Security readout for executives and security teams
Plain-English summary
This flaw affects older hapi Node.js applications. Certain HTTP date headers can trigger an exception, but the server keeps the connection open until timeout instead of failing quickly. That can tie up resources and create denial-of-service risk for exposed services.
Executive priority
Treat as a targeted maintenance priority for any exposed legacy hapi service. It is not confirmed as actively exploited, but it can affect service availability and should be fixed during the next security update cycle.
Technical view
hapi before 11.1.3 mishandles specific input in If-Modified-Since or Last-Modified headers. The condition raises an illegal access exception and leaves the socket open until the Node timeout, described as two minutes by default. The issue maps to CWE-400 resource consumption.
Likely exposure
Exposure is most likely in internet-facing or high-traffic Node.js services using hapi versions earlier than 11.1.3. The provided sources do not identify affected downstream products beyond the hapi node module.
Exploitation context
The source bundle does not show CISA KEV listing, public exploitation in the wild, or CVSS scoring. The described behavior is remotely reachable through HTTP headers, but no exploit procedure or observed campaign is cited.
Researcher notes
Evidence is sparse but consistent: older hapi mishandles certain date headers and retains sockets until timeout. The fixed boundary is 11.1.3. No CVSS, weaponized exploit evidence, or broader product matrix is provided in the supplied sources.
Mitigation direction
- Identify services using hapi versions earlier than 11.1.3.
- Upgrade hapi to 11.1.3 or later where applicable.
- Review vendor guidance and the upstream fix before deploying changes.
- Prioritize exposed services with high connection volume or limited worker capacity.
- Monitor for unusual socket timeouts and related header parsing errors.
Validation and detection
- Check dependency manifests and lockfiles for hapi versions below 11.1.3.
- Confirm running deployments match the remediated dependency version.
- Review logs for illegal access exceptions and elevated connection timeout patterns.
- Regression test HTTP caching header handling after upgrading.
- Validate service capacity and timeout metrics after remediation.
