How to Fix CVE-2018-3783

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

flintcms fixed: 1.1.10 
npm install flintcms@1.1.10
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 flintcms

How to Check if You Are Affected

To determine whether your Node.js application is affected by CVE-2018-3783, inspect your project dependencies using npm:

npm ls flintcms

Analyze the terminal output to locate any version of Flintcms in your dependency tree. If any resolved version matches the vulnerable ranges listed in the table below (for example, versions earlier than 1.1.10), your application is affected.

Note: The npm ls flintcms 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-89: Improper Neutralization of Special Elements used in an SQL Command ('SQL Injection'), where the product constructs all or part of an sql command using externally-influenced input from an upstream component, but it does not neutralize or incorrectly neutralizes special elements that could modify the intended sql command when it is sent to a downstream component. without sufficient removal or quoting of sql syntax in user-controllable inputs, the generated sql query can cause those inputs to be interpreted as sql instead of ordinary user data. In Flintcms, 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

Versions of `flintcms` before version 1.1.10 are vulnerable to account takeover due to blind MongoDB injection in the password reset. ## Recommendation Update to version 1.1.10 or later.
