#
# The rule 942160 prevents time-based blind SQL injection attempts
# by prohibiting sleep() or benchmark(,) functions:
#
# * The sleep command takes a number of seconds as an argument.
# * The benchmark command executes the specified expression multiple times.
#
# Using a long sleep time or high number of executions, you can create a delay
# with the response from the server.  This allows to determine whether the
# query has been executed or not.  A high response time proves that the SQLi
# worked successfully. It can now be equipped with the real payload.
#
# Therefore this rule does not prevent the attack itself, but blocks an
# attacker from using the standard utils to tinker with blind SQLi.
#
# A positive side effect is that it prevents certain DoS attacks via the directives
# described above.

# -=[ Detect SQLi bypass: backticks ]=-
#
# Quotes and backticks can be used to bypass SQLi detection.
#
# Example:
# GET http://localhost/test.php?id=9999%20or+{`if`(2=(select+2+from+wp_users+where+user_login='admin'))}
#
# The minimum text between the ticks or backticks must be 2 (if, for example) and a maximum of 29.
# 29 is a compromise: The lower this number (29), the lower the probability of FP and the higher the probability of false negatives.
# In tests we got a minimum number of FP with {2,29}.
#
# Base64 encoding detection:
# (?:[A-Za-z0-9+/]{4})+ #match any number of 4-letter blocks of the base64 char set
# (?:[A-Za-z0-9+/]{2}== #match 2-letter block of the base64 char set followed by "==", together forming a 4-letter block
# |                     # or
# [A-Za-z0-9+/]{3}=     #match 3-letter block of the base64 char set followed by "=", together forming a 4-letter block
# )?
#
# The minimal string that triggers this regexp is: `if`
#
# The rule 942510 is related to 942110 which catches a single ' or `
#
# The rule 942511 is similar to this rule, but triggers on normal quotes
# ('if'). That rule runs in paranoia level 3 or higher since it is prone to
