CVE-2025-25269
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 · uneditedAn unauthenticated local attacker can inject a command that is subsequently executed as root, leading to a privilege escalation.
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 confidenceA local command injection vulnerability allows an unauthenticated attacker to inject arbitrary commands that execute with root privileges, resulting in complete system compromise through privilege escalation.

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 checksWork through these to decide whether this CVE applies to you.
-
Identify the Charx Sec model numberLocate the physical device label or access the management interface to confirm the model (3000, 3050, 3100, or 3150)Affected if The model is one of the four affected variants (3000, 3050, 3100, 3150)
-
Retrieve the firmware versionAccess the device web interface or CLI and check the firmware version under System Information or use the command 'show version'Affected if The installed firmware version is lower than 1.7.3 for the identified model
-
Verify the firmware version formatConfirm the version number is displayed as a three-part version (e.g., 1.7.2, 1.6.0) and not a different versioning schemeAffected if The version shows as < 1.7.3 (e.g., 1.7.2, 1.6.0, 1.5.1)
-
Check for local network exposureReview network configuration to determine if the device management interface is accessible from untrusted networksAffected if The device management interface is exposed beyond trusted local access
If the device is a Charx Sec 3000/3050/3100/3150 running firmware version below 1.7.3 and local command injection can be triggered through an accessible interface, the environment is affected by this vulnerability.

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 · scoped1.7.3
Apply vendor patches immediately. Restrict local access to trusted users as an interim control until patching can be completed.
Charx Sec Firmware 1.7.3 (all models: 3000, 3050, 3100, 3150)
- Obtain Charx Sec firmware version 1.7.3 from the official vendor source (charx.io) or the reference source (certvde.com)
- Verify the firmware integrity using provided checksums if available
- Access the Charx Sec device web management interface or CLI
- Navigate to the firmware update section (usually under Settings > Firmware or Administration > Software Update)
- Upload the firmware file version 1.7.3
- Apply the firmware update and wait for the upload and installation to complete
- Reboot the device if not automatically performed
- Verify the firmware version is now 1.7.3 in the device management interface
