Patch only the product branches with a verified fix
Fix availability varies by productMedium technical severity with no CISA KEV confirmation; remediate through the normal risk-based patch cycle unless local exposure raises the priority. Verified remediation exists for at least one product or source, but 1 structured product or package state remain unresolved. Apply remediation only to the exact product branch confirmed by its source.

Compensating controls
- Apply the linked authoritative mitigation while planning the permanent fix.
- Restrict the affected network interface to trusted sources where business-safe.
- Monitor vendor guidance and exploitation sources for a material change.
Verification
- Confirm that the asset runs Schneider Electric Conext™ ComBox and falls inside the recorded affected range.
- Recheck the vendor advisory before scheduling a change because no verified fixed version is currently retained.
- Validate exposure, authentication requirements and compensating controls in the actual environment.
- Reopen this reassessment when CVSS, KEV, EPSS, exploit evidence or remediation changes.
Remediation availability differs by product scope
Verified remediation exists for at least one product or source, but 1 structured product or package state remain unresolved. Apply remediation only to the exact product branch confirmed by its source.

- Summary
- A CWE-1021: Improper Restriction of Rendered UI Layers or Frames vulnerability exists that could cause an adversary to trick the interface user/admin into interacting with the application in an unintended way when the product does not implement restrictions on the ability to render within frames on external addresses
- Remediation
- Conext™ ComBox product was discontinued as of January 2020 and is no longer in support. Customers should immediately apply the following mitigations to reduce the risk of exploit: Do not expose the Conext™ Combox directly to the Internet Do not grant network access to unknown computers Computer(s) must be kept up to date with the latest security patches Customers should also consider upgrading to the latest product offering InsightHome & InsightFacility to resolve these issues.

Fix availability varies by product01
What, why and how
A CWE-1021: Improper Restriction of Rendered UI Layers or Frames vulnerability exists that could cause an adversary to trick the interface user/admin into interacting with the application in an unintended way when the product does not implement restrictions on the ability to render within frames on external addresses. Affected Products: Conext™ ComBox (All Versions)
What
A CWE-1021: Improper Restriction of Rendered UI Layers or Frames vulnerability exists that could cause an adversary to trick the interface user/admin into interacting with the application in an unintended way when the product does not implement restrictions on the ability to render within frames on external addresses. Affected Products: Conext™ ComBox (All Versions)
Why
The web application does not restrict or incorrectly restricts frame objects or UI layers that belong to another application or domain.
How
An attacker operating through a network path may attempt exploitation without authentication after a user interaction. If successful, the issue may cause the confidentiality, integrity or availability impact described by the vendor.

Exploit reality and attack path
CVSS severity, EPSS forecast probability, public exploit material and CISA-confirmed exploitation are separate signals.
Observed exploitation No confirmed evidence
?
Confirmed exploitation and public exploit material are separate signals. Attacks can occur without public proof-of-concept or exploit code.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 None recorded
?
Confirmed exploitation and public exploit material are separate signals. Attacks can occur without public proof-of-concept or exploit code.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
- a network path → Improper Restriction of Rendered UI Layers or Frames → cause the confidentiality, integrity or availability impact described by the vendor
- Attack surface
- Network
- Privileges required
- None: unauthenticated exploitation is possible
- User interaction
- Required interaction required
- Attack complexity
- Low: no specialised conditions are recorded
- Security boundary
- Unchanged: impact remains within the vulnerable component's security authority
- Weakness
?
CWE means Common Weakness Enumeration: a standard category for the underlying weakness. - CWE-1021 ↗
CWE-1021: Improper Restriction of Rendered UI Layers or Frames. The web application does not restrict or incorrectly restricts frame objects or UI layers that belong to another application or domain.
- CVSS vector
?
CVSS means Common Vulnerability Scoring System. The vector records the metric values used to calculate technical severity. CVSS:3.1/AV:N/AC:L/PR:N/UI:R/S:U/C:N/I:H/A:NCommon Vulnerability Scoring System 3.1: the compact vector below is decoded into plain language.
AVNetworkAttack vector: The vulnerable component can be reached over a network.ACLowAttack complexity: No specialised conditions are required beyond attacker-controlled input.PRNonePrivileges required: The attacker does not need an account or existing privileges.UIRequiredUser interaction: Another user must perform an action for exploitation to succeed.SUnchangedScope: The security impact remains within the vulnerable component's authority.CNoneConfidentiality impact: No direct loss is represented by this metric.IHighIntegrity impact: A successful attack can cause a major loss.ANoneAvailability impact: No direct loss is represented by this metric.- Post-exploitation / living off the land
- No specific living-off-the-land technique is confirmed in the structured sources. Monitor normal administration tools for activity inconsistent with the affected service's baseline.
03
Patch and workaround
Operational remediation based on structured source evidence.
- Status
?
Patch availability is based on structured fixed-version fields and authoritative update references. If no fix is verified, check the vendor advisory before making a change. - Fix availability varies by product
- Action
- Use the product-specific evidence above. Patch only products with a verified fixed release, and keep every affected or under-investigation state without a matching fix in the remediation queue.
- Workaround
- Conext™ ComBox product was discontinued as of January 2020 and is no longer in support. Customers should immediately apply the following mitigations to reduce the risk of exploit: Do not expose the Conext™ Combox directly to the Internet Do not grant network access to unknown computers Computer(s) must be kept up to date with the latest security patches Customers should also consider upgrading to the latest product offering InsightHome & InsightFacility to resolve these issues.
