Official description Straight from the sourceThe vendor's or NVD's own wording, published unedited. Authoritative, but often terse — it says what broke, rarely what to do.

NVD · unedited
The Western Digital My Cloud Web App [https://os5.mycloud.com/] uses a weak SSLContext when attempting to configure port forwarding rules. This was enabled to maintain compatibility with old or outdated home routers. By using an "SSL" context instead of "TLS" or specifying stronger validation, deprecated or insecure protocols are permitted. As a result, a local user with no privileges can exploit this vulnerability and jeopardize the integrity, confidentiality and authenticity of information transmitted. The scope of impact cannot extend to other components and no user input is required to exploit this vulnerability.

Technical summary Written by usOur analysis, written from the advisory, the CVSS vector and the affected-version data. It adds context the advisory leaves out, and never invents facts that are not in the source.

dbcve analysis · moderate confidence

The Western Digital My Cloud Web App uses a weak SSLContext configured with 'SSL' instead of 'TLS' when handling port forwarding rule configurations. This permits deprecated and insecure protocols (SSLv3, TLS 1.0, TLS 1.1) and weaker cipher suites, allowing a local unprivileged attacker to intercept, modify, or impersonate transmitted data due to reduced cryptographic protections.

MitigationReplace the weak SSLContext configuration with TLS 1.2+ and proper certificate validation, removing backward compatibility with legacy protocols while maintaining router compatibility through alternative means.

Am I affected? How to checkSteps we derive from the advisory and the affected-version data, so you can decide whether this CVE reaches your setup. They are a guide, not a scan — your own configuration is the authority.

dbcve checks

Work through these to decide whether this CVE applies to you.

  1. Identify your My Cloud device model
    Locate the model number label on the device or access the device dashboard to confirm the exact model (e.g., Pr2100, Pr4100, Ex4100, Ex2 Ultra, Mirror G2, Dl2100, Dl4100, Ex2100)
    Affected if The device is one of the listed models and firmware version is below 5.23.114
  2. Check installed firmware version
    Log into the My Cloud web interface, navigate to Settings > About or System > Firmware, and record the displayed firmware version number
    Affected if The firmware version shown is less than 5.23.114 (for example, 5.23.113, 5.22.x, or earlier)
  3. Verify if port forwarding is configured
    Access the router or My Cloud interface Port Forwarding settings (usually under Network or Advanced settings) and check if any port forwarding rules are defined for the My Cloud device
    Affected if Port forwarding rules exist and the device firmware is below 5.23.114 - this is the specific feature where the weak SSLContext is used
  4. Confirm the device web interface is accessible
    Attempt to access the My Cloud dashboard via HTTPS (typically https://[device-ip] or via mycloud.com)
    Affected if The web interface is reachable and the firmware is vulnerable, meaning connections may use weak SSL/TLS protocols when port forwarding rules are processed

You are affected if you own a listed My Cloud model with firmware version below 5.23.114 and have port forwarding rules configured, as the web app uses weak SSL instead of TLS for handling those configurations.

Remediation Closing itWhat it takes to close this. Where a vendor fix exists we point at it; where none exists we say so plainly, and can build one. Effort estimates are scoped from the advisory, not from your codebase.

dbcve · scoped
Upgrade available Upgrade to 5.23.114 or later
Fixed in 5.23.114
Interim mitigation

Replace the weak SSLContext configuration with TLS 1.2+ and proper certificate validation, removing backward compatibility with legacy protocols while maintaining router compatibility through alternative means.

Recommended fix High confidence

Firmware version 5.23.114 or later for affected My Cloud models (Pr2100, Pr4100, Ex4100, Ex2 Ultra, Mirror G2, Dl2100, Dl4100, Ex2100)

  1. Log in to the My Cloud device admin interface (typically via web browser at the device IP address)
  2. Navigate to Settings > System or Settings > Firmware Update
  3. Check for firmware updates or locate the manual firmware update option
  4. Update firmware to version 5.23.114 or later (the fixed release)
  5. Wait for the firmware update to complete and the device to reboot
  6. Verify the firmware version has been updated successfully
Caveat Firmware updates may temporarily interrupt device availability; ensure proper backup of critical data before updating
