Summary

An issue was discovered in certain Apple products. iOS before 10.2.1 is affected. Safari before 10.0.3 is affected. tvOS before 10.1.1 is affected. The issue involves the "WebKit" component. It allows remote attackers to execute arbitrary code or cause a denial of service (memory corruption and application crash) via a crafted web site.

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.

    descriptionAccording to its banner, the version of Apple TV on the remote device is prior to 10.1.1. It is, therefore, affected by multiple vulnerabilities : - A stack-based buffer overflow condition exists in libarchive in the bsdtar_expand_char() function within file util.c due to improper validation of certain unspecified input. An unauthenticated, remote attacker can exploit this, via a specially crafted archive, to cause a denial of service condition or the execution of arbitrary code. (CVE-2016-8687) - A prototype access flaw exists in WebKit when handling exceptions. An unauthenticated, remote attacker can exploit this, via specially crafted web content, to disclose cross-origin data. (CVE-2017-2350) - A type confusion error exists in WebKit when handling SearchInputType objects due to improper validation of certain unspecified input. An unauthenticated, remote attacker can exploit this, via specially crafted web content, to execute arbitrary code. (CVE-2017-2354) - An unspecified memory initialization flaw exists in WebKit that allows an unauthenticated, remote attacker to execute arbitrary code via specially crafted web content. (CVE-2017-2355) - Multiple memory corruption issues exist in WebKit due to improper validation of certain unspecified input. An unauthenticated, remote attacker can exploit these, via specially crafted web content, to execute arbitrary code. (CVE-2017-2356, CVE-2017-2362, CVE-2017-2369, CVE-2017-2373) - A use-after-free error exists in the host_self_trap mach trap. A local attacker can exploit this, via a specially crafted application, to dereference already freed memory and thereby execute arbitrary code with kernel privileges. (CVE-2017-2360) - A flaw exists in WebKit when handling page loading due to improper validation of certain unspecified input. An unauthenticated, remote attacker can exploit this, via specially crafted web content, to disclose cross-origin data. (CVE-2017-2363) - A flaw exists in WebKit when handling variables due to improper validation of certain unspecified input. An unauthenticated, remote attacker can exploit this, via specially crafted web content, to disclose cross-origin data. (CVE-2017-2365) - A heap buffer overflow condition exists in the mach_voucher_extract_attr_recipe_trap() function due to improper validation of certain unspecified input. A local attacker can exploit this, via a specially crafted application, to cause a denial of service condition or the execution of arbitrary code with kernel privileges. (CVE-2017-2370) Note that only 4th generation models are affected by these vulnerabilities.

    support is disabled.

descriptionPoC: ``` <script> function go() { output.value = "aaa"; output.appendChild(inserted_div); document.getElementById("output").addEventListener('DOMSubtreeModified', function () { for(var i=0; i<20; i++) { form.appendChild(document.createElement("input")); } }, false); form.reset(); } </script> <body onload=go()> <div id="inserted_div">foo</div> <form id="form" onchange="eventhandler()"> <input type="text" value="foo"> <output id="output" oninput="eventhandler()"></output> <input type="text" value="foo"> ``` Analysis: The bug is in HTMLFormElement::reset() function, specifically in this part: for (auto& associatedElement : m_associatedElements) { if (is<HTMLFormControlElement>(*associatedElement)) downcast<HTMLFormControlElement>(*associatedElement).reset(); } The issue is that while m_associatedElements vector is being iterated, its content can change (HTMLFormControlElement being added or removed from it). Normally HTMLFormControlElement.reset() doesn't change the DOM, but there is one exception to this: The 'output' element. In WebKit, resetting the output element is equivalent to setting its textContent, which causes all of its child elements (if any) to be removed from the DOM tree. Using this trick we can remove elements from m_associatedElements while it is being iterated. However, this by itself is not sufficient to exploit this issue as m_associatedElements.remove(index) (called from HTMLFormElement::removeFormElement()) won't actually reallocate the vector's buffer, it will only decrease vector's m_size and the vector's elements after m_size will still point to the (former) form members. (It might be possible to force the removed form members to be deleted but I haven't experimented with this). So instead of removing elements from the m_associatedElements vector, I instead add elements to it while it is being iterated. I did this by adding DOMSubtreeModified event listener to the output element, so that when the output element gets reset, the event triggers and in the event hanlder newly created input elements are added to the form. This causes the vector's buffer to be reallocated to accommodate the new form elements. The loop inside HTMLFormElement::reset() continues to iterate over now deleted buffer, causing the use-after free condition. If an attacker manages to reclaim the space of the freed buffer and fill it with attacker-controlled data (there is plenty of opportunity to do this inside the DOMSubtreeModified event handler. Also note that the size of the freed buffer can be chosen by the attacker), subsequent iterations over m_associatedElements will cause HTMLFormControlElement::reset() method to be called on the attacker-controlled pointer. Since HTMLFormControlElement::reset() is a virtual function, this can easily lead to code execution.
