Security readout for executives and security teams
Plain-English summary
CVE-2022-35872 is a high-impact code execution flaw in Inductive Automation Ignition 8.1.15 build b2022030114. An attacker would need a user to visit malicious content or open a malicious file, but successful exploitation could run code as SYSTEM, creating serious operational risk.
Executive priority
Prioritize remediation for any affected Ignition deployment in operational or industrial environments. The attack requires user interaction, but SYSTEM-level code execution can affect availability and control-system integrity, so exposure should be confirmed promptly.
Technical view
The flaw is in ZIP file parsing and stems from deserialization of untrusted data, mapped to CWE-502. The CVSS 3.0 score is 7.8 with user interaction required and high confidentiality, integrity, and availability impact. The only affected version named in the bundle is Ignition 8.1.15 b2022030114.
Likely exposure
Exposure appears limited to environments running Inductive Automation Ignition 8.1.15 build b2022030114, especially systems where users import, open, or otherwise process ZIP-based content. The source bundle does not provide a broader affected-version range or CPE data.
Exploitation context
The sources describe required user interaction: the target must visit a malicious page or open a malicious file. KEV is false in the bundle, and no provided source states active exploitation in the wild.
Researcher notes
Evidence is specific but narrow. The bundle identifies ZIP parsing and unsafe deserialization in one Ignition build, with ZDI reference ZDI-22-1019 and CVE metadata. It does not include detailed patch version data, exploit status, or a complete affected-version matrix.
Mitigation direction
- Inventory Ignition installations and identify any 8.1.15 b2022030114 systems.
- Check Inductive Automation guidance for fixed versions or supported remediation.
- Restrict handling of untrusted ZIP files on Ignition systems and administrator workstations.
- Limit browsing and email attachment access from systems managing Ignition.
- Review service privilege configuration against vendor-supported hardening guidance.
Validation and detection
- Confirm installed Ignition version and build number on all relevant hosts.
- Review logs for unexpected file imports or suspicious ZIP handling activity.
- Verify whether affected systems process files from external or untrusted sources.
- Confirm vendor remediation status against Inductive Automation advisory guidance.
- Check endpoint controls for alerts around SYSTEM-context child processes.

Deserialization of Untrusted Data
Deserialization of Untrusted Data represents a recurring weakness pattern that can create exploitable paths when design, validation, or implementation controls are missing.
