Security Bulletin: Multiple security vulnerabilities has been identified in Websphere Application Server shipped with Tivoli Integrated Portal (CVE-2016-0359, CVE-2016-1181, CVE-2016-1182)

Summary

Embedded Websphere Application Server (eWAS) is shipped as a component of Tivoli Integrated Portal and eWAS has been affected by multiple security vulnerabilities.

Vulnerability Details

CVEID: CVE-2016-0359**
DESCRIPTION:** IBM WebSphere Application Server is vulnerable to HTTP response splitting attacks. A remote attacker could exploit this vulnerability using specially-crafted URL to cause the server to return a split response, once the URL is clicked. This would allow the attacker to perform further attacks, such as Web cache poisoning, cross-site scripting, and possibly obtain sensitive information.
CVSS Base Score: 6.1
CVSS Temporal Score: See https://exchange.xforce.ibmcloud.com/vulnerabilities/111929 for the current score
CVSS Environmental Score*: Undefined
CVSS Vector: (CVSS:3.0/AV:N/AC:L/PR:N/UI:R/S:C/C:L/I:L/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/113852 for the current score

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.
CVSS Base Score: 4.8

Security Bulletin: Vulnerabilities in Apache Struts affects IBM WebSphere Application Server (CVE-2016-1181 and CVE-2016-1182)

The Websphere security bulletin above provides a link to the required iFix to remediate the vulnerability. However, the iFix requires either eWAS 7.0.0.33 or higher installed.
TIP does not support upgrading Websphere fixpack independently. TIP 2.2.0.15 or TIP 2.2.0.17 must be applied which will upgrade eWAS to 7.0.0.33 and above. Once TIP FP has been applied, the Websphere iFix can be applied as described in the Websphere bulletin.

Workarounds and Mitigations

Please refer to WAS iFix as described above
