Summary: SQL injection in AVP Module
Initial Comment:
The AVPOPS module function avp_db_query is susceptable to SQL injection attacks
because any AVP's used within the query string are not escaped properly.
The UNIXODBC module has an existing sql escape function which could be used in
this case and it also has a module paramater to force escaping of paramaters
used in queries.
A simple script example of the problem is this:
avp_printf ("$avp(to_displayname)" ,"Mc'Dowell");
avp_db_query ("select * from table where a='$tn' and b=1")
On MySQL backend this will result in a SQL error on the query, but if the avp
var used comes from the wire a SQL injection is possible.

I've add a note about this behaviour to the function in the trunk and 1.2
branch.
It is possible, make it sense to escape all pv automatically in
avp_db_query?

This is a known limitation of the RAW queries. You have to escape the
parameters manually:

Probably we should add this to the avpops README.
