“—” beside the score: it is equal to NVD's CVSS score.

This critical-severity CVE scores 10.0 under NVD CVSS v3. EPSS exploit probability: 1.5% (74th percentile of EPSS-scored CVEs). GitHub Security Advisory CVSS 9.8 is lower than this score; a lower GitHub score revises it only when its advisory is newer than the CVE record's last change, and this advisory (published 2022-09-25) is not newer than that change (2024-11-21), so it does not.

The CVE record's CNA (Cybersecurity and Infrastructure Security Agency (CISA) Industrial Control Systems (ICS)) lists MZ Automation libIEC61850 versions up to and including 1.4 as affected. No release containing a fix is confirmed on record.

MZ Automation's libIEC61850 (versions 1.4 and prior; version 1.5 prior to commit a3b04b7bc4872a5a39e5de3fdc5fbde52c09e10e) does not sanitize input before memcpy is used, which could allow an attacker to crash the device or remotely execute arbitrary code.

EG Risk 61/100

EG Risk is EchelonGraph's 0–100 priority score. It fuses impact severity (EG Severity, the CVSS base score, never the KEV-floored or EPSS-lifted EG Score) with real-world exploitation and automatability, under weights EchelonGraph set by hand, so you can rank equal-severity CVEs and fix the most dangerous first. Higher = act sooner.

SSVC (CISA's decision table, applied by EchelonGraph)Track at low or medium mission impact; Attend at high (mission-essential systems).

No fix is confirmed yet. Check with the vendor for a fixed release; until one is applied, restrict network exposure of the affected system on your normal schedule at low or medium mission impact and sooner than that at high.

Exploitation none (CISA Vulnrichment) · Automatable yes (CISA Vulnrichment) · Technical impact total (CISA Vulnrichment). All three are CISA's SSVC values (Vulnrichment). EchelonGraph applied CISA's decision table to them; CISA publishes SSVC inputs and the table, not a decision for each CVE. Mission impact is CISA's Mission & Well-being decision point, and only you can judge it. CISA's table makes it high when Mission Prevalence is Essential — the vulnerable component "directly provides capabilities that constitute at least one MEF for at least one entity" (MEF: mission essential function) — or when Public Well-Being Impact is Irreversible: "multiple fatalities are likely", the cyber-physical system "is likely lost or destroyed", "extreme or serious externalities" are imposed on other parties, or social systems such as elections or the financial grid "are destabilized and potentially collapse".

No released fix is confirmed on this page, but CISA's timeline does not wait for a fix's release: it starts when an agency identifies the flaw on an asset and updates the CDM Agency and Federal Dashboard, and the directive counts patching, decommissioning the system or another action as remediation.

(refreshed 14× in last 7d / 61× in last 30d)

Each row is a time one of our pipelines fetched, updated or re-scored this CVE. For example, "NVD update" means NVD published or revised its analysis for this CVE; "MITRE cvelistV5" means we ingested or refreshed its CVE.org record (CNA or CISA ADP). An arrow marks a change the record states ("CVSS v3 → 9.1"); EPSS and GHSA rows show the values recorded at that time, not what changed (EPSS values are rounded; hover one for the exact figures). "EchelonGraph re-scored" is our own recompute of this CVE's score, not an update from a source, and is not counted in the refreshes above. Most recent first.

Showing the most recent 100 of 289 rows on record for this CVE.

A repeat, a row identical to one the same pipeline wrote less than 10 seconds earlier, is not a separate refresh and is not counted. None are among the latest 100 rows. The 189 oldest rows on record are not shown and were not checked, so the counts can still include repeats.

Frequently asked(5)

What is CVE-2022-2970?
CVE-2022-2970 is a critical-severity vulnerability; its CVE record was published on September 23, 2022. MZ Automation's libIEC61850 (versions 1.4 and prior; version 1.5 prior to commit a3b04b7bc4872a5a39e5de3fdc5fbde52c09e10e) does not sanitize input before memcpy is used, which could allow an attacker to crash the device or remotely execute arbitrary code.
When was CVE-2022-2970 made public?
CVE-2022-2970 was made public on September 8, 2022: that is the date its CVE record's CNA, Cybersecurity and Infrastructure Security Agency (CISA) Industrial Control Systems (ICS), gives for when the vulnerability was made public. The CVE record itself was published on September 23, 2022. EchelonGraph's copy of the record carries a last-modified date of November 21, 2024; the record at its source may have been updated since.
Is CVE-2022-2970 actively exploited?
CVE-2022-2970 is not currently on CISA's Known Exploited Vulnerabilities catalog. FIRST EPSS estimates a 1.5% probability of exploitation in the next 30 days (74th percentile of EPSS-scored CVEs).
What is the CVSS score of CVE-2022-2970?
CVE-2022-2970 has a CVSS v3 base score of 10.0 (NVD).
How do I remediate CVE-2022-2970?
No fix for CVE-2022-2970 is confirmed yet. Until one is published, restrict network exposure of the affected system — for example, keep it off the internet or limit it to trusted networks — and watch for a fix. The CVE record's CNA (Cybersecurity and Infrastructure Security Agency (CISA) Industrial Control Systems (ICS)) lists MZ Automation libIEC61850 versions up to and including 1.4 as affected. No release containing a fix is confirmed on record.
