AI-suggested

A fixed version 6.5.2 of Eclipse ThreadX NetX Duo is available that addresses this vulnerability. Users should upgrade to version 6.5.2 or later to remediate the issue. No additional mitigations are specified by the vendor.

Description

Eclipse ThreadX NetX Duo versions 6.0 through 6.5.2.202603a use a cryptographically weak pseudo-random number generator (PRNG) for generating HelloVerifyRequest cookies in the DTLS server. The default NX_RAND() function relies on the standard C library rand() without a key or client binding. This weakness allows an attacker who can predict the PRNG output to spoof the cookie exchange and cause the server to send handshake data to a victim, effectively using the server as a traffic reflector.
