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

This critical-severity CVE scores 9.8 under NVD CVSS v3. EPSS exploit probability: 6.9% (94th percentile of EPSS-scored CVEs). GitHub Security Advisory CVSS 6.3 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 2025-05-20) is not newer than that change (2026-06-17), so it does not.

The CVE record's description, written by its CNA (VulDB), states the affected versions: "A vulnerability was found in Linksys FGW3000-AH and FGW3000-HK up to 1.0.17.000000." No release containing a fix is confirmed on record.

A vulnerability was found in Linksys FGW3000-AH and FGW3000-HK up to 1.0.17.000000. It has been classified as critical. This affects the function control_panel_sw of the file /cgi-bin/sysconf.cgi of the component HTTP POST Request Handler. The manipulation of the argument filename leads to command injection. It is possible to initiate the attack remotely. The exploit has been disclosed to the public and may be used. The vendor was contacted early about this disclosure but did not respond in any way.

EG Risk 47/100

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 every mission impact level.

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.

Exploitation none (CISA Vulnrichment) · Automatable no (CISA Vulnrichment) · Technical impact partial (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". CISA's decision table

BOD 26-04 (CISA's remediation timeline, Table 1)60 days if the affected system is publicly exposed; Fix on system upgrade if it is not.

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. Until a fixed release is applied, mitigate as this page's verdict says. In the directive's words, “Fix on system upgrade” means that, “unless conditions change”, the vulnerability “should be remediated the next time the vulnerable asset receives a scheduled major upgrade or rebuild”: its timelines are “dynamic as facts change”, and a KEV listing shortens them.

(refreshed 14× in last 7d / 51× 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 244 rows on record for this CVE, as 98 entries (2 repeats merged).

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. 2 repeat rows among the latest 100 are merged into the row they repeat. The 144 oldest rows on record are not shown and were not checked, so the counts can still include repeats.

Frequently asked(5)

What is CVE-2025-5000?
CVE-2025-5000 is a critical-severity vulnerability; its CVE record was published on May 20, 2025. A vulnerability was found in Linksys FGW3000-AH and FGW3000-HK up to 1.0.17.000000. It has been classified as critical. This affects the function control_panel_sw of the file /cgi-bin/sysconf.cgi of the component HTTP POST Request Handler. The manipulation of the argument filename leads to command…
When was the CVE record for CVE-2025-5000 published?
The CVE record for CVE-2025-5000 was published on May 20, 2025. That is the record's publication date; the vulnerability itself may have been made public earlier. EchelonGraph's copy of the record carries a last-modified date of June 17, 2026; the record at its source may have been updated since.
Is CVE-2025-5000 actively exploited?
CVE-2025-5000 is not currently on CISA's Known Exploited Vulnerabilities catalog. FIRST EPSS estimates a 6.9% probability of exploitation in the next 30 days (94th percentile of EPSS-scored CVEs).
What is the CVSS score of CVE-2025-5000?
CVE-2025-5000 has a CVSS v3 base score of 9.8 (NVD).
How do I remediate CVE-2025-5000?
No fix for CVE-2025-5000 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 description, written by its CNA (VulDB), states the affected versions: "A vulnerability was found in Linksys FGW3000-AH and FGW3000-HK up to 1.0.17.000000." No release containing a fix is confirmed on record.
