Exposure of Sensitive Information to an Unauthorized Actor
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, might allow remote attackers to obtain sensitive information via a URI with a % (percent) character as its (1) last or (2) second-to-last character, in situations where a certain "post-URL data" buffer contains a 0x0000 character but a buffer overflow does not occur.
CWE-200 - Information Exposure
An information exposure vulnerability is categorized as an information flow (IF) weakness, which can potentially allow unauthorized access to otherwise classified information in the application, such as confidential personal information (demographics, financials, health records, etc.), business secrets, and the application's internal environment.
