CVSS 7.5
Overview
In NetX Duo component HTTP server functionality of Eclipse ThreadX NetX Duo before
version 6.4.3, an attacker can cause an integer underflow and a
subsequent denial of service by writing a very large file, by specially
crafted packets with Content-Length smaller than the data request size. A
possible workaround is to disable HTTP PUT support.
This issue follows an uncomplete fix in CVE-2025-0728.
