Summary

IBM Sterling File Gateway has addressed the following multiple vulnerabilities
caused by Apach Struts 1.1

Vulnerability Details

CVEID: CVE-2008-2025
DESCRIPTION: Apache Struts is vulnerable to cross-site scripting, caused by
improper validation of user-supplied input. A remote attacker could exploit
this vulnerability using a specially-crafted URL to execute script in a
victim''s Web browser within the security context of the hosting Web site, once
the URL is clicked. An attacker could use this vulnerability to steal the
victim''s cookie-based authentication credentials.
CVSS Base Score: 4.3
CVSS Temporal Score: See https://exchange.xforce.ibmcloud.com/vulnerabilities/
49712 for the current score
CVSS Environmental Score*: Undefined
CVSS Vector: (AV:N/AC:M/Au:N/C:N/I:P/A:N)

CVEID: 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 https://exchange.xforce.ibmcloud.com/vulnerabilities/
92889 for the current score
CVSS Environmental Score*: Undefined
CVSS Vector: (AV:N/AC:L/Au:N/C:P/I:P/A:P)

CVEID: CVE-2015-0899
DESCRIPTION: Apache Struts could allow a remote attacker to bypass security
restrictions, caused by an error in the MultiPageValidator implementation. An
attacker could exploit this vulnerability using a modified page parameter to
bypass restrictions and launch further attacks on the system. This
vulnerability also affects other products.
CVSS Base Score: 4.3
CVSS Temporal Score: See https://exchange.xforce.ibmcloud.com/vulnerabilities/
101770 for the current score

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

CVEID: CVE-2016-1181
DESCRIPTION: Apache Struts could allow a remote attacker to execute arbitrary
code on the system, caused by the failure to protect against unintended remote
operations against components on server memory by the ActionForm instance. An
attacker could exploit this vulnerability to execute arbitrary code on the
system.
CVSS Base Score: 8.1
CVSS Temporal Score: See https://exchange.xforce.ibmcloud.com/vulnerabilities/

CVEID: CVE-2016-1182
DESCRIPTION: Apache Struts could allow a remote attacker to bypass security
restrictions, caused by the improper validation of input by the Validator. An
attacker could exploit this vulnerability to modify validation rules and error
messages.
