TOP VULNERABILITY THIS WEEK: Active exploitation of last week’s Internet

Explorer 0-day is continuing in the wild this week, with live exploit
code beginning to appear on security research sites as of Tuesday. Since
the public availability of exploit code generally leads to mass
exploitation of broad-based vulnerabilities such as this one,
administrators should assume that exploit kits and the like will
incorporate the bug this week, and ensure that they have applied
Microsoft’s official FixIt while awaiting a full patch.


NOTABLE RECENT SECURITY ISSUES SELECTED BY THE SOURCEFIRE VULNERABILITY RESEARCH TEAM

Title: Attacks against Internet Explorer 0-day continuing in the wild
Description: Despite a major wave of publicity following the discovery
last week of a 0-day remote code execution flaw in Internet Explorer,
and the release of a workaround by Microsoft, in-the-wild exploitation
of the flaw (CVE-2013-3893) is continuing to take place, with security
vendor FireEye releasing an in-depth report about attacks occurring
specifically in Japan. Live exploit code began appearing on public
security research sites by Tuesday of this week, and worldwide
exploitation by exploit kits and other large-scale vectors is likely to
begin occurring well before the October 8 release of Microsoft’s
standard patch cycle. System administrators are urged to ensure that
Microsoft’s temporary fix has been applied immediately.

Title: Apple iPhone TouchID broken
Description: The Chaos Computer Club - one of the planet’s oldest
hacking organizations - was declared the official winner of a bounty
program that sprung up over the weekend to crack the new touch ID
authentication system in new iPhone 5 hardware, after the group
successfully lifted a print, replicated it with commonly available
technology, and gained access to a phone protected by the system. The
contest featured its share of hacker drama, after a pledge of $10,000
to the crowd-funded bounty was made by a venture capitalist who later
reneged on his promise, after having received considerable media
coverage for the pledge.

Title: Fake iMessage for Android surfaces, sends data to China
Description: An unofficial Apple iMessage client appeared in Google’s
Android market this week, with tens of thousands of downloads before
being pulled by Google. Several security researchers independently noted
that the application sent copies of all of the user’s data to an IP
address in China without any warning to the end user. While the
developer of the app insisted that the data being sent was for
legitimate purposes, the episode shows how easy it is for rogue apps to
harvest huge amounts of data from unsuspecting users even in relatively
well-policed markets such as Google Play.

Title: Java reflection attack allows remote code execution on Android < 4.2
Description: Security research firm MWR InfoSecurity released an
advisory this week detailing a reflection attack against the
addJavaScriptInterface functionality offered by the Android operating
system’s WebKit component, which allows developers to define methods
which can be called by JavaScript. Although the original intent of the
functionality was to expose only clearly defined methods, a trivial
sequence of calls could allow full command execution by malicious web
pages if any methods are exported at all through this interface. While
the issue has been fixed in Android 4.2, MWR’s research shows a wide
array of popular apps and ad networks still vulnerable to attacks.
