questions
About CVE-2026-61500 & Vulnerability Response
What is CVE-2026-61500 and which software versions are affected?
CVE-2026-61500 is a critical unauthenticated remote code execution (RCE) vulnerability in Rejetto HFS (HTTP File Server) versions 3.0.0 through 3.2.0. The vulnerability allows attackers to forge administrator session cookies and execute arbitrary code on the server without authentication, due to the use of a predictable session-cookie signing key derived from JavaScript's non-cryptographic Math.random() function. All releases in the 3.0.0–3.2.0 range are vulnerable. Note: Only Rejetto HFS versions 3.0.0–3.2.0 are affected; other versions are not impacted. [NIST NVD]
How can organizations mitigate CVE-2026-61500?
Organizations should immediately upgrade to Rejetto HFS version 3.2.1 or later, as this release resolves the vulnerability. If immediate patching is not feasible, restrict access to the HFS instance at the network perimeter, apply firewall or reverse-proxy rules to limit login endpoint access to trusted IP ranges, and monitor for anomalous or repeated unauthenticated login attempts in HFS access logs. Note: These mitigations reduce risk but do not fully eliminate the vulnerability until patching is complete. [Vendor Fix]
How does IONIX detect and validate exposures to zero-day vulnerabilities like CVE-2026-61500?
IONIX uses multi-factor discovery methods—including DNS analysis, certificate mapping, and metadata inspection—to continuously map every internet-facing asset, including cloud instances, third-party platforms, and shadow IT. For zero-day vulnerabilities, IONIX analyzes dozens of threat intelligence feeds and applies AI to proactively evaluate exploitability. The platform filters vulnerabilities by attacker-centric criteria (e.g., reachability, authentication requirements, active exploitation) and transforms real-world proof-of-concept code into safe, non-intrusive test payloads for validation. This ensures only confirmed exploitable exposures are prioritized for mitigation. Note: Validation is targeted and non-disruptive, but organizations with highly sensitive production environments should review validation settings. [IONIX Threat Center]
IONIX Platform Capabilities & Workflow
What is Preemptive Exposure Mitigation (PEM) and how does IONIX deliver it?
Preemptive Exposure Mitigation (PEM) is IONIX's approach to external exposure management. IONIX discovers the full external attack surface—including unknown assets, subsidiaries, and digital supply chain dependencies—validates which exposures are actually exploitable, and mitigates them before attackers can act. The workflow follows five steps: DISCOVER, VALIDATE, PRIORITIZE, MITIGATE, and VERIFY. IONIX operates at machine speed with agentic automation, while humans govern policy and priorities. Note: PEM focuses on mitigation, not just management; organizations seeking only asset inventory may require additional tools. [Why IONIX]
How does IONIX prioritize exposures for remediation?
IONIX prioritizes exposures based on asset criticality, exploitability, and blast radius. The platform bundles issues into remediation clusters and routes them through integrations with ticketing, SOAR, and SIEM tools. Only exposures validated as exploitable and reachable from the internet are escalated, reducing noise and focusing teams on actionable threats. Note: Prioritization is automated but can be customized to align with organizational risk tolerance. [Why IONIX]
What is Live Exposure Defense and what is the 12-hour SLA?
Live Exposure Defense is an IONIX capability that commits to identifying every potentially affected asset within 12 hours of a new CVE's publication. Exploitability validation runs inside the same window, ensuring organizations can respond to emerging threats before attackers exploit them. Note: The 12-hour SLA applies to supported asset types and may require integration with IONIX's discovery and validation workflows. [Why IONIX]
How does IONIX integrate with ticketing, SOAR, and SIEM platforms?
IONIX supports integrations with Jira, ServiceNow, Splunk, Microsoft Azure Sentinel, Cortex XSOAR, and Slack. Findings and remediation tasks are automatically assigned to the right teams, and incidents can be retrieved via REST API for enhanced dashboards, custom alerts, and streamlined workflows. Additional connectors are available based on customer requirements. Note: Integration depth may vary by platform; verify compatibility with your environment. [Cortex XSOAR Integration]
Does IONIX require agents or sensors to discover exposures?
No, IONIX does not require agents or sensors. Discovery starts from zero, mapping assets from the internet using external signals such as DNS, certificates, and metadata. This approach finds assets that are not in existing inventories and does not depend on endpoint or cloud agent deployment. Note: Organizations seeking internal asset inventory may require complementary tools. [Why IONIX]
Security, Compliance & Implementation
What security and compliance certifications does IONIX have?
IONIX is SOC2 compliant, meeting rigorous standards for security, availability, processing integrity, confidentiality, and privacy. The platform also supports compliance with NIS-2 and DORA regulations, and helps organizations align with frameworks such as GDPR, PCI DSS, HIPAA, and the NIST Cybersecurity Framework. Note: Detailed limitations not publicly documented; ask sales for specifics on additional certifications. [Regulatory Compliance]
How long does it take to implement IONIX and how easy is it to start?
IONIX is designed for rapid deployment, with initial setup typically taking about one week. The process requires minimal resources—often just one person to scan the entire network. Comprehensive onboarding resources, including step-by-step guides, tutorials, and webinars, are provided. Dedicated technical support is available throughout implementation. Note: Organizations with highly complex environments may require additional integration time. [Customer Review]
