|
|
This module can be used to execute arbitrary code on IIS servers
|
|
that expose the /msadc/msadcs.dll Microsoft Data Access Components
|
|
(MDAC) Remote Data Service (RDS) DataFactory service. The service is
|
|
exploitable even when RDS is configured to deny remote connections
|
|
(handsafe.reg). The service is vulnerable to a heap overflow where
|
|
the RDS DataStub 'Content-Type' string is overly long. Microsoft Data
|
|
Access Components (MDAC) 2.1 through 2.6 are known to be vulnerable.
