I had to take the code a little further. I don't have mod_proxy/mod_rewrite installed, and I keep getting the following in the log files: 203.98.129.180 - - [05/Aug/2003:17:43:32 -0700] "POST http://64.59.128.220:25/ HTTP/1.1" 200 933 "-" "-" 203.98.129.180 - - [05/Aug/2003:17:43:32 -0700] "POST http://64.59.128.220:25/ HTTP/1.1" 200 933 "-" "-" System: apache 1.3.28, php 4.3.1, RH7.3 ======================================================== <?php if( strtoupper($_SERVER['REQUEST_METHOD'])=="CONNECT"){ header("HTTP/1.1 405 Method Not Allowed"); die(); } if( strtoupper($_SERVER['REQUEST_METHOD'])=="POST") { if (preg_match("/\:(\d+)/", $_SERVER['REQUEST_URI'], $matches)) { if (($matches[1] != '80') && ($matches[1] != '443')) { header("HTTP/1.1 405 Method Not Allowed"); die(); } } } ?> ======================================================== Previous Comments: ------------------------------------------------------------------------ [2003-07-07 17:59:18] jesseNO at SPAMhousejunkie dot ca I have also replicated this issue slack 9.0. 1.3.27 / 4.3.2 I have also applied the above fix <snip> <? if( strtoupper($_SERVER['REQUEST_METHOD'])=="CONNECT"){ header("HTTP/1.1 405 Method Not Allowed"); die(); } ?> </snip> I has stopped the issue until php releases the fix ------------------------------------------------------------------------ [2003-07-02 05:37:27] paul at pizza dot org Same problem Linux Mandrake 9.0 Apache 1.3.27 PHP 4.3.2. ------------------------------------------------------------------------ [2003-06-24 02:00:53] dortega at telenium dot es I've got the same problem with Solaris 2.8/Apache1.3.23/php-4.1.2 ------------------------------------------------------------------------ [2003-06-19 20:10:30] fallenmatt at yahoo dot com this is my temporally fix: i put it in an include file with a nice body (coppied from apache response to connect) and include it on top of index.php files for each virtual server: <? if( strtoupper($HTTP_SERVER_VARS['REQUEST_METHOD'])=="CONNECT"){ header("HTTP/1.1 405 Method Not Allowed"); die(); } ?> you should probably use $_SERVER[] instead... and no empty lines in your include file, otherwise header() gets confused ------------------------------------------------------------------------ [2003-06-19 09:47:51] fallenmatt at yahoo dot com i found this bug affecting my servers too. the severity of it is that spammers scan for open proxies and then don't check that they get smtp connection back, anything that's succesfull request puts the address on their proxy list. the result: i've got basically denial of service attack. My server was getting thousands of requests ("connect x.x.x.x:25) per hours, sometimes hundreds per minute. SInce it does a lot of mysql querries my database gaved up and started throwing can't connect to database errors. it is still a persistent problem. for a time being i check my counters and whenever i get large number of requests from same ip address i just ban it on my firewall. that is not a good sollution so still looking for a way to really fix it. ------------------------------------------------------------------------ The remainder of the comments for this report are too long.
