My wordpress logs show 404 errors to URLs having the following pattern:
http://example.com/path/++GET+http:/example/+0,48595,73506+-
Web searches do not return answers because of the plus and minus symbols. Note that the second http is followed by a single slash. Accessing my site with a corrected URL (where I use a double slash after the second http) returns a 404.
My logs show fifty errors each day from different IP addresses, where each IP address tries the same file three times.
I am curious to know what type of exploit this may be. It seems to have something to do with the GET request method.
Ideas?
