Synthesised by an AI model from the NVD description and linked references — a reading aid, not an authoritative source.
This vulnerability is an authentication bypass flaw in Inductive Automation Ignition version 8.1.15 (build b2022030114). It resides in the com.inductiveautomation.ignition.gateway.web.pages component and stems from missing authentication checks before granting access to functionality, as tracked under CWE-288. The issue carries a CVSS 3.1 score of 9.8 and was originally reported as ZDI-CAN-17211.
Remote attackers can exploit the flaw without any credentials or user interaction to bypass authentication entirely on affected installations. Successful exploitation grants attackers full control over the system, resulting in high impact to confidentiality, integrity, and availability.
Advisories from the Zero Day Initiative and Inductive Automation address the issue in the context of Pwn2Own 2022 findings, with mitigation details and updates referenced at the vendor support portal and ZDI-22-1016.
The EPSS score rose materially from a low baseline to a peak of 0.1434 on 2025-01-22 before receding to 0.0256, indicating that exploitation interest emerged well after the 2022 disclosure and that the CVE merits renewed attention.

Control response
Mitigating Controls (NIST 800-53 r5) AI
Directly enforces approved authorizations (including authentication) before granting access to functionality in components such as com.inductiveautomation.ignition.gateway.web.pages.
Requires users to be identified and authenticated prior to accessing system functions, directly blocking the unauthenticated remote access path exploited by CVE-2022-35869.
Mandates authorization and configuration controls for all remote connections to the Ignition gateway, limiting the unauthenticated remote exploitation vector.
Mitigating Controls (NIST CSF 2.0) AI
Derived directly from the weakness types (CWEs) cited in the NVD entry via our AI-authored CWE→CSF cross-walk (authority under review) — links open the control.
Requiring authentication on every channel and path directly eliminates alternate-path bypasses.
Enforcing authorizations and least privilege across all access vectors prevents unauthenticated alternate paths.
Protecting networks and environments from unauthorized logical access blocks bypass via undocumented channels.
Mitigating Controls (ISO/IEC 27001:2022 Annex A) AI
Derived directly from the weakness types (CWEs) cited in the NVD entry via our AI-authored CWE→ISO cross-walk (authority under review) — links open the control.
Security testing can detect alternate-path bypasses but does not prevent them in production.
Secure authentication control directly mitigates bypass by requiring strong, consistent authentication on all paths.
Access control policy directly addresses alternate authentication paths by requiring all channels to enforce authentication.
Authentication information management ensures credentials and mechanisms are consistently applied across all access paths.
Access rights provisioning and review prevent bypass via unmonitored or alternate channels.
Privileged access rights control reduces risk of bypass through elevated or alternate paths.
