Cisco StarOS DoS (cisco-sa-StarOS-DoS-RLLvGFJj)

high Nessus Plugin ID 150073

Synopsis

The remote device is missing a vendor-supplied security patch

Description

According to its self-reported version, the SSH service of the Cisco StarOS operating system is affected by denial of service vulnerability due to a logic error that may occur under specific traffic conditions. An unauthenticated, remote attacker could exploit this by sending a series of crafted packets to an affected device. A successful exploit could allow the attacker to prevent the targeted service from receiving any traffic, which would lead to a DoS condition on the affected device.

Please see the included Cisco BID 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 CSCvu59686
