Dr. Watson user.dmp Information Disclosure
Local Access Required Information Disclosure
Loss of Confidentiality
Exploit Public

- 漏洞描述

Dr. Watson contains a flaw that may lead to an unauthorized information disclosure. The issue is triggered when a malicious user with access rights to a shared computer accesses the user.dmp file created by Dr. Watson to obtain username and password information about other system users, resulting in a loss of confidentiality.

- 解决方案

Currently, there are no known upgrades or patches to correct this issue. It is possible to correct the flaw by implementing the following workaround: Run drwtsn32.exe to set crash dump options. There are two ways to get around this problem (per-user): 1) Uncheck the "create crash dump file" checkbox. -OR- 2) Change the crash dump location to a directory that only you have access to. For a system-wide fix, delete the registry key HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Windows NT\CurrentVersion\AeDebug\Debugger. This will cause Dr. Watson to be replaced with a simple "Application Error" box. If you have installed MSVC it will automatically make itself the system debugger, and it does not create crash dump files so you are not vulnerable.
