Microsoft and Google software offerings have secured the top spots when it comes to vulnerabilities believed to be best able to disrupt enterprise services and systems today.
According to cybersecurity firm Tenable, the most prevalent vulnerabilities which have been assigned a CVE score and number -- based on update and severity metrics -- have the potential to impact between 20 and 30 percent of enterprises if left unpatched or unresolved.
On Wednesday, the company released the latest Tenable Vulnerability Intelligence Report, which claims that Microsoft .Net and Office, Adobe Flash, and Oracle's Java have the most widespread impact for enterprise assets. In total, half of vulnerability-based enterprise threats are due to problems with Adobe Flash, whereas 20 percent of vulnerabilities belong to Microsoft Office.
When it comes to individual vulnerabilities with the widest impact and severity, however, one particular security flaw in Microsoft apps, CVE-2018-8202, is believed to have the potential to impact 32 percent of enterprises.
The vulnerability, discovered this year, is described as a privilege escalation issue in the .NET framework.

The second top spot belongs to a bug in Google Chrome, CVE-2018-6153. The vulnerability is a stack-based buffer overflow issue caused by improper bounds checking by Skia. If an attacker is able to dupe a victim into opening a specifically crafted website, the overflow bug can be triggered in order to execute arbitrary code or to cause a system crash.
Tenable estimates that 30 percent of enterprise systems could be impacted by such a bug.
In third comes CVE-2015-6136, a vulnerability in Microsoft IE discovered back in 2015. The vulnerability, which is estimated to have the potential to impact 28 percent of enterprises, is described as a flaw which permits the remote execution of code via a crafted website due to scripting engine memory corruption.
The fourth vulnerability believed to have the most impact on the enterprise isCVE-2018-2938, a bug in a component in Oracle's Java which can be used to gain elevated privileges. In total, Tenable estimates this security flaw could impact up to 28 percent of enterprises.

The fifth vulnerability is found in Microsoft apps. CVE-2018-1039 exists in the .NET framework and permits attackers to bypass device guard functionality. This security flaw is believed to have the potential to impact up to 28 percent of organizations.
The remaining 15 vulnerabilities and security problems -- some of which contain a CVE, and others do not -- have also been listed by Tenable as security flaws with the potential to disrupt the enterprise and are described below.
6: No CVE, SSL, 27 percent: SSL 2.0 and/or SSL 3.0 are impacted by cryptographic flaws including an insecure padding scheme.
