Hello!
I have a SELECT comand passed trhough ASP like This:
SELECT PK_A_MSGID, C3_MSG, C3_MSGPT, C3_MSGEN FROM S_MSGS WHERE C3_MSG LIKE
""%Efectuar%"" ORDER BY PK_A_MSGID
and when i pass it it gives me:
SELECT PK_A_MSGID, C3_MSG, C3_MSGPT, C3_MSGEN FROM S_MSGS WHERE C3_MSG LIKE
"ïectuar" ORDER BY PK_A_MSGID
Why? how can i correct this?
Thanks 9 1300
I don't know what the story is with the %'s disappearing, but you should be
using ' to delimit in SQL, not ".
sSQL = "SELECT PK_A_MSGID, C3_MSG, C3_MSGPT, C3_MSGEN FROM S_MSGS WHERE
C3_MSG LIKE '%Efectuar%' ORDER BY PK_A_MSGID"

How about posting the relevant code snippet you're using to generate this
string?

Wouldnt the %E be converted to a character? In other words, it's
translating just like %20 becomes a space. %EF if some high order
character.
Try doing an encoding on the string before passing it.
Pass through the form collection instead of the querystring collection.
Aside from the string formatting issues, think about what the user could do
to this URL: http://www.yourserver.com/page.asp?q...T+*+FROM+table
Could easily become: http://www.yourserver.com/page.asp?q...OP+TABLE+table
Use ' not "" for delimiting the string, and consider passing only the
dynamic portion of the query...

Can someone please explain how changing to the form collection protects me
from this type of malicious submission? Assuming the user is sophisticated
enough to form a damaging request, I see no reason to think he could not
tweak a form submission with as much ease as a querystring.
Use ' not "" for delimiting the string, and consider passing only the dynamic portion of the query...
Consider? This should be a point of evangelism. If it's worth the time spent
to develop, it's worth a few minutes more to construct a stored procedure,
the benefits of which exceed simple prevention of malicious code execution.

It doesn't protect you, per se, but it makes it easier to validate (since
you can add referrer checks, session data, elapsed time, etc. to make sure
the form came from where you expect it to). This discussion thread is closed Replies have been disabled for this discussion. Similar topics
