An online search engine for the CVE vulnerabilities database. Users may select from any combination of vendor, product, vulnerability source, type or consequence to generate a list of documented vulnerabilities. Each entry provides a link to detailed information, thus providing an excellent tool for anyone seeking an up-to-date list of known security problems for their system components. Originally introduced as the ICAT Metabase in 1999, the product's search structure was completely rewritten and enhanced in 2005. To use the database, visit http://nvd.nist.gov.
