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.

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-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

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
