Null Pointer Dereference in Stomper WebSocket Server

Executive Summary

This vulnerability occurs in Stomper when a client sends a SEND frame without a destination header. The server then tries to process this malformed frame, leading to a null pointer dereference or invalid memory access. This causes the server process to crash.

Detection Guidance

Detecting this vulnerability requires monitoring for crashes in the Stomper server when processing SEND frames without a destination header. Check server logs for null pointer dereference errors or segmentation faults during frame processing. Use network monitoring tools like tcpdump or Wireshark to capture and inspect SEND frames for missing destination headers.

Impact Analysis

If you use Stomper, an attacker could exploit this flaw by sending a specially crafted SEND frame without a destination header. This would crash the server, leading to a denial of service (DoS) and potentially disrupting services that rely on it.

Compliance Impact

This vulnerability causes a server crash due to a null pointer dereference when processing malformed SEND frames. It does not directly impact compliance with standards like GDPR or HIPAA as it is a denial-of-service issue rather than a data breach or privacy violation.

Mitigation Strategies

Update Stomper to a patched version that handles missing destination headers in SEND frames properly. If an update is unavailable, implement input validation to reject frames without the destination header before processing.
