Apache Tomcat is an open-source web server and servlet container that is widely used in enterprise environments to run Java web applications. However, like any web server, it is also vulnerable to various security threats. In this article, we’ll explore some of the most dangerous vulnerabilities in Tomcat and provide tips on how to protect your server from potential attacks.
- CVE-2020-1938 (Ghostcat) CVE-2020-1938, also known as Ghostcat, is a vulnerability that allows attackers to view sensitive information on Tomcat servers. This vulnerability can be exploited by sending a specially crafted request to the server, allowing an attacker to view files and directories that are not intended to be public. Ghostcat affects Tomcat versions 7.x, 8.x, 9.x, and 10.x.
To protect against Ghostcat, users should ensure that their Tomcat servers are up-to-date with the latest security patches. Additionally, users should limit access to sensitive files and directories, and implement network security measures such as firewalls and VPNs.
- CVE-2017-12617 (Apache Tomcat Remote Code Execution) CVE-2017-12617 is a remote code execution vulnerability that allows attackers to execute arbitrary code on Tomcat servers. This vulnerability can be exploited by sending a specially crafted request to the server, allowing an attacker to execute commands on the server as the user running the Tomcat process.
To protect against this vulnerability, users should ensure that their Tomcat servers are up-to-date with the latest security patches. Additionally, users should follow best practices such as restricting access to the Tomcat server to trusted networks and disabling unnecessary features and services.
- CVE-2020-9484 (Apache Tomcat RCE) CVE-2020-9484 is a remote code execution vulnerability that allows attackers to execute arbitrary code on Tomcat servers. This vulnerability can be exploited by sending a specially crafted request to the server, allowing an attacker to execute commands on the server with the permissions of the user running the Tomcat process.
To protect against this vulnerability, users should ensure that their Tomcat servers are up-to-date with the latest security patches. Additionally, users should restrict access to the Tomcat server to trusted networks, implement network security measures such as firewalls and VPNs, and limit the use of default or weak passwords.
Apache Tomcat is a popular web server and servlet container that is widely used in enterprise environments. However, it is also vulnerable to various security threats. To protect against these threats, users should ensure that their Tomcat servers are up-to-date with the latest security patches, follow best practices such as restricting access to the server and implementing network security measures, and stay informed about emerging threats and vulnerabilities. By taking these steps, users can help safeguard their Tomcat servers and prevent potential attacks.
