I found these in my error log today.  What do they mean and should I be worried?  Thanks in advance

As part of CubeCart's attempts to make sure nothing bad gets into your installation, the stuff in the querystring, the stuff that gets submitted in a form, the cookies, and a couple other things, gets looked at. Each of these has data in the form of a key/value pair (keyname=value).

CubeCart will only allow keynames through this security screen that have a very restricted set of letters . If the screen rejects a key, a mention is logged in the error log.

The keynames above have a slash in them, which is a character not in that restricted set of letters.

Unfortunately, the error log is not given what object the bad key was found in.

You may be able to correlate the time when the bad key was rejected with the time the access was made to your site in your web access logs. Then you can get a slightly better idea of who it was.

Logged errors do not cause problems. They are an indication of something else that might need looking into.

Its good to know that CubeCart is catching these. CC640 will trim away logged errors older than 7 days anyway, so delete them or not - it's up to you.
