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
An unauthenticated remote attacker can DoS the control agent due to a out-of-bounds read which may prevent or disrupt the charging functionality. 

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

An unauthenticated remote attacker can cause a denial of service on the control agent by exploiting an out-of-bounds read vulnerability. This can prevent or disrupt charging functionality, likely in an EV charging or similar battery charging system.

MitigationApply vendor-provided security patches to the control agent software as soon as available. Until a patch is released, consider network segmentation to limit exposure of the control agent to untrusted networks and monitor for service disruptions.

Verify against the referenced sources before acting — the references below are authoritative for this CVE, this summary is not.

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 Charx Sec model
    Locate the physical device label or check the device inventory/management interface to confirm whether the unit is a Charx Sec 3000, 3050, 3100, or 3150 model.
    Affected if The model is any of the four affected variants (3000, 3050, 3100, 3150).
  2. Determine the installed firmware version
    Access the device web interface, management console, or use the vendor's configuration tool to retrieve the current firmware version. Compare against the affected range.
    Affected if The firmware version is lower than 1.5.1 (e.g., 1.4.x, 1.3.x, etc.).
  3. Verify the control agent network exposure
    Check the device network configuration to determine whether the control agent service is listening on network interfaces accessible from untrusted networks.
    Affected if The control agent is bound to IP addresses reachable from untrusted or external networks.
  4. Confirm the control agent service is active
    Verify that the control agent service is running on the device. This may be observable through the management interface status page or by querying the device diagnostics.
    Affected if The control agent service is currently running and processing requests.

You are affected if you have a Charx Sec 3000/3050/3100/3150 device running firmware below version 1.5.1 with the control agent accessible to untrusted networks.

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 1.5.1 or later
Fixed in 1.5.1
Interim mitigation

Apply vendor-provided security patches to the control agent software as soon as available. Until a patch is released, consider network segmentation to limit exposure of the control agent to untrusted networks and monitor for service disruptions.

Recommended fix High confidence

Charx Sec 3000/3050/3100/3150 Firmware version 1.5.1

  1. 1. Obtain the Charx Sec 3000/3050/3100/3150 firmware version 1.5.1 from the vendor (Charx)
  2. 2. Review the vendor's firmware upgrade instructions for your specific device model
  3. 3. Backup current device configuration if supported
  4. 4. Upload and install firmware version 1.5.1 following vendor documentation
  5. 5. Verify the firmware installation was successful
  6. 6. Confirm the control agent is operational and charging functionality is restored
Caveat Review vendor release notes for any configuration or compatibility changes between your current version and 1.5.1

Generated from the published advisory — verify against the referenced sources before acting.
