Security Bulletin
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 Temporal Score: See http://xforce.iss.net/xforce/xfdb/91625 for the current score
CVSS Environmental Score*: Undefined
CVSS Vector: (AV:N/AC:L/Au:N/C:N/I:N/A:P)
CVEID: CVE-2014-0075
DESCRPTION: 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 Environmental Score*: Undefined
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.
CVSS Base Score: 5
CVSS Temporal Score: See http://xforce.iss.net/xforce/xfdb/93369 for more information
