"Snagging Security Tokens to Elevate Privileges" is a brief that details how a database server running as a low privileged user on Windows can still provide an attacker with the ability to gain elevated privileges on the network and suggests a change in security policy to mitigate the risk. As a side note, this affects all network servers that offer OS based authentication - not just database servers.

Paper is based on a talk given earlier this year at Blackhat Europe. It divides SQL injection data theft attacks into three classes - inband, out-of-band and inference. The first, in-band, uses the existing connection to get data out; the second, out-of-band, uses another channel, e.g. smtp by using builtin database mail functions; and lastly inference.
