Dear Brian Eaton, --Monday, May 21, 2007, 11:28:27 PM, you wrote to ascii () katamail com: BE> Given how few application platforms decode full-width unicode to ASCII BE> equivalents, is there a case to be made that those application BE> platforms that do decide this conversion is a good idea are broken? BE> Put another way: should this be considered a bug in ASP.NET? BE> Regards, BE> Brian Converting e.g. Unicode full-width 'A' into ASCII 'A' is definitely valid and expected behavior. A bug is using unfiltered input in HTML/SQL generation. As for inability of content filter to catch this situation, it's just one more way to bypass it. See http://securityvulns.com/advisories/content.asp http://securityvulns.com/advisories/bypassing.asp -- ~/ZARAZA http://securityvulns.com/ Итак, я буду краток.
