Hi! I am doing penetration test for client and have weird situation. Seems like I have SQL injection hole and I can command SQL server in "blind" injection. In some reason common technique ' or 'a'='a does not give right results but ' and 'a'='a does. Some examples: '+and'a'='a Normal screen '+and'a'='b Empty frame (means no result from SQL) '+and+exists+(select+1+from+sys.dual)+and'a'='a Generic error message. No reason explanation. Means that not Oracle. I also tried many other places like INFORMATION_SCHEMA to look up but no luck. '+and'a'||'a'='aa Also error. Again means not Oracle '+and'a'%2b'a'='aa This is weird. No error but no result either. Empty screen. Not MS SQL and many others. Why? '+and'0'%2b'0'='0 SQL gets proper result. '+and+concat('a','a')='aa Also works and provides result '+and+concat('a','a')='a emtpy screen '+and/*'*/+bar=bar+and+'a'='a Error message! Very weird because in my best knowledge every SQL knows about comments. '+and/**/+bar=bar+and+'a'='a Works. '+and/*!*/+bar=bar+and+'a'='a Error again. Any clue what is that SQL? As you see I can play with some syntaxes which belong to some language but it behaves wrong for common SQL engines. I know from headers that they use some XSLT middleware, Apache and ASP.NET. Probably few layers. Tõnu ------------------------------------------------------------------------------ This List Sponsored by: Cenzic Concerned about Web Application Security?
