Vulnerability discussion

Packet Assembler Disassembler (PAD) is an X.25 component seldom used. It collects the data transmissions from the terminals and gathers them into a X.25 data stream and vice versa. PAD acts like a multiplexer for the terminals. If enabled, it can render the device open to attacks. Some voice vendors use PAD on internal routers.

Check content

Review the device configuration to determine if the PAD service is enabled. If the PAD service is enabled, this is a finding.

Fix text

Configure the device to disable the PAD service.
