Evidence used

  • No CISA KEV confirmation is currently recorded.
  • Exploitation requires an existing local or physical foothold with privileges.
  • EPSS is 0.12% for the current model date.

Compensating controls

  • Validate the affected product branch and deploy the verified fixed release.
  • Restrict local access and enforce least privilege on affected hosts.
  • Monitor vendor guidance and exploitation sources for a material change.

Verification

  1. Confirm that the asset runs Rockwell Automation ControlFLASH ® and falls inside the recorded affected range.
  2. Verify the installed build against the product-specific fixed version after deployment.
  3. Validate exposure, authentication requirements and compensating controls in the actual environment.
  4. Reopen this reassessment when CVSS, KEV, EPSS, exploit evidence or remediation changes.
Mitigation target: As exposure requiresRemediation target: Within 365 days

This automated reassessment organises public evidence. It does not know asset exposure, business impact or control effectiveness and does not replace CVSS or a human risk decision.

ENISA EUVD identifier

EUVD-2026-69136

No EUVD known-exploited evidence

A security issue exists within ControlFLASH™, where the installer grants write permissions to the "Everyone" group on a product installation directory. This could allow arbitrary code execution, resulting in an attacker being given the ability to run any commands or code of the attacker's choice on a target machine at the logged-in user's permission level.

What, why and how

A security issue exists within ControlFLASH™, where the installer grants write permissions to the "Everyone" group on a product installation directory. This could allow arbitrary code execution, resulting in an attacker being given the ability to run any commands or code of the attacker's choice on a target machine at the logged-in user's permission level.

What

A security issue exists within ControlFLASH™, where the installer grants write permissions to the "Everyone" group on a product installation directory. This could allow arbitrary code execution, resulting in an attacker being given the ability to run any commands or code of the attacker's choice on a target machine at the logged-in user's permission level.

Why

A security-sensitive function is reachable without the authentication check that should protect it.

How

An attacker operating through local access may attempt exploitation with low privileges. If successful, the issue may execute code or commands in the affected security context.

Exploit reality and attack path

CVSS severity, EPSS forecast probability, public exploit material and CISA-confirmed exploitation are separate signals.

Observed exploitation
?Confirmed exploitation and public exploit material are separate signals. Attacks can occur without public proof-of-concept or exploit code.
No confirmed evidence

No CISA KEV match was present at the last successful refresh. This means no confirmation from that source, not proof of no exploitation.

Public PoC / exploit material
?Confirmed exploitation and public exploit material are separate signals. Attacks can occur without public proof-of-concept or exploit code.
None recorded

No exploit-tagged reference or CISA SSVC proof-of-concept state is currently recorded. Research may still exist outside the structured feeds.

Likely attack path
local access → Missing Authentication for Critical Function → execute code or commands in the affected security context

Privileges required
Low: a basic authenticated account is required

Weakness
?CWE means Common Weakness Enumeration: a standard category for the underlying weakness.
CWE-306 ↗

CWE-306: Missing Authentication for Critical Function. The product does not perform any authentication for functionality that requires a provable user identity or consumes a significant amount of resources.

CVSS vector
?CVSS means Common Vulnerability Scoring System. The vector records the metric values used to calculate technical severity.

Common Vulnerability Scoring System 4.0: the compact vector below is decoded into plain language.

Post-exploitation / living off the land
After compromise, an attacker may use built-in shells, scripting engines, scheduled tasks and native network utilities for discovery, persistence or movement. This is a plausible LoTL path, not evidence that it has occurred for every attack.
