Description
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
