Proficy CIMPLICITY: Cleartext Transmission of Sensitive Information
CVE-2022-21798 is a critical-severity cleartext transmission of sensitive information vulnerability in Proficy CIMPLICITY from General 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 Proficy CIMPLICITY versions: all. The record does not name a fixed version, so check the vendor advisory. There is no confirmed exploitation so far. EPSS estimates a 0.61% 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
- Check which version of Proficy CIMPLICITY you run against the affected versions below, and install the vendor's latest release.
- Until you can update, restrict network access to the affected service so it is not reachable from untrusted networks.

Official description
The affected product is vulnerable due to cleartext transmission of credentials seen in the CIMPLICITY network, which can be easily spoofed and used to log in to make operational changes to the system.
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.
