Description
This security bulletin contains information about 4 secuirty vulnerabilities.
1) Remote code execution (CVE-ID: CVE-2017-12615)
The vulnerability allows a remote attacker to execute arbitrary code on the target system.The weakness exists in Apache Tomcat when running on Windows with HTTP PUTs enabled (e.g. via setting the readonly initialisation parameter of the Default to false) due to input validation flaw. A remote attacker can send a specially crafted HTTP PUT request to upload an arbitrary JSP file to the target system and request the file to execute arbitrary code with privileges of the current user.
Successful exploitation of the vulnerability may result in system compromise.
2) Improper input validation (CVE-ID: CVE-2017-12617)
The vulnerability allows a remote attacker to execute arbitrary code on the target system.The weakness exists due to insufficient validation of user-supplied input when running with HTTP PUTs enabled. A remote attacker can send a specially crafted request to upload a JSP file to the server and execute arbitrary code on the system.
Successful exploitation of the vulnerability may result in full system compromise.
3) Information disclosure (CVE-ID: CVE-2017-5647)
The vulnerability allows a remote attacker to obtain potentially sensitive information on the target system.The weakness exists in the handling of the pipelined requests when send file was used resulted in the pipelined request being lost when send file processing of the previous request completed. A remote attacker can cause responses to appear to be sent for the wrong request.
4) Security bypass (CVE-ID: CVE-2017-5664)
The vulnerability allows a remote attacker to bypass security restrictions on the target system.The weakness exists due to improper handling of certain HTTP request methods for static error pages in Default Servlet. A remote attacker can bypass HTTP method restrictions and cause the error page to be deleted or replaced.
Successful exploitation of the vulnerability results in information modification.
