• View a list of your weaknesses, including the following information:

  • Weakness Name — The Common Vulnerability Exposure (CVE) ID associated with the weakness.

  • Description — A brief description of the weakness.

  • Weakness Type — The type of weaknesses: Misconfiguration or Vulnerability.

  • Severity — The severity of the weakness, for example, Critical.

    Note: At this time, Tenable Exposure Management does not include information for Info level severity weaknesses.
    Note: Because Tenable Exposure Management calculates CVEs using VPR and Tenable Cloud Security calculates using CVSS, you may notice a difference in severity across weaknesses between these applications.

  • VPR Score — The Vulnerability Priority Rating (VPR) of the weakness.

  • Impacted Assets — The number of assets impacted by the weakness. For more information, see Assets.

  • Top Attack Techniques — Instances of MITRE Att&ck techniques associated with this asset that are used in attack paths leading to critical assets. For more information, see Top Attack Techniques.

    Tip: Click a choke point to navigate directly to the Attack Techniques tab on the Attack Path page, filtered automatically by techniques that feature the weakness.
    Note: Because Tenable Exposure Management aggregates techniques by cause (for example, CVE, CWE) a single choke point may have multiple sources/targets. This may cause discrepancies in technique counts between the Weaknesses tab and the sum of choke points within the Top Attack Techniques tab.

  • Last seen — The date at which the weakness was last seen in a scan on the asset.

  • Sources — The application the weakness' asset originated from, for example, Tenable Vulnerability Management.

  • Click See details to view more details about a weakness. For more information, see View Weakness Details.
