The trigger is a four-byte handshake header and requires no cryptographic validity. It is reachable pre-authentication.
Default status is the baseline for the product, each version can override it (e.g. patched versions marked unaffected).

| Description | The TLS 1.3 Certificate-message parser in NetX Secure decrements the message length to skip a context byte without first establishing that the message has a byte to skip. A zero-length Certificate message therefore wraps the unsigned length to `0xFFFFFFFF`, which makes the bounds check that follows vacuous and sends the parser reading past the session packet buffer. The trigger is a four-byte handshake header and requires no cryptographic validity. It is reachable pre-authentication. | |
