CVE-2020-7510
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 · uneditedA CWE-200: Information Exposure vulnerability exists in Easergy T300 (Firmware version 1.5.2 and older) which could allow attacker to obtain private keys.
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 CWE-200 Information Exposure vulnerability in Schneider Electric's Easergy T300 firmware (version 1.5.2 and older) allows attackers to obtain private keys, likely due to improper storage or exposure of cryptographic material within the device firmware or configuration.

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 Easergy T300 firmware versionAccess the device's web interface, console, or management interface and locate the firmware version information. This is typically found in System Info, About, or Device Status pages.Affected if The displayed firmware version is 1.5.2 or older
-
Compare version against affected rangeDocument the exact firmware version number found and compare it to the affected range: any version <= 1.5.2 is considered vulnerable.Affected if The installed version is 1.5.2 or any earlier version number
-
Inspect for exposed cryptographic materialExamine the device firmware image, configuration files, or backup exports for any private key files (.key, .pem, privatekey*), SSL/TLS certificates with matching private keys, or cryptographic key material stored in plain text.Affected if Private keys, certificate files, or other cryptographic secrets are found within the device firmware, configuration, or backup files
A user is affected if their Easergy T300 device runs firmware version 1.5.2 or older, or if private key or cryptographic material is found exposed in the device firmware or configuration.

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.
From vendor dataUpgrade Easergy T300 firmware to a version newer than 1.5.2 that addresses the private key exposure. If upgrade is not immediately possible, restrict network access to the device and monitor for unauthorized access.
