CVE-2025-13911 — Inductive Automation Ignition Execution with Unnecessary Privileges
Ignition by Inductive Automation, when installed with default OS service account settings, may expose the host system to an elevated code execution risk via the gateway backup restore functionality. An authenticated user with Gateway Administrator privileges can import a malicious gateway backup (.gwbk) file containing crafted project resources, scripts, or modules, resulting in code execution on the host system. This affects both Windows and Linux installations. On Windows, default installations often run the Ignition service as NT AUTHORITY\SYSTEM, resulting in code execution with full local system privileges. On Linux, default installations commonly run the Ignition service as root or with elevated privileges. Specific privilege level depends on installation configuration.
Who exploits it and how urgent it is
A 0–100 score combining confirmed exploitation, ransomware and APT use, public exploits, EPSS and severity.
How the score was calculated
- EPSS 0.3% (30-day exploitation probability)+2
- Technical severity (medium)+3
The score orders the patch queue; it does not replace your asset context (internet exposure, criticality, compensating controls).
Triage
Is it exploited, how likely is exploitation, what does it touch, and how severe do the sources call it.
CISA SSVC assessment CISA
Three decision points CISA publishes for the CVEs it assesses (SSVC 2.0.3). A stakeholder decision, not a severity score.
Remediation
Fixes and mitigations documented by the sources — linked to the original advisory.
No fix documented by the sources we poll. That does not mean none exists: check the vendor advisory.
First 24 hours
Ordered from the record’s own fields — exposure first, because you cannot patch what you have not found. A rule-generated starting point.
- Identify exposed assets running the affected vendor/product/version combinations (Inductive Automation Ignition).
- No fix documented in the sources: reduce exposure and monitor the vendor advisory.
- Search available logs for exploit probes matching the vulnerability class (privilege escalation), errors and authentication anomalies.

What should defenders know first?
CVE-2025-13911 is "Inductive Automation Ignition Execution with Unnecessary Privileges", rated Medium. It affects Ignition (Inductive Automation); versions are in the scope table. It is not in CISA KEV, which does not rule out exploitation. CVSS 6.4 describes technical severity. EPSS 0.25% estimates the probability of exploitation in 30 days; neither replaces your asset context. First verify whether exposed or business-critical assets run the affected versions, apply vendor fixes or mitigations, and preserve logs for review.
