Eclipse Threadx Netx Duo CVEs.

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.

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

Denial of service Server Eclipse Threadx Netx Duo

In NetX HTTP server functionality of Eclipse ThreadX NetX Duo before version 6.4.3, 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. This issue follows an incomplete fix of CVE-2025-0726.

In NextX Duo before 6.4.4, in the HTTP client module, the network support code for Eclipse Foundation ThreadX, the parsing of HTTP header fields was missing bounds verification. A crafted server response could cause undefined behavior.

Memory safety Library Eclipse Threadx Netx Duo

The security fix for CVE-2025-0728 in eclipse-threadx NetX Duo refactors error handling in the HTTP server PUT process to use a shared cleanup label, but this unified cleanup path unconditionally calls fx_file_close() even when the file was never successfully opened. Multiple error branches jump to the shared cleanup label before any file open operation has occurred, causing fx_file_close() to operate on an uninitialized file handle, leading to undefined behavior, double-close issues, or memory corruption.

A denial-of-service vulnerability exists in the NetX IPv6 component functionality of Eclipse ThreadX NetX Duo. A specially crafted network packet of "Packet Too Big" with more than 15 different source address can lead to denial of service. An attacker can send a malicious packet to trigger this vulnerability.

Denial of service Eclipse Threadx Netx Duo

In Eclipse Foundation NextX Duo before 6.4.4, a module of ThreadX, the _nx_secure_tls_process_clienthello() function was missing length verification of certain SSL/TLS client hello message: the ciphersuite length and compression method length. In case of an attacker-crafted message with values outside of the expected range, it could cause an out-of-bound read.
