PowerLogic ION9000: Cleartext Transmission of Sensitive Information
CVE-2022-46680 is a critical-severity cleartext transmission of sensitive information vulnerability in PowerLogic ION9000 from Schneider Electric, with a CVSS 3.1 base score of 9.8 out of 10. It can be exploited remotely over the network by an unauthenticated attacker, without any action from a user. Affected PowerLogic ION9000 versions: Prior to 4.0.0. The record does not name a fixed version, so check the vendor advisory. There is no confirmed exploitation so far. EPSS estimates a 0.38% chance of exploitation within 30 days, which is low compared with other CVEs.
Critical severity: a successful attack would have severe impact.
What to do
- Update Powerlogic Ion9000 Firmware to 4.0.0 or a later version.
- Update Powerlogic Ion7400 Firmware to 4.0.0 or a later version.
- Update Powerlogic Pm8000 Firmware to 4.0.0 or a later version.
- Read the advisory on download.schneider-electric.com for workarounds and exact fixed builds.
- Until you can update, restrict network access to the affected service so it is not reachable from untrusted networks.

Official description
A CWE-319: Cleartext transmission of sensitive information vulnerability exists that could cause disclosure of sensitive information, denial of service, or modification of data if an attacker is able to intercept network traffic.
Source: the CVE record as published by its numbering authority, via NVD and CVE.org.
The underlying weakness: Cleartext Transmission of Sensitive Information
The product transmits sensitive or security-critical data in cleartext in a communication channel that can be sniffed by unauthorized actors.
How developers prevent this class of flaw
- Before transmitting, encrypt the data using reliable, confidentiality-protecting cryptographic protocols.
- When using web applications with SSL, use SSL for the entire session from login to logout, not just for the initial login page.
- When designing hardware platforms, ensure that approved encryption algorithms (such as those recommended by NIST) protect paths from security critical data to trusted user applications.
