Synopsis

The remote device is affected by a memory disclosure vulnerability.

Description

According to its self-reported version number, the remote Juniper Junos QFX or EX series device is affected by a memory disclosure vulnerability, known as Etherleak, due to padding Ethernet packets with data from previous packets instead of padding them with null bytes. An unauthenticated, adjacent attacker can exploit this issue to disclose portions of system memory or data from previous packets. This issue is also often detected as CVE-2003-0001.

Note that Nessus has not tested for this issue but has instead relied only on the device's self-reported version and model
