CVE-2025-0726 Details
Description
In NetX HTTP server functionality of Eclipse ThreadX NetX Duo before version 6.4.2, an attacker can cause a denial of service by specially crafted packets. The core issue is missing closing of a file in case of an error condition, resulting in the 404 error for each further file request. Users can work-around the issue by disabling the PUT request support.
A denial-of-service vulnerability has been identified in the HTTP server component of Eclipse ThreadX NetX Duo, in versions through 6.4.1. The issue arises when the server processes HTTP PUT requests. If an error occurs after a file is opened for writing, the file is not properly closed. This oversight leads to subsequent file requests being met with a 404 error. The vulnerability can be exploited by sending specially crafted packets that, for example, include a 'Content-Length' value larger than the actual data sent, causing a timeout error that is not handled correctly.
Users can upgrade to NetX Duo version 6.4.2 or later, or disable PUT request support in their application.
