How to Fix CVE-2016-10660

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

fis-parser-sass-bin fixed: Latest secure release 
npm install fis-parser-sass-bin@Latest secure release
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 fis-parser-sass-bin

How to Check if You Are Affected

To determine whether your Node.js application is affected by CVE-2016-10660, inspect your project dependencies using npm:

npm ls fis-parser-sass-bin

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

Note: The npm ls fis-parser-sass-bin 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-311: Missing Encryption of Sensitive Data, where the product does not encrypt sensitive or critical information before storage or transmission. In Fis parser sass bin, 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

Affected versions of `fis-parser-sass-bin` insecurely download an executable over an unencrypted HTTP connection. In scenarios where an attacker has a privileged network position, it is possible to intercept the response and replace the executable with a malicious one, resulting in code execution on the system running `fis-parser-sass-bin`. ## Recommendation No patch is currently available for this vulnerability. The best mitigation is currently to avoid using this package, using a different package if available. Alternatively, the risk of exploitation can be reduced by ensuring that this package is not installed while connected to a public network. If the package is installed on a private network, the only people who can exploit this vulnerability are those who have compromised your network or those who have privileged access to your ISP, such as Nation State Actors or Rogue ISP Employees.
