A deep dive into CISA\u2019s catalog of 311 known exploited vulnerabilities reveals a plethora of vendors who have multiple products affected by several vulnerabilities. We looked into the products with the most vulnerabilities and the maximum CVEs associated with them. Let us take a closer look at the Top 5 worst-affected products.\u00a0<\/strong><\/p>\n

 <\/p>\n

Product Density Map<\/strong><\/h2>\n

\"CISA<\/p>\n

We have already looked at the top vendors affected<\/a>, where Microsoft, Apple, and Google share the top three positions with the most vulnerabilities. When we look at the product density map, however, Google and Microsoft take pole positions, appearing twice in the same list, but for different products. Ruling the roost, Chrome and Exchange Servers share 10 vulnerabilities each. Apple creates a neat divide to the table with 9 vulnerabilities affecting iOS. Chromium V8 and Windows Win32K take up 9 and 7 pieces each to make it the fourth and fifth worst affected products by number of associated vulnerabilities.<\/p>\n

A detailed list of product versions affected is listed at the end of this article as a ready-reckoner that can be referred to during remediation.<\/p><\/blockquote>\n

 <\/p>\n

Google Chrome<\/strong><\/h2>\n

Google Chrome has the highest number of vulnerabilities affecting it. With a total of 10 unique CVEs, it stands atop the product density list, alongside Microsoft Exchange Server.<\/p>\n
