CVE-2025-2258 | THREATINT

Description

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.
