How to Fix CVE-2017-15010

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

tough-cookie fixed: 2.3.3 
npm install tough-cookie@2.3.3
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 tough-cookie

How to Check if You Are Affected

To determine whether your Node.js application is affected by CVE-2017-15010, inspect your project dependencies using npm:

npm ls tough-cookie

Analyze the terminal output to locate any version of Tough cookie in your dependency tree. If any resolved version matches the vulnerable ranges listed in the table below (for example, versions earlier than 2.3.3), your application is affected.

Note: The npm ls tough-cookie 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-400: Uncontrolled Resource Consumption, where the product does not properly control the allocation and maintenance of a limited resource. In Tough cookie, 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 `tough-cookie` are susceptible to a regular expression denial of service. The amplification on this vulnerability is relatively low - it takes around 2 seconds for the engine to execute on a malicious input which is 50,000 characters in length. If node was compiled using the `-DHTTP_MAX_HEADER_SIZE` however, the impact of the vulnerability can be significant, as the primary limitation for the vulnerability is the default max HTTP header length in node. ## Recommendation Update to version 2.3.3 or later.
