Contiki-NG is an operating system for internet-of-things devices. In versions 4.9 and prior, when processing the various IPv6 header fields during IPHC header decompression, Contiki-NG confirms the received packet buffer contains enough data as needed for that field. But no similar check is done before decompressing the IPv6 address. Therefore, up to 16 bytes can be read out of bounds on the line with the statement `memcpy(&ipaddr->u8[16 - postcount], iphc_ptr, postcount);`. The value of `postcount` depends on the address compression used in the received packet and can be controlled by the attacker. As a result, an attacker can inject a packet that causes an out-of-bound read. As of time of publication, a patched version is not available. As a workaround, one can apply the changes in Contiki-NG pull request #2509 to patch the system.

According to its self-reported version number, the Kibana application running on the remote host is 7.x prior to 7.17.23 or 8.x prior to 8.14.0. It is, therefore, affected by a Denial Of Service by sending a large number of maliciously crafted requests to a specific endpoint.

Note that the scanner has not tested for these issues but has instead relied only on the application's self-reported version number.
