medium Nessus Plugin ID 132074

Language:

Synopsis

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

Description

According to its self-reported version, Cisco IOS is affected by arbitrary memory write vulnerabilities in the embedded test subsystem due to the presence of certain test commands that were intended to be available only in internal development builds of the affected software. An authenticated, local attacker can exploit this, by using these commands on an affected device, to write arbitrary values to arbitrary locations in the memory space of an affected device.

Please see the included Cisco BIDs and Cisco Security Advisory for more information.

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

Solution

Upgrade to the relevant fixed version referenced in Cisco bug ID(s) CSCvc82464 and CSCuy10473.
