Apache Tomcat Patches Important Security Vulnerabilities
Apache HTTP Server, colloquially called Apache is a free and open-source cross-platform web server, released under the terms of Apache License 2.0. Apache is developed and maintained by an open community of developers under the auspices of the Apache Software Foundation.
Apache Software Foundation (ASF) has released security updates to address several vulnerabilities in its Tomcat application server, one of which could allow a remote attacker to obtain sensitive information.
Apache Tomcat is an open source web server and servlet system, which uses several Java EE specifications like Java Servlet, JavaServer Pages (JSP), Expression Language, and WebSocket, and provides a “pure Java” HTTP web server environment for Java concept to run in.
Apache Tomcat — Information Disclosure Vulnerability
The more critical flaw (CVE-2018-8037) of all in Apache Tomcat is an information disclosure vulnerability caused due to a bug in the tracking of connection closures which can lead to reuse of user sessions in a new connection.
The vulnerability, marked as important, was reported to the Apache Tomcat Security Team by Dmitry Treskunov on 16 June 2018 and made public on 22 July 2018.
The flaw affects Tomcat versions 9.0.0.M9 to 9.0.9 and 8.5.5 to 8.5.31, and it has been fixed in Tomcat 9.0.10 and 8.5.32.
Apache Tomcat Server Software Updates (Patches)
The vulnerability affects Tomcat versions 7.0.x, 8.0.x, 8.5.x and 9.0.x, and has been addressed in Tomcat versions 9.0.7, 8.5.32, 8.0.52 and 7.0.90.
The Apache Software Foundation also included a security patch in the latest Tomcat versions to address a low severity security constraints bypass bug (CVE-2018-8034), which occurs due to missing of the hostname verification when using TLS with the WebSocket client.
Administrators are strongly recommended to apply the software updates as soon as possible and are advised to allow only trusted users to have network access as well as monitor affected systems.
The Apache Software Foundation says it has not detected any incident of the exploitation of one of these Apache Tomcat vulnerabilities in the wild.
A remote attacker could exploit one of these vulnerabilities to obtain sensitive information.
