# CVE-2025-2259

> 5.3 MEDIUM · 🧪 PoC

## Beschreibung

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
