YOU NEED TO ADD YOUR OWN ADDRESSES! Only applies to 2009M-2018

== '''LURE IS HOW YOU PATCH Signature Buffer Overflow!!!''' ==

== Explanation ==

* A buffer overflow is a memory vulnerability where custom or legacy engine code can be exploited by inputting more data than a buffer can handle. It's like a RCE but worse. That's why you need to patch this. To prevent this, you need to patch this.

== How it works ==

* '''CRoblox''': Detours <code>CRobloxApp::InitInstance</code> and <code>CRobloxCommandLineInfo::ParseParam</code> to allow authentication and join-script command line arguments.

* '''Context''': Adds verbose (or, at the very least, easier-to-understand) error messages for permission checks. '''This is only enabled when Lure is compiled as Debug.'''

* '''Crypt''': Adds SHA256 support for signature verification and patches a buffer overflow.

* '''Http''': Detours <code>Http::trustCheck</code> and <code>Http::httpGetPostWinInet</code>. Replaces the trustcheck with a custom check wherein you can include your own domains. Also redirects the <code>/asset</code>, <code>/Thumbs/Asset.ashx</code>, and <code>/Thumbs/Avatar.ashx</code> endpoints to their modern Roblox counterparts.

* '''ServerReplicator''': Enables ticket authentication by hooking <code>ServerReplicator::processTicket</code> and <code>ServerReplicator::sendTop</code>. Note that this has generally only been tested on 2011 releases.

* '''StandardOut''': Detours <code>StandardOut::print</code> to a console window. '''This is only enabled if Lure is compiled as Debug.'''

== Configuration ==

For finding subroutine addresses, x64dbg or IDA Pro is recommended.

{| class="wikitable"

!Name

!Expected value

|-

|<code>ALLOWED_WILDCARD_DOMAINS</code>

|Domains that are allowed no matter the subdomain; i.e. if <code>google.com</code> was whitelisted, <code>google.com</code>, <code>a.google.com</code>, and <code>a.b.google.com</code> would all be valid.

|-

|<code>ALLOWED_DOMAINS</code>

|Domains that are allowed only if the domain ''exactly'' matches; i.e. if <code>roblox.com</code> was whitelisted, <code>roblox.com</code> would be valid whereas <code>test.roblox.com</code> would not be.

|-

|<code>ALLOWED_SCHEMES</code>

|URL schemes that are allowed; <code>http</code>, <code>https</code>, etc. This is only for proper URLs.

|-

|<code>ALLOWED_EMBEDDED_SCHEMES</code>

|'''Don't modify this unless you know what you're doing!''' If a passed URI begins with this scheme, then the entire URL is valid; the data thereafter is irrelevant. This is only used for things like JavaScript and IE resources.

|-

|<code>PUBLIC_KEY</code>

|The Base64 encoded public key for signature verification. Default is the Roblox public key.

|}

Other preprocessor configuration is just addresses to subroutines. '''You may define <code>RESOLVE_OFFSETS</code> if the client obfuscates address locations on startup; Lure will find the addresses for you.'''

== Tutorial for building the DLL. ==

For this tutorial we will need to use vcpkg.

Copy this into git.<syntaxhighlight>

git clone https://github.com/lrre-foss/lure

</syntaxhighlight>Write the classes and all that.

Once you're done, open Visual Studio.

Then, select '''Open a local folder''' and open the place where GIT cloned Lure to.

Visual Studio will already detect Lure.sln and open vcpkg.

Set your build configuration type to debug.

Finally, build the dll.

== Tutorial for hooking the DLL. ==

* Copy the output DLL file to where you are keeping the Roblox executable (usually named <code>RobloxApp.exe</code>)

* Open the Roblox executable with StudPE (File -> Open PE File)

* Go to the '''Functions''' tab

* Right click in the left panel and click '''Add New Import'''.

* Click '''Dll Select''' and browse to <code>Lure.dll</code> in your Roblox folder

* Click '''Select func.''' and select <code>import</code> from the list that appears

* Click <code>Add to list</code>, then click <code>ADD</code> at the bottom

* Close the program by clicking <code>OK</code>. This will also save the patches to the executable file
