CVE-2025-2259
Good to know:
Date: April 6, 2025
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
