CVE-2022-35890: An issue was discovered in Inductive Automation Ignition before 7.9.20 and 8.x before 8.1.17.

An issue was discovered in Inductive Automation Ignition before 7.9.20 and 8.x before 8.1.17. Designer and Vision Client Session IDs are mishandled. An attacker can determine which session IDs were generated in the past and then hijack sessions assigned to these IDs via Randy.

Security readout for executives and security teams

Plain-English summary

Ignition versions before 7.9.20 and 8.x before 8.1.17 mishandled Designer and Vision Client session IDs. The reported risk is session hijacking if an attacker can determine previously generated IDs. This matters because Ignition is often operational software, but the supplied sources do not provide CVSS scoring or confirmed active exploitation.

Executive priority

Prioritize remediation for internet-facing, third-party-accessible, or operationally critical Ignition systems. Treat this as high priority because the described impact is session hijacking, while noting that active exploitation is not confirmed in the provided sources.

Technical view

CVE-2022-35890 describes predictable or otherwise mishandled Designer and Vision Client session IDs in Inductive Automation Ignition. The CVE states attackers can identify session IDs generated in the past and hijack sessions assigned to them via Randy. The bundle does not include CWE, CVSS, authentication prerequisites, network position, or detailed fixed build notes beyond the affected version thresholds.

Likely exposure

Organizations running Inductive Automation Ignition before 7.9.20, or 8.x before 8.1.17, may be exposed. Exposure is most relevant where Designer or Vision Client sessions are reachable by untrusted users or networks.

Exploitation context

The CVE references public Randy material, indicating public research or tooling context exists. However, the source bundle does not show CISA KEV listing, confirmed exploitation in the wild, or reliable exploit prevalence.

Researcher notes

Evidence is limited to the CVE description and references. The bundle names affected version ranges and a public Randy reference, but lacks CVSS, CWE, exploit conditions, privileges required, and detailed remediation language. Avoid assuming broader Ignition components are affected without vendor confirmation.

Mitigation direction

  • Upgrade Ignition to 7.9.20, 8.1.17, or later supported releases.
  • Review Inductive Automation guidance for exact upgrade and compatibility requirements.
  • Restrict access to Ignition Designer and Vision Client interfaces.
  • Invalidate active sessions after upgrade or incident suspicion.
  • Monitor authentication and session activity for unusual reuse patterns.

Validation and detection

  • Inventory all Ignition instances and record exact versions.
  • Confirm no instance runs before 7.9.20 or 8.1.17.
  • Identify internet-facing or broadly reachable Designer and Vision Client paths.
  • Review logs for suspicious session reuse or unexpected client access.
  • Check vendor advisory for any additional product-specific validation.
