I was browsing my error log today and noticed this error:
[Jul 12 11:36:50 2006] [error] [client 71.xxx.xxx.xx] mod_security: Warning. Pattern match "([0-9a-zA-Z]+[-._+&])*[0-9a-zA-Z]+@([-0-9a-zA-Z]+[.])+[a-zA-Z]{2,6}"
at POST_PAYLOAD [hostname "xxx.com"] [uri "/gallery/admin.php"]
Can anyone tell me what causes this? It occurs repeatedly thru out my error logs.
mod_security is telling you that someone from that IP made a POST request to admin.php that contained data matching that regular expression. Seems to be firing on the admin email address on that page. Probably nothing to worry about if that IP is yours. You'd need to ask whoever set it up what purpose that serves.
