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
A CWE-640: Weak Password Recovery Mechanism for Forgotten Password vulnerability exists in PowerLogic PM55xx, PowerLogic PM8ECC, PowerLogic EGX100 and PowerLogic EGX300 (see security notification for version infromation) that could allow an attacker administrator level access to a device.

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

CWE-640 vulnerability in PowerLogic PM55xx, PM8ECC, EGX100, and EGX300 devices allows attackers to exploit a weak password recovery mechanism for forgotten passwords, enabling unauthorized administrator-level access to the device.

MitigationApply vendor-supplied firmware updates addressing the weak password recovery mechanism; if unavailable, restrict network access to management interfaces and implement additional authentication controls.

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 the PowerLogic device model
    Access the device web interface or console and locate the device model identifier (PM5560, PM5561, PM5562, PM5563, PM8ECC, EGX100, or EGX300) in the device information or status page
    Affected if The device model is one of: PM5560, PM5561, PM5562, PM5563, PM8ECC, EGX100, or EGX300
  2. Check the installed firmware version
    Navigate to the device firmware or system information page in the web interface, or use the device console/CLI to retrieve the firmware version string
    Affected if The firmware version is below the fixed version for your model (PM5560/PM5563: 2.7.8, PM5561: 10.7.3, PM5562: 2.5.4, or PM8ECC: any version)
  3. Confirm network accessibility of password recovery interface
    Verify that the device management interface (HTTP/HTTPS web portal) is reachable from the network where password recovery would be attempted
    Affected if The device management interface is exposed to network segments where unauthorized users could reach it

You are affected if your device model is in the affected list and the installed firmware version falls below the fixed version (or is any version for PM8ECC), combined with network accessibility of the management interface.

Interim mitigation

Apply vendor-supplied firmware updates addressing the weak password recovery mechanism; if unavailable, restrict network access to management interfaces and implement additional authentication controls.

Recommended fix High confidence

Upgrade to firmware 2.7.8 (Pm5560/Pm5563), 10.7.3 (Pm5561), 2.5.5+ (Pm5562); contact Schneider for PM8ECC

  1. 1. Identify the specific PowerLogic device model (Pm5560, Pm5561, Pm5562, Pm5563, or PM8ECC) in your environment
  2. 2. Determine the current firmware version of the device through its web interface or management console
  3. 3. For PM5560: Download firmware version 2.7.8 or later from Schneider Electric's download portal (download.schneider-electric.com)
  4. 4. For PM5561: Download firmware version 10.7.3 or later from Schneider Electric's download portal
  5. 5. For PM5562: Download firmware version 2.5.5 or later from Schneider Electric's download portal
  6. 6. For PM5563: Download firmware version 2.7.8 or later from Schneider Electric's download portal
  7. 7. For PM8ECC: Contact Schneider Electric directly for available firmware updates - all versions are affected
  8. 8. Review Schneider Electric security notification for complete version details before upgrading
Caveat Firmware upgrades may require downtime and could affect device configuration; review release notes before applying
