Security Bulletin: Vulnerabilities in Apache Tomcat affect the IBM FlashSystem model V840

Summary

There are vulnerabilities in Apache Tomcat to which the IBM® FlashSystem™ V840 is susceptible. An exploit of these vulnerabilities (CVE-2016-3092, CVE-2016-5385, CVE-5386, CVE-2016-5387, and CVE-2016-5388) could allow a remote attacker to wage a denial of service attack or redirect outbound HTTP traffic.

Vulnerability Details

CVEID: CVE-2016-3092 DESCRIPTION: Apache Tomcat is vulnerable to a denial of service, caused by an error in the Apache Commons FileUpload component. By sending file upload requests, an attacker could exploit this vulnerability to cause the server to become unresponsive.
CVSS Base Score: 5.3
CVSS Temporal Score: See https://exchange.xforce.ibmcloud.com/vulnerabilities/114336 for the current score
CVSS Environmental Score*: Undefined
CVSS Vector: (CVSS:3.0/AV:N/AC:L/PR:N/UI:N/S:U/C:N/I:N/A:L)

CVEID: CVE-2016-5385 DESCRIPTION: PHP could allow a remote attacker to redirect HTTP traffic of CGI application, caused by the failure to protect applications from the presence of untrusted client data in the HTTP_PROXY environment variable. By using a specially-crafted Proxy header in a HTTP request, an attacker could exploit this vulnerability to redirect outbound HTTP traffic to arbitrary proxy server. This is also known as the “HTTPOXY” vulnerability.
CVSS Base Score: 8.1

CVEID: CVE-2016-5386 DESCRIPTION: Google Go net/http package could allow a remote attacker to redirect HTTP traffic of CGI application, caused by the failure to protect applications from the presence of untrusted client data in the HTTP_PROXY environment variable. By using a specially-crafted Proxy header in a HTTP request, an attacker could exploit this vulnerability to redirect outbound HTTP traffic to arbitrary proxy server. This is also known as the “HTTPOXY” vulnerability.
