How to Fix CVE-2019-10778

To remediate this vulnerability, upgrade all affected Devcert sanscache dependencies to a patched release. Both direct and transitive dependencies should be checked, as frameworks or security libraries may pull in vulnerable versions transitively.

devcert-sanscache fixed: 0.4.7 
npm install devcert-sanscache@0.4.7
Verify Direct and Transitive Dependencies

Run the following command in your project directory to verify that all resolved dependencies use the patched release: 

npm ls devcert-sanscache

How to Check if You Are Affected

To determine whether your Node.js application is affected by CVE-2019-10778, inspect your project dependencies using npm:

npm ls devcert-sanscache

Analyze the terminal output to locate any version of Devcert sanscache in your dependency tree. If any resolved version matches the vulnerable ranges listed in the table below (for example, versions earlier than 0.4.7), your application is affected.

Note: The npm ls devcert-sanscache command inspects dependencies declared in your package.json and lockfile; it does not perform automated runtime dynamic scanning.

Technical Details

Vulnerability Mechanism & Technical Analysis

This vulnerability is classified under CWE-78: Improper Neutralization of Special Elements used in an OS Command ('OS Command Injection'), where the product constructs all or part of an os command using externally-influenced input from an upstream component, but it does not neutralize or incorrectly neutralizes special elements that could modify the intended os command when it is sent to a downstream component. In Devcert sanscache, software state validation or input boundaries are circumvented during processing. Review the official source advisory statement below for specific affected components, classes, and reproduction details.

Source Advisory Statement

devcert-sanscache before 0.4.7 allows remote attackers to execute arbitrary code or cause a Command Injection via the exec function. The variable `commonName` controlled by user input is used as part of the `exec` function without any sanitization.
