Title: Microsoft cryptography vulnerability lingers after Patch Tuesday

Description: The U.S. National Security Agency released a warning late last week, urging users to update their Microsoft products as soon as possible to fix a vulnerability in its cryptographic certificate-signing function. Attackers could use this bug to sign a program, and make it appear as if it is from a trusted source, without the user ever knowing about the adversary's actions. A security researcher was even able to create a proof of concept "Rick Rolling" the NSA's website to display a popular internet meme. The NSA's statement says that it believes "the vulnerability to be severe and that sophisticated cyber actors will understand the underlying flaw very quickly and, if exploited, would render the previously mentioned platforms as fundamentally vulnerable."

Title: Emotet continues to grow, spike in spam to start off 2020

Description: Emotet continues to infect individuals and organizations all over the world, but Cisco Talos recently discovered a new relationship between Emotet and the .mil (U.S. military) and .gov (U.S./state government) top-level domains (TLDs). When Emotet emerged from its summer vacation back in mid-September 2019, relatively few outbound emails were seen directed at the .mil and .gov TLDs. But sometime in the past few months, Emotet was able to successfully compromise one or more persons working for or with the U.S. government. As a result of this, Talos saw a rapid increase in the number of infectious Emotet messages directed at the .mil and .gov TLDs in December 2019.

Vulnerabilities with Exploits


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.


ID: CVE-2019-19781

Title: Citrix ADC And Citrix Gateway Arbitrary Code Execution Vulnerability

Vendor: Citrix

Description: A vulnerability has been identified in Citrix Application Delivery Controller (ADC) formerly known as NetScaler ADC and Citrix Gateway formerly known as NetScaler Gateway that, if exploited, could allow an unauthenticated attacker to perform arbitrary code execution. Successfully exploiting this issue will allow attackers to execute arbitrary code within the context of the application.

CVSS v2 Base Score: 7.5 (AV:N/AC:L/Au:N/C:P/I:P/A:P)


ID: CVE-2019-9730

Title: Synaptics Audio Driver Vulnerability

Vendor: Synaptics

Description: Incorrect access control in the CxUtilSvc.exe component of the Synaptics (previously Conexant) Audio driver could allow a standard user to increase access privileges to the Windows Registry via an unpublished API.

CVSS v2 Base Score: 7.2 (AV:L/AC:L/Au:N/C:C/I:C/A:C)


ID: CVE-2020-3941

Title: VMWare Privilege Escalation Vulnerability

Vendor: VMWare

Description: A vulnerability exists in VMware Tools for windows, which may allow for privilege escalation in the Virtual Machine where Tools is installed. A malicious actor on the guest VM might exploit the race condition and escalate their privileges on a Windows VM.

CVSS v2 Base Score: 7.2 (AV:L/AC:L/Au:N/C:C/I:C/A:C)


ID: CVE-2019-1547

Title: OpenSSL vulnerability

Vendor: Multi-Vendor

Description: In order to be vulnerable an attacker would have to have the ability to time the creation of a large number of signatures where explicit parameters with no co-factor present are in use by an application using libcrypto. For the avoidance of doubt libssl is not vulnerable because explicit parameters are never used. A local attacker can recover a full key during an ECDSA signature operation.

CVSS v2 Base Score: 1.9 (AV:L/AC:M/Au:N/C:P/I:N/A:N)
