CVE-2025-2259

Estado: AnalizadaMedia (5.3)—

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

CVSS
