TOP VULNERABILITY THIS WEEK: Latest Adobe Flash 0-day Flaw Active

Exploited in Nuclear, Neutrino, and Magnitude Exploit Kits


NOTABLE RECENT SECURITY ISSUES SELECTED BY THE TALOS SECURITY INTELLIGENCE AND RESEARCH GROUP

Title: Latest Adobe Flash 0-day Flaw Active Exploited in Nuclear,
Neutrino, and Magnitude Exploit Kits
Description: The most recent Flash zero-day vulnerability that was
disclosed and and patched by Adobe is currently being actively exploited
in three exploit kits. The Nuclear, Neutrino, and Magnitude exploit kits
have now incorporated exploits for CVE-2016-4117, targeting vulnerable
versions of Flash. As a reminder, users who do not require Flash are
strongly encouraged to remove it from their systems. For users who need
Flash and/or who do not have the ability to uninstall it, disabling
Flash within the browser is strongly recommended to reduce the risk of
compromise.

Title: Magneto Patches Several Security Flaws in Enterprise and
Community Editions
Description: Magneto has patched several security flaws in its flagship
eCommerce platform. The two most severe flaws addressed in the latest
patch are remote code execution vulnerabilities whereby an
unauthenticated attacker could either execute PHP code using REST or
SOAP APIs or forcefully reinstall the application. Magneto has addressed
these two critical flaws as well as four other vulnerabilities in its
latest version, 2.0.6. Administrators are strongly encouraged to updated
their Magneto installations to the latest version.
