NOTABLE RECENT SECURITY ISSUES
SELECTED BY THE TALOS SECURITY INTELLIGENCE AND RESEARCH GROUP
Title: Microsoft Patch Tuesday includes 25 critical vulnerabilities
Description: Microsoft released its monthly security update today, disclosing vulnerabilities across many of its products and releasing corresponding updates. This month's Patch Tuesday covers 117 vulnerabilities, 25 of which are considered critical. There is also one moderate vulnerability and 91 that are considered important. This month's patches include updates to Microsoft Media Foundation, the GDI+ API and Windows Defender, among others.

Snort SIDs: 52213, 52214, 53402 - 53409, 53414 - 53419, 53420 - 53424
Title: State-sponsored groups exploit bug in Microsoft Exchange servers
Description: The U.S. Department of Defense warned that multiple state-sponsored actors are exploiting a vulnerability in Microsoft Exchange servers. The bug was disclosed and patched in February, but many users out there have not updated their software. Attackers can send malicious, specially crafted requests to the Exchange control panel. The vulnerability allows adversaries to change serialized data to be unserialized, which allows them to run malicious code on the server's backend at the system level.

Several security-related conferences are either postponing or canceling their events due to concerns over the COVID-19 disease, including Kaspersky's SAS and Black Hat Asia.
Newly released documents and reports paint a broader picture of why a deal between the U.S. government and an influential Swiss cyber security company fell apart in the 1950s.
Nearly all Intel CPUs and chipsets made over the past five years contain an unfixable security flaw that could allow attackers to execute malicious code on victim machines with the highest possible level of credentials.
A vulnerability in Apple's iOS and MacOS' kernels could allow adversaries to use the AirDrop feature to remotely dump physical memory, without requiring any user interaction. The bug has been patched since it was disclosed by Google's Project Zero.
https://bugs.chromium.org/p/project-zero/issues/detail?id=1982
New research from an antivirus testing firm discovered that the detection software on the Google Play store is not at effective as defending against malicious apps as advertised.
Members of the U.S. Senate were scheduled to be briefed on election security Tuesday afternoon, though the acting director of national intelligence was not expected to be in attendance.
The FBI arrested a man they believe is behind the website deer.io, a popular site for adversaries to buy and sell stolen user credentials for online stores and services.

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.
ID: CVE-2020-0688
Title: Microsoft Windows Installer Elevation of Privilege Vulnerability
Vendor: Microsoft
Description: An elevation of privilege vulnerability exists in the Windows Installer when MSI packages process symbolic links. An attacker who successfully exploited this vulnerability could bypass access restrictions to add or remove files.
CVSS v3 Base Score: 7.8 (AV:L/AC:L/PR:L/UI:N/S:U/C:H/I:H/A:H)
ID: CVE-2020-8597
Title: pppd EAP Processing Buffer Overflow Vulnerability ("Ghostcat")
Vendor: Multi-Vendor
Description: pppd (Point to Point Protocol Daemon) is vulnerable to buffer overflow due to a flaw in Extensible Authentication Protocol (EAP) packet processing in eap_request and eap_response subroutines. The vulnerability is in the logic of the eap parsing code. By sending an unsolicited EAP packet to a vulnerable ppp client or server, an unauthenticated remote attacker could cause memory corruption in the pppd process, which may allow for arbitrary code execution.
CVSS v3 Base Score: 9.8 (AV:N/AC:L/PR:N/UI:N/S:U/C:H/I:H/A:H)
ID: CVE-2019-0090
Title: Intel CSME Privilige Escalation Vulnerability
Vendor: Intel
Description: Insufficient access control vulnerability exists in subsystem for Intel(R) CSME that may allow an unauthenticated user to potentially enable escalation of privilege via physical access.
CVSS v3 Base Score: 7.1 (AV:P/AC:H/PR:N/UI:N/S:C/C:H/I:H/A:H)
ID: CVE-2020-9334
Title: WordPress Envira Photo Gallery plugin Stored XSS Vulnerability
Vendor: WordPress
Description: A stored cross site scripting vulnerability exists in the Envira Photo Gallery plugin for WordPress. Successful exploitation of this vulnerability would allow a authenticated low privileged user to inject arbitrary JavaScript code that is viewed by other users.
CVSS v3 Base Score: 5.4 (AV:N/AC:L/PR:L/UI:R/S:C/C:L/I:L/A:N)
ID: CVE-2020-10189
Title: WPA and WPA2 Disassociation Vulnerability ("Kr00k")
Vendor: Multi-Vendor
Description: An issue was discovered on Broadcom Wi-Fi client devices. Specifically timed and handcrafted traffic can cause internal errors (related to state transitions) in a WLAN device that lead to improper layer 2 Wi-Fi encryption with a consequent possibility of information disclosure over the air for a discrete set of traffic.
CVSS v3 Base Score: 3.1 (AV:A/AC:H/PR:N/UI:N/S:U/C:L/I:N/A:N)
ID: CVE-2019-1458
Title: Microsoft Win32k Elevation of Privilege Vulnerability
Vendor: Microsoft
Description: An elevation of privilege vulnerability exists in Windows when the Win32k component fails to properly handle objects in memory. An attacker could then run a specially crafted application that could exploit the vulnerability and take control of an affected system.
CVSS v3 Base Score: 7.8 (AV:L/AC:L/PR:L/UI:N/S:U/C:H/I:H/A:H)
ID: CVE-2020-1938
Title: Apache Tomcat AJP File Inclusion Vulnerability ("Ghostcat")
Vendor: Apache
Description: Due to a file inclusion defect in the AJP service (port 8009) that is enabled by default in Tomcat, an attacker can construct a malicious request package for file inclusion operation, and then read the web directory file on the affected Tomcat server.
CVSS v3 Base Score: 9.8 (AV:N/AC:L/PR:N/UI:N/S:U/C:H/I:H/A:H)
