CVE-2025-0727 describes an integer underflow vulnerability in the NetX HTTP server functionality of Eclipse ThreadX NetX Duo before version 6.4.2. An unauthenticated attacker can trigger a denial of service by sending specially crafted HTTP packets that manipulate Content-Length values, potentially by writing a very large file. This vulnerability carries a CVSS score of 7.5 (HIGH), indicating a network-based attack with low complexity and high impact on availability. While no active exploitation, public exploit code, or significant community discussion has been observed, disabling HTTP PUT support is a possible workaround.
