Memory leak in the intu-help-qb (aka Intuit Help System Async Pluggable Protocol) handlers in HelpAsyncPluggableProtocol.dll in Intuit QuickBooks 2009 through 2012, when Internet Explorer is used, allows remote attackers to cause a denial of service (memory consumption) via a URI with multiple references to the same name-value pair.

Security readout for executives and security teams

This is a legacy QuickBooks denial-of-service issue. A malicious web link opened in Internet Explorer could make the QuickBooks help protocol handler consume memory, potentially slowing or crashing the affected workstation. Exposure is mainly legacy Windows endpoints with QuickBooks 2009-2012 installed and Internet Explorer capable of invoking the Intuit help protocol handler. Treat as a legacy application risk, not an emergency. Prioritize if old QuickBooks remains on business-critical finance workstations or if Internet Explorer is still usable. Mitigation focus: Check Intuit and CERT guidance for supported remediation or workarounds.; Retire or upgrade QuickBooks 2009-2012 where still present.; Reduce Internet Explorer use on endpoints with affected QuickBooks versions..
