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 ASCO 5310 Single-Channel Remote Annunciator 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 2 structured product or package states remain unresolved. Apply remediation only to the exact product branch confirmed by its source.

- Summary
- CWE-319: Cleartext Transmission of Sensitive Information vulnerability exists that could result in the exposure of data when network traffic is being sniffed by an attacker.
- Remediation
- Schneider Electric is establishing a remediation plan for all future versions of ASCO 5310 Single-Channel Remote Annunciator and ASCO 5350 Eight Channel Remote Annunciator that may include a fix for these vulnerabilities. We will update this document when the remediation is available. Until then, customers should immediately apply the following mitigations to reduce the risk of exploit: • Use remote annunciator devices only in a protected environment to minimize network exposure and ensure that they are not accessible from public internet or untrusted networks. • Change default password to help prevent unauthorized access to device settings and information. • Setup network segmentation and implement a firewall to block all unauthorized access to the annunciator port 80/HTTP. • For more details on the ASCO 5310 refer to “Installation Manual | ASCO 5310 ATS Remote Annunciator” which can be found here: https://www.se.com/ww/en/product-range/66129-asco-5310-singlechannelremote-annunciator/-documents • For more details on the ASCO 5350 refer to “Installation Manual | ASCO 5350 ATS Remote Annunciator” which can be found here: https://www.se.com/ww/en/product-range/66130-asco-5350-eight-channelremote-annunciator/-documents To ensure you are informed of all updates, including details on affected products and remediation plans, subscribe to Schneider Electric’s security notification service here: https://www.se.com/en/work/support/cybersecurity/security-notifications.jsp

Fix availability varies by product01
What, why and how
CWE-319: Cleartext Transmission of Sensitive Information vulnerability exists that could result in the exposure of data when network traffic is being sniffed by an attacker.
What
CWE-319: Cleartext Transmission of Sensitive Information vulnerability exists that could result in the exposure of data when network traffic is being sniffed by an attacker.
Why
The product transmits sensitive or security-critical data in cleartext in a communication channel that can be sniffed by unauthorized actors.
How
An attacker operating through a network path may attempt exploitation without authentication or user interaction. If successful, the issue may obtain information outside the intended access boundary.

02
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 → Cleartext Transmission of Sensitive Information → obtain information outside the intended access boundary
- Attack surface
- Network
- Privileges required
- None: unauthenticated exploitation is possible
- User interaction
- None
- Attack complexity
- Low: no specialised conditions are recorded

CWE means Common Weakness Enumeration: a standard category for the underlying weakness. - CWE-319 ↗
CWE-319: Cleartext Transmission of Sensitive Information. The product transmits sensitive or security-critical data in cleartext in a communication channel that can be sniffed by unauthorized actors.

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
- Affected
- 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
- Schneider Electric is establishing a remediation plan for all future versions of ASCO 5310 Single-Channel Remote Annunciator and ASCO 5350 Eight Channel Remote Annunciator that may include a fix for these vulnerabilities.
