CVE-2025-0727: Eclipse ThreadX NetX Duo HTTP server single PUT request integer underflow
First published: Fri Feb 21 2025(Updated: )
In NetX HTTP server functionality of Eclipse ThreadX NetX Duo before version 6.4.2, 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.
