Summary
This bulletin relates to several security vulnerabilities that have been
reported against Apache Struts through May 2014. IBM Connections uses a
version of Struts that is vulnerable to these issues.
Vulnerability Details
Several security vulnerabilities have been reported against Apache Struts
through April 2014. IBM Connections uses Struts. A version of the package
that is vulnerable to these issues is used in several past versions of IBM
Connections. To fix these vulnerabilities apply the fixes as detailed in
the Remediation section.
CVE-ID: CVE-2014-0116
Description: Apache Struts could allow a remote attacker to bypass security
restrictions, caused by the failure to properly restrict access to the
getClass() method by the CookieInterceptor class. An attacker could exploit
this vulnerability to manipulate the ClassLoader used by the application
server.
CVSS Base Score: 4.3
CVSS Temporal Score: See http://xforce.iss.net/xforce/93024 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-2014-0114
Description: Apache Struts could allow a remote attacker to execute arbitrary
code on the system, caused by the failure to restrict the setting of Class
Loader attributes. An attacker could exploit this vulnerability using the
class parameter of an ActionForm object to manipulate the ClassLoader and
execute arbitrary code on the system.
CVSS Base Score: 7.5
CVSS Temporal Score: See http://xforce.iss.net/xforce/xfdb/92889 for
more information
CVSS Environmental Score*: Undefined
CVSS Vector: (AV:N/AC:L/Au:N/C:P/I:P/A:P)
CVE-ID: CVE-2014-0113
Description: CookieInterceptor in Apache Struts before 2.3.16.2, when a
wildcard cookiesName value is used, does not properly restrict access
to the getClass method, which allows remote attackers to "manipulate"
the ClassLoader and execute arbitrary code via a crafted request. NOTE:
this vulnerability exists because of an incomplete fix for CVE-2014-0094.
CVSS Base Score: 7.5
CVSS Temporal Score: See http://xforce.iss.net/xforce/xfdb/92742 for
more information
CVSS Environmental Score*: Undefined
CVSS Vector: (AV:N/AC:L/Au:N/C:P/I:P/A:P)
CVE-ID: CVE-2014-0112
Description: ParametersInterceptor in Apache Struts before 2.3.16.2 does
not properly restrict access to the getClass method, which allows remote
attackers to "manipulate" the ClassLoader and execute arbitrary code via a
crafted request. NOTE: this vulnerability exists because of an incomplete
fix for CVE-2014-0094.
CVSS Base Score: 7.5
CVSS Temporal Score: See http://xforce.iss.net/xforce/xfdb/92740 for

CVSS Vector: (AV:N/AC:L/Au:N/C:P/I:P/A:P)
CVE-ID: CVE-2014-0094
Description: The ParametersInterceptor in Apache Struts before 2.3.16.1
allows remote attackers to "manipulate" the ClassLoader via the class
parameter, which is passed to the getClass method.
CVSS Base Score: 5
