CVE-2022-30313
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 · uneditedHoneywell Experion PKS Safety Manager through 2022-05-06 has Missing Authentication for a Critical Function. According to FSCT-2022-0051, there is a Honeywell Experion PKS Safety Manager multiple proprietary protocols with unauthenticated functionality issue. The affected components are characterized as: Honeywell Experion TCP (51000/TCP), Safety Builder (51010/TCP). The potential impact is: Manipulate controller state, Manipulate controller configuration, Manipulate controller logic, Manipulate controller files, Manipulate IO. The Honeywell Experion PKS Distributed Control System (DCS) Safety Manager utilizes several proprietary protocols for a wide variety of functionality, including process data acquisition, controller steering and configuration management. These protocols include: Experion TCP (51000/TCP) and Safety Builder (51010/TCP). None of these protocols have any authentication features, allowing any attacker capable of communicating with the ports in question to invoke (a subset of) desired functionality. There is no authentication functionality on the protocols in question. An attacker capable of invoking the protocols' functionalities could achieve a wide range of adverse impacts, including (but not limited to), the following: for Experion TCP (51000/TCP): Issue IO manipulation commands, Issue file read/write commands; and for Safety Builder (51010/TCP): Issue controller start/stop commands, Issue logic download/upload commands, Issue file read commands, Issue system time change commands. A mitigating factor with regards to some, but not all, of the above functionality is that these require the Safety Manager physical keyswitch to be in the right position.
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 · high confidenceHoneywell Experion PKS Safety Manager through May 2022 contains proprietary protocols (Experion TCP on 51000/TCP and Safety Builder on 51010/TCP) that lack any authentication mechanisms. An attacker with network access to these ports can issue commands for IO manipulation, file read/write operations, controller start/stop, logic download/upload, and system time changes without any credentials.

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 Honeywell Safety Manager on the networkScan network for devices running Honeywell Experion PKS Safety Manager by checking for响应 to probes on ports 51000/TCP and 51010/TCP, or check asset inventory for Honeywell Safety Manager firmware entriesAffected if The device has Honeywell Safety Manager firmware running and responding on the network
-
Check if Experion TCP port 51000/TCP is exposedRun a port scan against the target system to verify port 51000/TCP is open and accepting connectionsAffected if Port 51000/TCP is open and accessible from an untrusted network segment
-
Check if Safety Builder port 51010/TCP is exposedRun a port scan against the target system to verify port 51010/TCP is open and accepting connectionsAffected if Port 51010/TCP is open and accessible from an untrusted network segment
-
Verify network segmentation for exposed portsReview firewall rules, ACLs, or network zone assignments to determine if ports 51000/TCP and 51010/TCP can be accessed from network segments outside the trusted control system networkAffected if These ports are reachable from business networks, DMZs, or external networks without proper access controls
-
Confirm authentication is not implemented on proprietary protocolsAttempt to issue a test command to ports 51000/TCP or 51010/TCP using the proprietary protocol without providing credentials, or review protocol documentation/configuration for authentication settingsAffected if Commands can be issued to the controller without any authentication token or credential
The environment is affected if Honeywell Safety Manager is present with ports 51000/TCP or 51010/TCP accessible from any network segment that is not strictly isolated and protected by authentication controls.

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 dataImplement authentication on the affected proprietary protocols (this may require vendor-supplied patches or updates from Honeywell) and restrict network access to these ports via network segmentation or firewall rules. Physical keyswitch position provides partial mitigation for some functionality.
