FOG is a free open-source cloning/imaging/rescue suite/inventory management system. Prior to 1.5.10.1870, the management adInfo() endpoint in packages/web/lib/fog/fogpage.class.php was reported to return the FOG_AD_DEFAULT_PASSWORD value in its domainpass JSON field and to be dispatchable through node=ipxe without an authenticated session. The response was also consumed by host and group Active Directory configuration interfaces. This could disclose the default domain-join credential to a remote unauthenticated requester. This vulnerability is fixed in 1.5.10.1870.

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.

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".
