A thing like this is a big deal: WebEx has ~20 million users and many of them are enterprise and government users, or in other words, interesting targets for professional criminals and spies.\n\nAccording to Tavis, Cisco was impressively quick to issue an updated version 1.0.5 after receiving his report. The automatically installed update restricts the affected functionality so that it can only be used by web sites originating via HTTPS from domains webex.com and webex.com.cn.

Delivering the exploit from a fake local www.webex.com server didn't - as expected - show the above warning, but also didn't result in the exploit working. My theory is that Cisco also added some quick check to break this particular exploit, which was a smart thing to do, since cross-site scripting issues are surely about to start springing up on webex.com servers (one is already ",{"url":873,"meta":874,"type":12,"children":876},"https://twitter.com/mattaustin/status/824034201703878656/photo/1",[875],{"id":850,"value":851},[877],{"type":844,"value":878},"there",{"type":844,"value":880},").

Apparently WebEx developers have implemented the DLL white-listing strategy in version 1.0.5 that we mentioned in the original blog post, but Tavis has found a way around it by misusing the installation functionality for replacing one of the white-listed DLLs with Cisco-signed MSVCR100.DLL. Cisco has since published WebEx update 1.0.7 that fixes this bypass.]\n\nSo we have a publicly known remote code execution bug with a working POC on millions of computers, an unknown number of not-yet-updated WebEx extensions, an update that seems to be exploitable with cross-site scripting, and a still-secret residual remote code execution bug in the latest update.

The risk of resurrecting Tavis's exploit with some modification and cross-site scripting, or of simply tricking users to click OK, made me wonder if we could do a better fix with 0patch.\n\nMy initial thought was that we couldn't, as browser extensions are essentially JavaScript code and we currently can't patch that.

Surprisingly, it turned out that most of WebEx is actually native code - the browser code is merely in charge of launching ciscowebexstart.exe and passing the meeting parameters to it. It is this executable that then does the heavy lifting.\n\nTaviso's exploit shows that a WebEx message, which is used for launching a meeting, can also be used for executing any exported function with arbitrary arguments from any DLL in the WebEx folder. We don't know, perhaps even from anywhere on the computer or even from a remote network share.\n\nSo what if we patched WebEx so that it would only be possible to call a limited set of functions from a limited set of DLLs, namely those that are needed for WebEx's normal operations. Looking at what happens when a meeting is launched, my debugger and I could only find calls to functions from atmccli.DLL.Well, atmccli.DLL only exports four functions, and they all seem to be in use so why don't we simply limit loading of DLLs to atmccli.DLL?\n\nThe challenge at this point was to find the place in the code where the DLL name provided in the (potentially malicious) WebEx message is used for actually loading a DLL, likely using LoadLibrary/Ex. If we found that place, we could perhaps replace the DLL name with \"atmccli.DLL\".\n\nI started by monitoring ciscowebexstart.exe with Process Monitor to see the call stack where Tavis's calc.exe gets launched. This is what I found.\n\n",{"item":810,"type":867},{"type":841,"children":934},[935,937,941],{"type":844,"value":936},"\n\n\n\nApparently, it is atgpcext.dll that calls wsystem from MSVCR100.DLL. So I opened it up in IDA and looked around the addresses in the above call stack. Fortunately, a lot of logging strings are sprinkled around the DLL, making it easier to understand what the code is supposed to be doing.\n\nSubsequent hours comprised of typical connect-the-dots reversing steps, switching from IDA to WinDbg to Process Monitor and back in attempting to understand the process from point A (web site sending WebEx a message) to point B (the chosen DLL function gets invoked).\n\nEventually the dots were connected and I ended up with a decent patch candidate:\n\n\n",{"type":844,"marks":938,"value":940},[939],"code","MODULE_PATH \"C:\\ProgramData\\WebEx\\WebEx\\T30_MC\\atgpcext.dll\"\nPATCH_ID 10000\nPATCH_FORMAT_VER 2\nVULN_ID 2099\nPLATFORM win32\n\npatchlet_start\nPATCHLET_ID 1\nPATCHLET_TYPE 2\n\nPATCHLET_OFFSET 0x5da9f\nJUMPOVERBYTES 5 ; We jump over the original \"call sub_21CBA\"\nN_ORIGINALBYTES 5\n\ncode_start\n\n    call over\n    dw __utf16__(\"atmccli.dll\"),0\nover:\n    pop eax\n\ncode_end\npatchlet_end",{"type":844,"value":942},"\n\nLet's see what this patch does. It gets applied to WebEx's atgpcext.dll at offset 0x5da9f, and replaces the call to function which returns a pointer to the DLL name from the message with a pointer to our own fixed string, \"atmccli.dll\". This replacing is caused by JUMPOVERBYTES 5, which tells 0patch agent not to continue execution of the original code after returning from the patch code, but to jump over (well, obviously) 5 bytes of that code, effectively landing just behind the \"call sub_21CBA\" 5-byte instruction.\n\nBut wait, what is this trickery in the patch code? Do we really make a call to some label, then pop eax from the stack? Yes we do. This is an efficient, and very hacker-worthy solution for getting a pointer to a string if you don't have some extra space to store said string. The call namely pushes the address of the \"following instruction\" to stack, but what follows is not an instruction but the string. The pop then takes the address of the string from stack, and that's all the patch needs to do. (Note that this is an old trick; if you have any references to its past use, do let me know so I can credit the author.)\n\nNow, the result of this patch getting applied is that whichever DLL one instructs WebEx to use, WebEx will always use its own atmccli.DLL. This obviously breaks Tavis's exploit, as he is trying to load MSVCR100.DLL, and we replace that with atmccli.DLL; there is no _wsystem exported function in atmccli.DLL, so the operation silently fails.\n\nLet's take a look at a video showing how this micropatch blocks the exploit while keeping WebEx functional.\n\n",{"item":824,"type":867},{"type":841,"children":945},[946,949],{"type":844,"marks":947,"value":948},[910],"So How Good Is This Micropatch?",{"type":844,"value":950},"\n\nGenerally speaking, there can be two problems with a security patch: it can fail to adequately remove the security issue, and/or it can cause functional problems.\n\n",{"type":952,"style":953,"children":954},"list","numbered",[955,982],{"type":956,"children":957},"listItem",[958],{"type":841,"children":959},[960,963,965,971,973,980],{"type":844,"marks":961,"value":962},[910],"Adequate removal of the security issue",{"type":844,"value":964},": Frankly, it's hard to say without digging deep into what the four exported functions of atmccli.DLL are capable of.
