CVE-2026-19472 – Denial of Service via Crafted HTTP PUT – Rockwell Automation ArmorStart LT (≤ v2.00

Be the first to know when new zero-days emerge:

Summary

CVE-2026-19472 is a denial-of-service vulnerability affecting Rockwell Automation ArmorStart® LT smart motor controllers (catalog numbers Bul 290E, 291E, and 294E). The flaw stems from improper handling of a crafted HTTP PUT request sent to the device’s embedded web server, allowing an unauthenticated network attacker to disrupt availability. The vulnerability carries a CVSS v4.0 base score of 8.7 (High) and a CVSS v3.1 score of 7.5.

Technical details

  • Root cause: The embedded web server on ArmorStart LT improperly handles a specially crafted HTTP PUT request, consistent with CWE-770 (Allocation of Resources Without Limits or Throttling).
  • Trigger conditions: An attacker sends a malformed/crafted HTTP PUT request to the device’s embedded web management interface over the network.
  • Attack vector: Network-based; the CVSS v4.0 vector (CVSS:4.0/AV:N/AC:L/AT:N/PR:N/UI:N/VC:N/VI:N/VA:H/SC:N/SI:N/SA:N) indicates low attack complexity, no privileges required, and no user interaction needed.
  • Impact: Successful exploitation results in loss of availability of the affected device — the web server and/or device functionality can become unresponsive, disrupting monitoring and control operations. No confidentiality or integrity impact is indicated.
  • Discovery: Identified internally by Rockwell Automation; there are no known public reports of active exploitation of this CVE.

Affected software

  • Rockwell Automation ArmorStart® LT (catalog numbers Bul 290E, 291E, and 294E) — firmware versions v2.001 and below

Severity

  • CVSS v3.1 Base Score: 7.5 (High)
  • CVSS v4.0 Base Score: 8.7 (High)
  • CVSS v4.0 Vector: CVSS:4.0/AV:N/AC:L/AT:N/PR:N/UI:N/VC:N/VI:N/VA:H/SC:N/SI:N/SA:N
  • CWE-770: Allocation of Resources Without Limits or Throttling

Mitigation and recommended actions

  • Immediate: Upgrade affected ArmorStart LT devices to firmware v2.002 or later, available via the Rockwell Automation downloads portal.
  • If patching is not immediately possible:
    • Restrict network access to the device’s embedded web server to trusted management networks only, using firewalls or network segmentation.
    • Avoid exposing ArmorStart LT web interfaces directly to the internet or untrusted networks.
    • Apply Rockwell Automation’s general industrial control system security best practices, including network segmentation, use of VPNs for remote access, and monitoring for anomalous HTTP traffic to device management interfaces.

How IONIX’s External Exposure Management Platform Detects and Validates
Zero-Days to Shrink MTTR

1

Map your entire attack surface (continously)

IONIX uses multi-factor discovery methods, including DNS analysis, certificate mapping, metadata inspection, and more, to automatically map every internet-facing asset across your environment. This includes cloud instances, third-party platforms, shadow IT, and even forgotten infrastructure that traditional tools miss.

2

Monitor for new CVEs

Dozens of threat intel feeds using agentic technology are continuously analyzed to detect the appearance of proof-of-concept code, exploit kits, and indicators of active targeting. IONIX goes further by applying AI to proactively evaluate whether emerging vulnerabilities are likely to be exploited, even before PoCs go public.

3

Identify Potential External Exposures

Not all CVEs matter. IONIX filters vulnerabilities by asking attacker-centric questions: Can it be reached from the internet? Does it require authentication? Is it being exploited in the wild? This dramatically reduces noise and focuses teams on threats that can actually be weaponized.

4

Create Safe, Scalable Exploit Validations

IONIX transforms real-world PoCs into safe, non-intrusive test payloads that can be run in production environments without disruption. These simulations are precisely targeted to the systems that are vulnerable, ensuring rapid validation without unnecessary load.

5

Execute Exploit Validations

By combining context about software stack, versioning, exposure status, and reachability, IONIX ensures that only the right payloads are executed against the right assets, maximizing efficiency and minimizing risk.

6

Drive Fast and Actionable Remediation

Results are routed through integrations with ticketing, SOAR, and SIEM tools. Issues are written in plain language, bundled into remediation clusters, and prioritized based on asset criticality, exploitability, and blast radius. This shortens mean time to remediation (MTTR) and empowers teams to act with confidence.
