Summary

Eclipse ThreadX NetX Duo from 6.4.2 through 6.5.1.202602 has an uninitialized pointer flaw in its Web add-on HTTP server (CWE-824). When the server detects a Content-Length underflow while processing a PUT request, it dereferences and releases that uninitialized pointer. An unauthenticated remote client can trigger this with a single malformed request.

Description from the CNA

The Web add-on's HTTP server dereferences and releases an uninitialized pointer when it detects a `Content-Length` underflow while processing a `PUT` request. The condition is reachable by an unauthenticated remote client with a single malformed request.
