“—” 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: 1.8% (78th 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 2022-10-20) is not newer than that change (2025-01-14), so it does not.

The CVE record's CNA (Synology Inc.) lists Synology DiskStation Manager (DSM) versions before 7.1.1-42962-2 as affected. No release containing a fix is confirmed on record.

A vulnerability regarding improper restriction of operations within the bounds of a memory buffer is found in the message processing functionality of Out-of-Band (OOB) Management. This allows remote attackers to execute arbitrary commands via unspecified vectors. The following models with Synology DiskStation Manager (DSM) versions before 7.1.1-42962-2 may be affected: DS3622xs+, FS3410, and HD6500.

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 the vendor's advisory for a fixed release; until one is applied, restrict network exposure of the affected system or apply the vendor's mitigation 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.

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 it from the CNA feed. 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). Most recent first.

Showing the most recent 99 of 238 refreshes 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. 1 repeat row among the latest 100 is merged into the row it repeats. The 139 oldest rows on record are not shown and were not checked, so the counts can still include repeats.

Frequently asked(5)

What is CVE-2022-27625?
CVE-2022-27625 is a critical-severity vulnerability; its CVE record was published on October 20, 2022. A vulnerability regarding improper restriction of operations within the bounds of a memory buffer is found in the message processing functionality of Out-of-Band (OOB) Management. This allows remote attackers to execute arbitrary commands via unspecified vectors. The following models with Synology…
When was CVE-2022-27625 made public?
CVE-2022-27625 was made public on October 20, 2022: that is the date its CVE record's CNA, Synology Inc., gives for when the vulnerability was made public. The CVE record itself was published on October 20, 2022. EchelonGraph's copy of the record carries a last-modified date of January 14, 2025; the record at its source may have been updated since.
Is CVE-2022-27625 actively exploited?
CVE-2022-27625 is not currently on CISA's Known Exploited Vulnerabilities catalog. FIRST EPSS estimates a 1.8% probability of exploitation in the next 30 days (78th percentile of EPSS-scored CVEs).
What is the CVSS score of CVE-2022-27625?
CVE-2022-27625 has a CVSS v3 base score of 10.0 (NVD).
How do I remediate CVE-2022-27625?
No fix for CVE-2022-27625 is confirmed yet. Until one is published, restrict network exposure of the affected system or apply the vendor's mitigation — for example, keep it off the internet or limit it to trusted networks — and watch the vendor's advisory for the fix. The CVE record's CNA (Synology Inc.) lists Synology DiskStation Manager (DSM) versions before 7.1.1-42962-2 as affected. No release containing a fix is confirmed on record.
