Netx Duo

In Eclipse ThreadX NetX Duo versions 6.0 through 6.5.2.202603, the NetX Secure DTLS server never compares the cookie a client returns with the one it issued, and treats any non-empty cookie as verified. A remote attacker can make the server send its full handshake flight, several kilobytes, to a forged source address, using it to reflect amplified traffic at a third party.

In Eclipse ThreadX NetX Duo versions up to and including 6.5.2.202603, the NetX Secure X.509 parser accepts a certificate whose signature is an empty BIT STRING and records a signature length of 0xFFFFFFFF. A remote peer can present such a certificate during the TLS handshake, before authentication, and make the device read far outside the certificate buffer during signature verification, which is expected to fault.

In Eclipse ThreadX NetX Duo versions up to and including 6.5.2.202603, built with IPv6, the ICMPv6 option validator accepts an option area that ends in a one- or two-byte residue, and the Router Advertisement, Neighbor Solicitation, Neighbor Advertisement and Redirect handlers then walk it without length checks. A host on the local link can send one such message to make the IP thread read past the packet or loop forever, and can place off-packet memory in the neighbor cache.

In Eclipse ThreadX NetX Duo versions up to and including 6.5.2.202603, the SNMP agent's OID parser uses a multi-byte BER length from the request without checking it against the bytes present, and reads past the end of the packet buffer. A remote, unauthenticated attacker can send a crafted SNMP request that makes the agent read adjacent memory into its OID state, faulting the agent on targets with memory protection.

In Eclipse ThreadX NetX Duo versions 6.4.0 through 6.5.2.202603a, built with VLAN and SRP support, the MSRP parser uses the attribute list length from the received frame without comparing it with the packet length. An unauthenticated station on the same Layer 2 segment can send a short MSRP frame declaring a long list and make the MRP worker read far past the received packet, faulting it on targets with memory protection.
