How to Fix CVE-2024-25354

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

domain-suffix fixed: Latest secure release 
npm install domain-suffix@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 domain-suffix

How to Check if You Are Affected

To determine whether your Node.js application is affected by CVE-2024-25354, inspect your project dependencies using npm:

npm ls domain-suffix

Analyze the terminal output to locate any version of Domain suffix 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 domain-suffix 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-1333: Inefficient Regular Expression Complexity, where the product uses a regular expression with a worst-case computational complexity that is inefficient and possibly exponential. In Domain suffix, 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

RegEx Denial of Service in domain-suffix 1.0.8 allows attackers to crash the application via crafted input to the parse function. ## PoC ```js async function exploit() { const domainsuffix = require(\"domain-suffix\"); // Crafting a string that will cause excessive backtracking const maliciousInput = \"a.\".repeat(10000) + \"b\"; // This will create a long sequence of \"a.\" followed by \"b\" const result = await domainsuffix.domainSuffix.parse(maliciousInput); } await exploit(); ```
