Manage third-party vulnerabilities

After you enable and configure the Application Security and OneAgent features, Dynatrace starts monitoring your applications to detect vulnerabilities in third-party libraries.

• A spinning radar screen in the upper-right corner of the Third-party vulnerabilities page indicates that your environment is being monitored. If the radar stops, you are warned that Monitoring stopped. Please check settings. Follow the associated link to enable Vulnerability Analytics.

  

• The security problem indicator on the Dynatrace top bar displays the number of critical or high vulnerabilities in your environment. Select it to navigate to the Third-party vulnerabilities page.

Vulnerabilities detected

A list of all detected third-party vulnerabilities in your environment. To sort the list by any item, select the corresponding column heading. To add or remove column headings, select Format table.

Vulnerability

• The Dynatrace vulnerability ID (example: S-3440)

• Depending on the vulnerability feed:

  • For SNYK vulnerabilities, the SNYK name (example: Denial of Service (DoS))
  • For NVD vulnerabilities, the CVE ID (example: CVE-2020-2805), or the CWE name, if available (example: Deserialization of Untrusted Data)

  For more information, see Terminology: Third-party vulnerability.

• The vulnerable component (the software or runtime package causing a vulnerability):

  • For SNYK vulnerabilities, the package name (example: org.apache.tomcat:tomcat-coyote)
  • For NVD vulnerabilities, the runtime technology (examples: Java runtime, Node.js runtime)

Davis Security Score

• The risk level (Critical, High, Medium, Low, None) of the vulnerability, based on the Common Vulnerability Scoring System (CVSS) score of the vulnerability and AI-enhanced to take public internet exposure and reachable data assets into consideration. If a vulnerability has been resolved, the symbol color is green.

• The overall risk assessment (the final score).

• If there is any public exposure (the vulnerability affects a process that is exposed to the internet, based on the Dynatrace entity model (Smartscape)). If the symbol is grayed out and crossed out, there's no public exposure. If the symbol isn't present, there's no data available.

• If there are any reachable data assets (the vulnerability affects a process that has database access, based on the Dynatrace entity model). If the symbol is grayed out and crossed out, there are no reachable data assets affected. If the symbol isn't present, there's no data available.

• If there is any vulnerable function in use by a process. If the symbol is grayed out and crossed out, there's no vulnerable function in use. If the symbol isn't present, there's no data available.

• If there is any public exploit (a known malicious code that exploits this vulnerability). If the symbol is grayed out and crossed out, there's no public exploit. If the symbol isn't present, there's no data available.

Status

• Open: The vulnerability is active.

• Resolved: The vulnerability has been closed automatically because the root cause (for example, loading a vulnerable library) is no longer present. For more information, see Terminology: Resolved vulnerabilities.

• Muted - Open: The vulnerability is active but has been silenced by request.

• Muted - Resolved: The silenced active vulnerability has been closed automatically because the root cause (for example, loading a vulnerable library) is no longer present.

  Note: A muted vulnerability that has been closed automatically doesn't change its status to Resolved, but to Muted - Resolved.

Process group overview

Displays the following information, based on the last hour:

Process groups

• Process groups in total: The total number of process groups that are related (affected, resolved, and muted) to the identified vulnerability. It links to the overview page of the related process groups.

• Affected process groups: The number of affected process groups and the percentage of affected process groups out of the total number of related process groups. It links to the overview page of related process groups filtered by Status: Affected.

  Notes:

  • An affected process group is a process group that contains a vulnerable library or runtime.

  • The affected process groups are globally calculated. Management zone filtering doesn't apply.

  • The number of affected process groups matches the total count only if all functions in all used software component versions are vulnerable.

    Example

    A software component A is vulnerable to a vulnerability X in versions 1 and 2.

    The function f1 is only vulnerable in version 1.

    There are two process groups:

    • Process group PG1 uses the software component A.1, which includes the vulnerable function f1.
    • Process group PG2 uses the software component A.2, which doesn't include any vulnerable function.

    The Process groups overview section on the details page of a vulnerability will show the vulnerable function f1 with one process group (PG1) In use and Not in use. PG2 is not considered because there is no vulnerable function in version 2.

• Resolved process groups: The number of affected process groups that have been resolved and the percentage of resolved process groups out of the total number of related process groups. It links to the overview page of related process groups filtered by Status: Resolved.

• Muted process groups: The number of affected process groups that have been muted and the percentage of muted process groups out of the total number of related process groups. It links to the overview page of related process groups filtered by Status: Muted.

• A graph displaying the affected, resolved, and muted process groups, marked with different colors.

Processes

• Processes total: The total number of processes (affected and unaffected) out of the process groups where at least one process is affected.

• Affected processes: The number of affected processes.

  Note: An affected process is a process that contains a vulnerable library or runtime. It can be exposed to the public internet or not.

• Exposed: The number of affected processes that are exposed to the public internet and the percentage of exposed processes out of the total number of affected processes.

Most affected process groups

Lists and links to the top five process groups, sorted by status (Affected, then Resolved, and then Muted) and amount of affected processes out of the total processes in the respective process group, and indicates if there is any public exposure, or if there are any reachable data assets. Select View all process groups to navigate to the overview page of the process groups related to a vulnerability.
