Security Bulletin


Summary

IBM QRadar Security Information and Event Manager (SIEM) 7.1 MR2 and 7.2 MR2 utilizes Apache Tomcat versions that contain multiple vulnerabilities.

Vulnerability Details

CVE ID:
CVE-2013-4286

DESCRIPTION:
Apache Tomcat is vulnerable to HTTP request smuggling, caused by an incomplete fix related to the handling of malicious requests. 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:
CVSS Base Score: 4.3
CVSS Temporal Score: See https://exchange.xforce.ibmcloud.com/vulnerabilities/91426 for the current score
CVSS Environmental Score*: Undefined
CVSS Vector: (AV:N/AC:M/Au:N/C:N/I:P/A:N)


CVE ID:
CVE-2014-0033

DESCRIPTION:
Apache Tomcat could allow a remote attacker to hijack a valid user's session, caused by an error even when disableURLRewriting is enabled. By persuading a victim to visit a specially-crafted link and log into the application, a remote attacker could exploit this vulnerability to hijack another user's account and possibly launch further attacks on the system.

CVSS:
CVSS Base Score: 4.3
CVSS Temporal Score: See https://exchange.xforce.ibmcloud.com/vulnerabilities/91423 for the current score
CVSS Environmental Score*: Undefined
CVSS Vector: (AV:N/AC:M/Au:N/C:N/I:P/A:N)


CVE ID:
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:
CVSS Base Score: 5
CVSS Temporal Score: See https://exchange.xforce.ibmcloud.com/vulnerabilities/91625 for the current score
CVSS Environmental Score*: Undefined
CVSS Vector: (AV:N/AC:L/Au:N/C:N/I:N/A:P)


CVE ID:
CVE-2013-4590

DESCRIPTION:
Apache Tomcat could allow a remote attacker to obtain sensitive information, caused by an XML External Entity Injection (XXE) error when running untrusted
web applications. By sending a specially-crafted request, an attacker could exploit this vulnerability to read arbitrary files and obtain sensitive information.

CVSS:
CVSS Base Score: 4.3

Disclaimer

According to the Forum of Incident Response and Security Teams (FIRST), the Common Vulnerability Scoring System (CVSS) is an "industry open standard designed to convey vulnerability severity and help to determine urgency and priority of response." IBM PROVIDES THE CVSS SCORES ""AS IS"" WITHOUT WARRANTY OF ANY KIND, INCLUDING THE IMPLIED WARRANTIES OF MERCHANTABILITY AND FITNESS FOR A PARTICULAR PURPOSE. CUSTOMERS ARE RESPONSIBLE FOR ASSESSING THE IMPACT OF ANY ACTUAL OR POTENTIAL SECURITY VULNERABILITY. In addition to other efforts to address potential vulnerabilities, IBM periodically updates the record of components contained in our product offerings. As part of that effort, if IBM identifies previously unidentified packages in a product/service inventory, we address relevant vulnerabilities regardless of CVE date. Inclusion of an older CVEID does not demonstrate that the referenced product has been used by IBM since that date, nor that IBM was aware of a vulnerability as of that date. We are making clients aware of relevant vulnerabilities as we become aware of them. "Affected Products and Versions" referenced in IBM Security Bulletins are intended to be only products and versions that are supported by IBM and have not passed their end-of-support or warranty date. Thus, failure to reference unsupported or extended-support products and versions in this Security Bulletin does not constitute a determination by IBM that they are unaffected by the vulnerability. Reference to one or more unsupported versions in this Security Bulletin shall not create an obligation for IBM to provide fixes for any unsupported or extended-support products or versions.
