Description
This security bulletin contains information about 4 secuirty vulnerabilities.
1) Heap memory exhaustion (CVE-ID: CVE-2017-12174)
The vulnerability allows a remote attacker to cause DoS condition on the target system.The weakness exists due to heap memory exhaustion. A remote attacker can trigger memory corruption and cause the service to crash.
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) Infinite loop (CVE-ID: CVE-2018-1041)
The vulnerability allows an adjacent attacker to cause DoS condition on the target system.The weakness exists due to an error when handling malicious input. An adjacent attacker can send specially crafted data to trigger an empty buffer read error in RemoteMessageChannel, consume excessive CPU resources and cause the application to enter an infinite loop and then the service to crash.
4) 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.
