Microsoft Windows Page File pagefile.sys Information Disclosure
Physical Access Required
Loss of Confidentiality
Windows contains a flaw that may lead to an unauthorized information disclosure. This flaw is due to the Windows paging file (Pagefile.sys) not being cleared when the system is shutdown. This flaw may present the sensitive information stored in memory in the paging file, including some plain passwords used by third-party program. This flaw may lead to a loss of confidentiality.
Currently, there are no known upgrades or patches to correct this issue. It is possible to correct the flaw by implementing the following workaround(s): Modify the registry to enable page file clearing.
1. Start Registry Editor.
2. Change the data value of the ClearPageFileAtShutdown value in the following registry key to a value of 1:
HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Control\Session Manager\ Memory Management
If the value does not exist, add the following value:
Value Name: ClearPageFileAtShutdown
Value Type: REG_DWORD
3. Restart your computer for the change to take effect
