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-2020-14181

Title: Atlassian Jira Server and Data Center User Enumeration Vulnerability

Vendor: Atlassian

Description: Atlassian Jira Server and Data Center allow an unauthenticated user to enumerate users via an Information Disclosure vulnerability in the /ViewUserHover.jspa endpoint.

CVSS v3 Base Score: 5.3 (AV:N/AC:L/PR:N/UI:N/S:U/C:L/I:N/A:N)


ID: CVE-2020-16938

Title: Microsoft Windows Kernel Information Disclosure Vulnerability

Vendor: Microsoft

Description: An information disclosure vulnerability exists when the Windows kernel improperly handles objects in memory. An attacker who successfully exploited this vulnerability could obtain information to further compromise the user's system. To exploit this vulnerability, an attacker would have to log on to an affected system and run a specially crafted application. The vulnerability would not allow an attacker to execute code or to elevate user rights directly, but it could be used to obtain information that could be used to try to further compromise the affected system.

CVSS v3 Base Score: 5.5 (AV:L/AC:L/PR:L/UI:N/S:U/C:H/I:N/A:N)


ID: CVE-2020-3118

Title: Cisco IOS XR Software Cisco Discovery Protocol Format String Vulnerability

Vendor: Cisco

Description: A vulnerability in the Cisco Discovery Protocol implementation for Cisco IOS XR Software could allow an unauthenticated, adjacent attacker to execute arbitrary code or cause a reload on an affected device. The vulnerability is due to improper validation of string input from certain fields in Cisco Discovery Protocol messages. An attacker could exploit this vulnerability by sending a malicious Cisco Discovery Protocol packet to an affected device.

CVSS v3 Base Score: 8.8 (AV:A/AC:L/PR:N/UI:N/S:U/C:H/I:H/A:H)


ID: CVE-2020-1472

Title: Microsoft Netlogon Elevation of Privilege Vulnerability

Vendor: Microsoft

Description: An elevation of privilege vulnerability exists when an attacker establishes a vulnerable Netlogon secure channel connection to a domain controller, using the Netlogon Remote Protocol (MS-NRPC). An attacker who successfully exploited the vulnerability could run a specially crafted application on a device on the network. To exploit the vulnerability, an unauthenticated attacker would be required to use MS-NRPC to connect to a domain controller to obtain domain administrator access.

CVSS v3 Base Score: 10.0 (AV:N/AC:L/PR:N/UI:N/S:C/C:H/I:H/A:H)


ID: CVE-2020-14882

Title: Oracle Weblogic Remote Code Execution Vulnerability

Vendor: Oracle

Description: A critical vulnerability exists in Oracle WebLogic Server product of Oracle Fusion Middleware (component: Console). Easily exploitable vulnerability allows unauthenticated attacker with network access via HTTP to compromise Oracle WebLogic Server. Successful attacks of this vulnerability can result in takeover of Oracle WebLogic Server.

CVSS v3 Base Score: 9.8 (AV:N/AC:L/PR:N/UI:N/S:U/C:H/I:H/A:H)


ID: CVE-2020-16898

Title: Microsoft Windows TCP/IP Stack Remote Code Execution Vulnerability

Vendor: Microsoft

Description: A remote code execution vulnerability exists when the Windows TCP/IP stack improperly handles ICMPv6 Router Advertisement packets. An attacker who successfully exploited this vulnerability could gain the ability to execute code on the target server or client. To exploit this vulnerability, an attacker would have to send specially crafted ICMPv6 Router Advertisement packets to a remote Windows computer.

CVSS v3 Base Score: 9.8 (AV:N/AC:L/PR:N/UI:N/S:U/C:H/I:H/A:H)


ID: CVE-2020-1013

Title: Microsoft Windows Group Policy Elevation of Privilege Vulnerability

Vendor: Microsoft

Description: An elevation of privilege vulnerability exists when Microsoft Windows processes group policy updates. An attacker who successfully exploited this vulnerability could potentially escalate permissions or perform additional privileged actions on the target machine. To exploit this vulnerability, an attacker would need to launch a man-in-the-middle (MiTM) attack against the traffic passing between a domain controller and the target machine. An attacker could then create a group policy to grant administrator rights to a standard user.

CVSS v3 Base Score: 8.1 (AV:N/AC:H/PR:N/UI:N/S:U/C:H/I:H/A:H)
