CVE-2025-2259Eclipse ThreadX NetX Duo component HTTP server single PUT request integer underflow

Descripción

In NetX 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 in one packet smaller than the data request size of the other packet. A possible workaround is to disable HTTP PUT support. This issue follows an incomplete fix of CVE-2025-0727
