The Recent Exploit/Technique table contains a 'Workaround or Patch Available' column that indicates whether a workaround or patch has been published for the vulnerability which the script exploits. The risks levels applied to vulnerabilities in the Cyber Security Bulletin are based on how the 'system' may be impacted. The text in the Risk column appears in red for vulnerabilities ranking High. Updates to items appearing in previous bulletins are listed in bold text. This bulletin provides a summary of new or updated vulnerabilities, exploits, trends, viruses, and trojans. Software vulnerabilities are categorized in the appropriate section reflecting the operating system on which the vulnerability was reported however, this does not mean that the vulnerability only affects the operating system reported since this information is obtained from open-source information. Information in the US-CERT Cyber Security Bulletin is a compilation and includes information published by outside sources, so the information should not be considered the result of US-CERT analysis. Please note that some of the information in the bulletin is compiled from external, open-source reports and is not a direct result of CISA analysis. Patch information is provided when available. This information may include identifying information, values, definitions, and related links. Low: vulnerabilities with a CVSS base score of 0.0–3.9Įntries may include additional information provided by organizations and efforts sponsored by CISA.Medium: vulnerabilities with a CVSS base score of 4.0–6.9.High: vulnerabilities with a CVSS base score of 7.0–10.0.The division of high, medium, and low severities correspond to the following scores:

Vulnerabilities are based on the Common Vulnerabilities and Exposures (CVE) vulnerability naming standard and are organized according to severity, determined by the Common Vulnerability Scoring System (CVSS) standard. Please visit NVD for updated vulnerability entries, which include CVSS scores once they are available.

In some cases, the vulnerabilities in the bulletin may not yet have assigned CVSS scores. The CISA Vulnerability Bulletin provides a summary of new vulnerabilities that have been recorded by the National Institute of Standards and Technology (NIST) National Vulnerability Database (NVD) in the past week.
