Title: Microsoft JET/ODBC Patch and RDS Fix Registry Key Vulnerabilities
Severity: MODERATE
Description:
Microsoft has made available fixes for the JET/ODBC and RDS vulnerabilities. These fixes implement specific Registry Key values to restrict "malicious activity". The Registry Keys include:
for JET/ODBC:
HKEY_LOCAL_MACHINE\Software\Microsoft\Jet\3.5\Engines\SandboxMode
for RDS:
HKEY_LOCAL_MACHINE\Software\Microsoft\DataFactory\HandlerInfo
Value: handlerRequired
DWORD=1
The Security Permissions over these Registry Keys are Set to "Everyone:Special Access". Special Access, in these instances, includes 'Set Value'. This permission allows members of the Everyone Group (Domain Users, Users, Guests, etc.) to modify the value of these keys, including the ability to disable the security features which may have been enabled by the administrator. Disabling the Data Factory\HandlerInfo setting ("handlerRequired DWORD=0") may open the host to exploit via the MDAC RDS exploit as described in Bugtraq ID 529 <http://www.securityfocus.com/bid/529.html>.
