CVE-2026-93003— NetX Duo Web HTTP server interprets request body content as HTTP header fields
Quick assessment
Affected
Eclipse Foundation Eclipse ThreadX - NetX Duo
Exploitation
No confirmed in-the-wild exploitation; assess based on exposure
Recommended action
Check the vendor advisory and references for a fixed version. If immediate upgrade is impossible, restrict exposure and increase monitoring.
该 Web 扩展的 HTTP 服务器在解析请求时，会扫描整个请求包以查找头部字段，而不是在头部区域结束时停止。因此，若攻击者在请求体中放置一个头部字段名，服务器会将其误报为真正的请求头部，从而允许客户端操控本不应由其控制的请求分帧决策。

Vulnerability Title
NetX Duo Web HTTP server interprets request body content as HTTP header fields
Source: CVE Program / CVE List V5
Vulnerability Description
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.
