$2.19M = $4.99M incident cost x 1 exposure x 0.43796 likelihood

udv@v1 · unaudited · wrong for you until you say what you run

$4.99M is the cost of a breach that happened, from IBM Cost of a Data Breach Report 2026, global average. It is not the value of any asset of yours. That average already covers breaches of every severity, so scaling it by exposure understates a partial-impact record. That is an assumption, not a measurement. Your own asset value goes in the decision record.

Foresight · where to check next

No weakness class or product neighbourhood is held for this record, so this index cannot name anywhere to check next. That is an absence in the record, not a finding about the software.

Patch available sinceNo dated patch-availability record in held sources. The index holds reference URLs without dates and only the current revision of the CVE record, so the day a fix first existed cannot be derived. Only the versions it landed in.

A rung lights from a row in the index, never from an assessment. "Held sources" is the true scope of the claim: this index reads the CVE record, NVD, CISA KEV, FIRST's EPSS and public proof-of-concept repositories, and it does not observe attacks.

What it is stated by the CNA

Windows Shell for Microsoft Windows 2000 SP4, XP SP1 and SP2, and Server 2003 allows remote attackers to execute arbitrary commands via a shortcut (.lnk) file with long font properties that lead to a buffer overflow in the Client/Server Runtime Server Subsystem (CSRSS), a different vulnerability than CVE-2005-2118. receipt
