4 October 2017
AusCERT Security Bulletin Summary
Product: Apache Tomcat
Operating System: UNIX variants (UNIX, Linux, OSX)
Impact/Access: Create Arbitrary Files -- Remote/Unauthenticated
CVE Names: CVE-2017-12617
Comment: This advisory references vulnerabilities in products which run on
platforms other than Apache. It is recommended that administrators
running Apache Tomcat check for an updated version of the software
for their operating system.
- --------------------------BEGIN INCLUDED TEXT--------------------
CVE-2017-12617 Apache Tomcat Remote Code Execution via JSP Upload
Vendor: The Apache Software Foundation
Apache Tomcat 9.0.0.M1 to 9.0.0
Apache Tomcat 8.5.0 to 8.5.22
Apache Tomcat 8.0.0.RC1 to 8.0.46
Apache Tomcat 7.0.0 to 7.0.81
When running with HTTP PUTs enabled (e.g. via setting the readonly
initialisation parameter of the Default servlet to false) it was
possible to upload a JSP file to the server via a specially crafted
request. This JSP could then be requested and any code it contained
would be executed by the server.
Users of the affected versions should apply one of the following
- - Upgrade to Apache Tomcat 9.0.1 or later
- - Upgrade to Apache Tomcat 8.5.23 or later
- - Upgrade to Apache Tomcat 8.0.47 or later
- - Upgrade to Apache Tomcat 7.0.82 or later
This issue was first reported publicly followed by multiple reports to
the Apache Tomcat Security Team.
