Technical ContextAI · show details

This vulnerability is classified as Unrestricted File Upload (CWE-434), which allows attackers to upload malicious files that can be executed on the server. When running Apache Tomcat 7.0.0 to 7.0.79 on Windows with HTTP PUTs enabled (e.g. via setting the readonly initialisation parameter of the Default 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. Affected products include: Apache Tomcat, Netapp 7-Mode Transition Tool, Netapp Oncommand Balance, Netapp Oncommand Shift, Redhat Enterprise Linux Server Update Services For Sap Solutions.
