Security Bulletin: Apache Tomcat vulnerabilities on IBM System Storage Storwize V7000 Unified (CVE-2013-4286 CVE-2013-4332 CVE-2014-0075 CVE-2014-0099)

Summary

Apache Tomcat DoS and unauthorized access vulnerabilities

Vulnerability Details

This bulletin relates to vulnerabilities in the Apache Tomcat component which is used to provide the product’s management GUI. The CLI interface is unaffected.

CVEID:CVE-2013-4286

**DESCRIPTION:**Apache Tomcat is vulnerable to HTTP request smuggling, caused by an incomplete fix related to the handling of malicious request. By sending a specially-crafted request in a Transfer-Encoding: chunked header and a Content-length header to the Apache HTTP server that will be reassembled with the original Content-Length header value, an attacker could exploit this vulnerability to poison the web cache, bypass web application firewall protection, and conduct XSS attacks.

CVSS Base Score: 4.3
CVSS Temporal Score: See http://xforce.iss.net/xforce/xfdb/91426 for more information
CVSS Environmental Score*: Undefined
CVSS Vector: (AV:N/AC:M/Au:N/C:N/I:P/A:N)

CVEID:CVE-2013-4322

**DESCRIPTION:**Apache Tomcat is vulnerable to a denial of service, caused by an incomplete fix related to the processing of chunked transfer coding without properly handling a large total amount of chunked data or whitespace characters in an HTTP header value. A remote attacker could exploit this vulnerability to cause a denial of service.

CVSS Base Score: 5

CVSS Vector: (AV:N/AC:L/Au:N/C:N/I:N/A:P)

CVEID:CVE-2014-0075

**DESCRIPTION:**Apache Tomcat is vulnerable to a denial of service, caused by the improper handling of a malformed chunk size as part of a chucked request. A remote attacker could exploit this vulnerability to cause a denial of service.

CVSS Base Score: 5
CVSS Temporal Score: See http://xforce.iss.net/xforce/xfdb/93365 for more information

CVSS Vector: (AV:N/AC:L/Au:N/C:N/I:N/A:P)

CVEID:CVE-2014-0099

**DESCRIPTION:**Apache Tomcat could allow a remote attacker to obtain sensitive information, caused by the failure to check for overflows when parsing content length headers. By sending specially-crafted request, an attacker could exploit this vulnerability to obtain sensitive information.
