Top 10 Most Critical CVEs Added in 2020

December 30, 2020

Our global community of hand-picked Detectify Crowdsource ethical hackers are the reason we are able to automate security research so quickly to protect web applications from attack. This past year, we received a record 1300+ submissions from the community including over 180 zero-day vulnerabilities. Every module and security test we build from these hacker-submitted vulnerabilities helps us make the internet more secure. As 2020 comes to a close, we’d like to thank all Crowdsourcers around the world for your hard work and contributions.

We might not be able to recognize everyone individually (we wish we could!) but here’s a list of the top 10 most critical CVEs in order of severity (maximum CVSS Base Score of 10) added to the Detectify scanner in 2020 – and the Crowdsourcers who made it possible!

1. CVE-2020-12720: vBulletin SQL Injection (OWASP 1: Injection)

vBulletin is a proprietary Internet forum software package used to build and manage online community websites. This module searches for a SQL injection vulnerability that would allow an attacker to launch a RCE attack via resetting the admin’s password.

OWASP Top 10: Injection
CVSS Base Score: 9.8

2. CVE-2020-5902: F5 BIG IP RCE and LFI (OWASP 1: Injection)

The Traffic Management User Interface on F5 BIG-IP is vulnerable to arbitrary command execution and local file read. A path normalization issue affects the Java backend, allowing an unauthenticated attacker to perform a relative path traversal attack and access sensitive endpoints that will grant further access within the system. On successful exploitation, an attacker will be able to execute arbitrary code on the system.

OWASP Top 10: Injection
CVSS Base Score: 9.8

3. CVE-2020-15506: MobileIron Core Authentication Bypass (OWASP 2: Broken Authentication)

An authentication bypass vulnerability exists in MobileIron Core and Connector versions 10.6 and earlier that allows remote attackers to bypass the authentication mechanism. This would allow attackers to access services and the admin panel.

OWASP Top 10: Broken Authentication
CVSS Base Score: 9.8

4. CVE-2020-14882: Oracle WebLogic RCE (OWASP 1: Injection)

Unpatched Oracle WebLogic servers allow attackers to execute arbitrary commands to download files, log keystrokes, steal sensitive data, and move laterally across a network. The vulnerability can be exploited by simply sending one request to the server.

OWASP Top 10: Injection
CVSS Base Score: 9.8
Crowdsourcer: @j3ssiejjj

5. CVE-2020-14750: Oracle WebLogic RCE (OWASP 1: Injection)

This is a Remote Code Execution (RCE) vulnerability in the Oracle WebLogic Server product of Oracle Fusion Middleware. If vulnerable, an attacker will be able to execute arbitrary commands on the application. Similar to CVE-2020-14882 above, the vulnerability can be exploited by simply sending one request to the server.

OWASP Top 10: Injection
CVSS Base Score: 9.8
Crowdsourcer: @madrobot

6. CVE-2020-17530: Apache Struts 2 RCE (OWASP 1: Injection)

Apache Struts (2.5.25 or earlier) is prone to a remote code execution vulnerability. In some cases, some tag attributes could perform a double OGNL evaluation on untrusted user input, which could lead to a remote code execution condition. An attacker would be able to execute system commands on the server.

OWASP Top 10: Injection
CVSS Base Score: 9.8
Crowdsourcer: @BBerastegui

7. CVE-2020-2551: Oracle WebLogic RCE (OWASP 1: Injection)

This is another vulnerability in the Oracle WebLogic Server product of Oracle Fusion Middleware affecting versions 10.3.6.0.0, 12.1.3.0.0, 12.2.1.3.0 and 12.2.1.4.0 that grants unauthenticated attackers with network access via IIOP to compromised Oracle WebLogic Servers.

OWASP Top 10: Injection
CVSS Base Score: 9.8
Crowdsourcer: @Corb3nik

8. CVE-2020-13379: Grafana SSRF (OWASP 3: Broken Access Control)

The avatar feature in Grafana contained a Server-Side Request Forgery (SSRF) vulnerability that permitted any unauthenticated user or client to make Grafana send HTTP requests to any URL and then return the result to the user or client.

OWASP Top 10: Broken Authentication
CVSS Base Score: 8.2
Crowdsourcer: @Rhynorater

9. CVE-2020-1147: Microsoft SharePoint Server RCE (OWASP 1: Injection)

This RCE vulnerability affects .NET Framework, Microsoft SharePoint, and Visual Studio when the software fails to check the source markup of XML file input. An attacker who successfully exploited the vulnerability could run arbitrary code in the context of the process responsible for deserialization of the XML content.

OWASP Top 10: Injection
CVSS Base Score: 7.8
Crowdsourcer: @geeknik

10. CVE-2020-8209: Citrix XenMobile Server Path Traversal (OWASP 3: Broken Access Control)

This is a path traversal vulnerability in Citrix XenMobile Server 10.12 before RP2, Citrix XenMobile Server 10.11 before RP4, Citrix XenMobile Server 10.10 before RP6, and Citrix XenMobile Server before 10.9 RP5. An attacker can download arbitrary files from the server and in some cases launch an RCE attack.

OWASP Top 10: Broken Authentication
CVSS Base Score: 7.5
Crowdsourcer: @j3ssiejjj

Honorable Mention: VMware vCenter Unauthenticated Arbitrary File (OWASP 3: Broken Access Control)

This last one was never assigned a CVE but is still noteworthy. VMware vCenter Server version 6.5.0 or earlier allows a remote attacker to arbitrarily read files on the host by accessing the open vCenter console. Attackers can read the vCenter configuration file to obtain the admin account password and then take over the vCenter platform and the virtual machine clusters it manages.
