Cybercriminals are forever on the hunt for the latest software vulnerabilities to exploit. Cybersecurity professionals race to patch them up. But with more than 12,000 common vulnerabilities and exposures (CVEs) reported in 2019, knowing which to focus on can be a daunting prospect.
To help infosec workers prioritise, researchers at cybersecurity firm Recorded Future analysed last year’s top vulnerabilities to create a list of the top ten most commonly exploited software vulnerabilities of 2019.
Eight out of 10 security flaws affected Microsoft, with four of those targeting Windows Explorer. The remaining two target Adobe Flash Player, with one Adobe vulnerability the most exploited of the year.
Meanwhile, six of the vulnerabilities were from 2018, suggesting companies and individuals are not being proactive enough in rolling out fixes.
The good news is that there are patches available for all of the ten most exploited software vulnerabilities of 2019.
Here are the top ten software flaws, in order of most exploited. For more information and advice, the full Recorded Future report can be found here.
