Cisco IOS Software TCP CIP DoS

high Nessus Plugin ID 82571

Language:

Synopsis

The remote device is missing a vendor-supplied security patch.

Description

According to its self-reported version, the Cisco IOS software running on the remote device is affected by multiple flaws in the Common Industrial Protocol (CIP) implementation that allow a remote, unauthenticated attacker to cause a denial of service (DoS) condition, as follows:

- A denial of service (device reload) may be triggered via malformed CIP UDP packets. (CVE-2015-0647)

- A denial of service (memory consumption) may be triggered via crafted CIP TCP packets. (CVE-2015-0648)

- A denial of service (device reload) may be triggered via malformed CIP TCP packets. (CVE-2015-0640)

Note that Nessus has not tested for this issue but has instead relied only on the application's self-reported version number.

Solution

Apply the relevant patch referenced in the vendor advisory.
