CVE-2020-25184 — Schneider-Electric Easergy T300 Firmware security vulnerability

High CVSS 7.8

Rockwell Automation ISaGRAF Runtime Versions 4.x and 5.x stores the password in plaintext in a file that is in the same directory as the executable file. ISaGRAF Runtime reads the file and saves the data in a variable without any additional modification. A local, unauthenticated attacker could compromise the user passwords, resulting in information disclosure.

Matched remediation archetype

Information disclosure and sensitive data exposure

This catalog composition supplies bounded fallback guidance. Explicitly reviewed curated workflows load with the complete record below.

Check exposure

  • Trace sensitive data through responses, errors, logs, metrics, traces, caches, exports, files, backups, and client bundles.
  • Identify affected subjects, tenants, retention windows, access controls, and downstream copies without opening unnecessary sensitive records.
  • Review metadata, timing, status, length, and existence signals as well as direct content disclosure.

Remediate safely

  • Minimize collection and output, apply field-level authorization and redaction at a centralized boundary, and return generic external errors.
  • Remove secrets and sensitive data from logs, artifacts, URLs, caches, and client-side bundles; rotate credentials that may have been exposed.
  • Update the affected component and add synthetic-data tests for response, error, observability, and export paths.
