CVE-2014-3285: Cisco Wide Area Application Services (WAAS) 5.3(.5a) and earlier, when SharePoint acceleration is enabled,...

Cisco Wide Area Application Services (WAAS) 5.3(.5a) and earlier, when SharePoint acceleration is enabled, does not properly parse SharePoint responses, which allows remote attackers to cause a denial of service (application-optimization handler reload) via a crafted SharePoint application, aka Bug ID CSCue47674.

Security readout for executives and security teams

This issue affects Cisco WAAS deployments running version 5.3(5a) or earlier when SharePoint acceleration is enabled. A malformed SharePoint response path can make the application-optimization handler reload, causing a partial denial of service. Business impact is service degradation for optimized SharePoint traffic, not documented data theft. Exposure is limited to Cisco WAAS 5.3(5a) and earlier with SharePoint acceleration enabled. Organizations without WAAS, without SharePoint acceleration, or on unaffected versions are not shown as exposed by the provided sources. Treat as a targeted availability risk for legacy Cisco WAAS environments. Prioritize verification if SharePoint performance or branch-office productivity depends on WAAS acceleration, but do not treat as confirmed ransomware-style exploitation from these sources. Mitigation focus: Check Cisco advisory and Bug ID CSCue47674 for supported fixes or workarounds.; Inventory Cisco WAAS versions and prioritize affected systems with SharePoint acceleration enabled.; Review whether SharePoint acceleration remains required until vendor-approved remediation is available..
