TITLE

Cisco Wide Area Application Service and Virtual WAAS Run on device CIFS Service disruption in optimization function (DoS) Vulnerabilities

Trust: 0.8

sources: JVNDB: JVNDB-2015-006859

DESCRIPTION

cifs-ao in the CIFS optimization functionality on Cisco Wide Area Application Service (WAAS) and Virtual WAAS (vWAAS) devices 5.x before 5.3.5d and 5.4 and 5.5 before 5.5.3 allows remote attackers to cause a denial of service (resource consumption and device reload) via crafted network traffic, aka Bug ID CSCus85330. Cisco Wide Area Application Services is prone to a remote denial-of-service vulnerability. An attacker can exploit this issue to reload the affected device, denying service to legitimate users. This issue is being tracked by Cisco Bug ID CSCus85330. WAAS is a set of WAN link acceleration software. This software is mainly used in the link environment with small bandwidth and large delay. vWAAS is a cloud-based WAN optimization solution. The solution supports the use of policy-based on-demand business processes to accelerate private and virtual private cloud infrastructure and application delivery. There is a security vulnerability in cifs-ao in the CIFS optimization feature of Cisco WAAS and vWAAS. The following products and versions are affected: Cisco WAAS and vWAAS 5.3.5d prior to 5.x releases, 5.4 releases, 5.5.3 prior to 5.5 releases
