Security News > 2021 > July > MITRE updates list of top 25 most dangerous software bugs
MITRE has shared this year's top 25 list of most common and dangerous weaknesses plaguing software throughout the previous two years.
Software weaknesses are flaws, bugs, vulnerabilities, and various other types of errors impacting a software solution's code, architecture, implementation, or design, potentially exposing systems it's running on to attacks.
MITRE developed the top 25 list using Common Vulnerabilities and Exposures data from 2019 and 2020 obtained from the National Vulnerability Database.
MITRE's 2021 top 25 bugs are dangerous because they are usually easy to discover, have a high impact, and are prevalent in software released during the last two years.
The list below provides insight to the community at large into the most critical and current software security weaknesses.
CISA recommends transitioning away from end-of-life software as soon as possible as the easiest and quickest way to mitigate old unpatched security bugs.
