TOP VULNERABILITY THIS WEEK: Attacks against the version of Firefox

distributed in the Tor Browser Bundle were discovered in the wild this
week, with a payload that sent users’ MAC addresses to an IP address
presumed to be controlled by the federal government. The announcement
comes as a major blow to Tor, previously presumed to be the most secure
way to preserve anonymity on the Internet.


NOTABLE RECENT SECURITY ISSUES SELECTED BY THE SOURCEFIRE VULNERABILITY RESEARCH TEAM

Title: Firefox 17 bug exploited to de-anonymize Tor users
Description: A Javascript bug in Firefox version 17.0.7, the version
released as part of the Tor Browser Bundle, has been observed being
exploited in the wild with a payload that de-anonymizes the infected
user. Tracking information collected by this malware was then sent to a
hard-coded IP address in northern Virginia; speculation has run rampant
among the security community about the ultimate owner of the address,
with signs pointing towards the federal government. While a fix for the
bug enabling the attack is available, the issue highlights the
difficulty of ensuring anonymity on the Internet, even when using
supposedly secure services such as Tor.

Title: OpenX server packages backdoored since November 2012
Description: An announcement this week from the OpenX ad server team
noted that a backdoor had recently been discovered in their official
source code distributions, and that the backdoor has been present since
November 2012. While packages have since been cleaned, exploitation is
occurring in the wild, with attacks consisting of simple POST requests
to a specific file that allow for remote code execution on the infected
server. Users are urged to follow simple instructions being provided by
the community for checking their servers, and cleaning any that are
infected immediately.

Title: APT1/Comment Crew discovered breaking into a honeypot of a water plant
Description: A security researcher at Trend Micro detailed last week at
Black Hat how the now-notorious Chinese hacking group known alternately
as APT1 or the Comment Crew was discovered this past December breaking
into a decoy water plant, which they were able to gain complete control
over. The other attacks against industrial honeypots showed the ease
with which attackers can compromise such systems, and raises the very
real possibility that municipalities around the world are already
compromised by live attackers.

Title: Android weblogin shown to be vulnerable to trivial social
engineering attacks
Description: Researcher Craig Young of Tripwire demonstrated last week
at Defcon how Android applications which request permissions to
interface with the Google applications suite can take tokens which grant
access to one service, such as YouTube, and then use them throughout the
Google ecosystem, granting attackers the ability to change passwords,
alter domain services, access email and calendars, etc. While Google has
already made some fixes that require additional authentication beyond
weblogin tokens for sensitive operations, many issues remain;
additionally, the app used to demonstrate the problem was deployed
successfully on the Google Play store, demonstrating how easy it would
be for a malicious application to exploit this ecosystem weakness.

RECENT VULNERABILITIES FOR WHICH EXPLOITS ARE AVAILABLE COMPILED BY THE QUALYS VULNERABILITY RESEARCH TEAM

This is a list of recent vulnerabilities for which exploits are
available. System administrators can use this list to help in
prioritization of their remediation activities. The Qualys Vulnerability
Research Team compiles this information based on various exploit
frameworks, exploit databases, exploit kits and monitoring of internet
activity.

Description: Mozilla Firefox before 22.0, Firefox ESR 17.x before
17.0.7, Thunderbird before 17.0.7, and Thunderbird ESR 17.x before
17.0.7 do not properly handle onreadystatechange events in conjunction
with page reloading, which allows remote attackers to cause a denial of
service (application crash) or possibly execute arbitrary code via a
crafted web site that triggers an attempt to execute data at an unmapped
memory location.
CVSS v2 Base Score: 9.3 (AV:N/AC:M/Au:N/C:C/I:C/A:C)

ID: CVE-2011-0922
