Summary

Eclipse ThreadX NetX Duo versions from 0 through 6.5.1.202602 are affected by CWE-444 in the Web add-on's HTTP server. The server searches the entire request packet for header fields instead of stopping at the end of the header section, so a header field name placed in the request body is treated as a real header. A remote attacker without privileges or user interaction can control request framing decisions, which affects integrity and availability.

Description from the CNA

The Web add-on's HTTP server searches the entire request packet for header fields instead of stopping at the end of the header section. A header field name placed in the request body is therefore reported to the server as though it were a header, which lets a client control request framing decisions it should not be able to reach.
