Cisco Patches Critical VPN Vulnerability Affecting Adaptive Security Appliances

Ok, folks, this is a big one, so pay attention. It’s a remote code execution vulnerability and it received a CVSS base score of 10 (highest possible). If you use Cisco’s ASA software, you need to fix this vulnerability ASAP.

The vulnerability (CVE-2018-0101) affects various Adaptive Security Appliance (ASA) and Firepower Threat Defense Software products. It can be exploited remotely and does not require authentication. The proof of concept code available at the time of this writing creates a denial of service condition. However, we are expecting to see an exploit that allows the attacker to run arbitrary code any day now. Cisco initially released a patch in January to fix the flaw.  However, after learning of additional attack vectors, they released a second patch to fully remediate the vulnerability. We recommend applying the appropriate Cisco patches immediately.

Microsoft Addresses 50 Vulnerabilities in This Month’s Patch Tuesday

This month, Microsoft released patches to address 50 total vulnerabilities affecting Windows, Microsoft Office, Internet Explorer, Microsoft Edge, and the ChakraCore JavaScript engine. 14 of the vulnerabilities addressed were considered critical. Microsoft also included additional patches for the Meltdown and Spectre vulnerabilities in this month’s security updates. 

One particular nasty vulnerability (CVE-2018-0852) affects Outlook and should be prioritized for remediation. By sending a specially-crafted file to a user with an affected version of Outlook, an attacker could execute code in the context of the user when the victim views the email in the preview pane of Outlook. This one has “Internet worm” written all over it. We recommend you patch it as soon as possible.
