# CVE-2025-2258

> 5.3 MEDIUM · 🧪 PoC

## Beschreibung

In NetX Duo component 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 smaller than the data request size. A
 possible workaround is to disable HTTP PUT support.




This issue follows an uncomplete fix in CVE-2025-0728.
