The top 5 known vulnerabilities that are a threat to your security posture

Every year, fullstack vulnerability management provider Edgescan releases its Vulnerability Statistics Report, which highlights the highest impact vulnerabilities still out there in the wild. As a teaser to their 2021 report, their team has compiled a useful list of the top 5 known, unpatched vulnerabilities leveraged by cybercriminals in order launch attacks on unsuspecting organisations.

The list includes the CVE, its impact and the threat actors taking advantage of the vulnerabilities.

4. CVE-2017-5715 - Also known as Spectre
CVSS 2 Score 
4.7
Impacted Systems 
ARM, Intel
Description: 
Systems with microprocessors utilizing speculative execution and indirect branch prediction may allow unauthorized disclosure of information to an attacker with local user access via a side-channel analysis.
Impact:  
A local user can run specially crafted code to cause the CPU to speculatively execute an indirect branch to leak memory contents from another process into a CPU cache and then read the contents of the cache [CVE-2017-5715]. A local user can view arbitrary virtual memory contents on the target CPU device [which can lead to elevated privileges on the target system]
Threat Actor
