CVEID:
 CVE-2016-5547
DESCRIPTION:
 An unspecified vulnerability related to the Libraries component could allow a remote attacker to cause a denial of service resulting in a low availability impact using unknown attack vectors.
CVSS Base Score: 5.3
CVSS Temporal Score: See https://exchange.xforce.ibmcloud.com/vulnerabilities/120871 for the current score
CVSS Environmental Score*: Undefined
CVSS Vector: (CVSS:3.0/AV:N/AC:L/PR:N/UI:N/S:U/C:N/I:N/A:L)

CVEID:
 CVE-2016-2183
DESCRIPTION:
 OpenSSL could allow a remote attacker to obtain sensitive information, caused by an error in the DES/3DES cipher, used as a part of the SSL/TLS protocol. By capturing large amounts of encrypted traffic between the SSL/TLS server and the client, a remote attacker able to conduct a man-in-the-middle attack could exploit this vulnerability to recover the plaintext data and obtain sensitive information. This vulnerability is known as the SWEET32 Birthday attack.
CVSS Base Score: 3.7
CVSS Temporal Score: See https://exchange.xforce.ibmcloud.com/vulnerabilities/116337 for the current score
CVSS Environmental Score*: Undefined
CVSS Vector: (CVSS:3.0/AV:N/AC:H/PR:N/UI:N/S:U/C:L/I:N/A:N)



CVEID: CVE-2017-1121
DESCRIPTION:
IBM WebSphere Application Server is vulnerable to cross-site scripting. This vulnerability allows users to embed arbitrary JavaScript code in the Web UI thus altering the intended functionality potentially leading to credentials disclosure within a trusted session.
CVSS Base Score: 5.4
CVSS Temporal Score: See https://exchange.xforce.ibmcloud.com/vulnerabilities/121173 for the current score
CVSS Environmental Score*: Undefined
CVSS Vector: (CVSS:3.0/AV:N/AC:L/PR:L/UI:R/S:C/C:L/I:L/A:N)

CVEID: CVE-2016-8743
DESCRIPTION:
Apache HTTPD is vulnerable to HTTP response splitting attacks, caused by improper validation of user-supplied input. A remote attacker could exploit this vulnerability to inject arbitrary HTTP headers and 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 or cross-site scripting, and possibly obtain sensitive information.
CVSS Base Score: 6.1
CVSS Temporal Score: See https://exchange.xforce.ibmcloud.com/vulnerabilities/119917 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-2016-2126
DESCRIPTION:
Samba could allow a remote authenticated attacker to gain elevated privileges on the system, caused by the failure of handling the PAC checksum. By using a specially-crafted Kerberos ticket, an authenticated attacker could exploit this vulnerability to gain privileges or cause the winbindd process to crash.
CVSS Base Score: 6.3
CVSS Temporal Score: See https://exchange.xforce.ibmcloud.com/vulnerabilities/119906 for the current score
CVSS Environmental Score*: Undefined
CVSS Vector: (CVSS:3.0/AV:N/AC:L/PR:L/UI:N/S:U/C:L/I:L/A:L)

CVEID: CVE-2016-2125
DESCRIPTION:
Samba could allow a remote authenticated attacker to gain elevated privileges on the system, caused by forwarding a Ticket Granting Ticket (TGT) to other service when using Kerberos authentication. An attacker could exploit this vulnerability to impersonate the authenticated user and gain elevated privileges on the system.
CVSS Base Score: 8.8
CVSS Temporal Score: See https://exchange.xforce.ibmcloud.com/vulnerabilities/119968 for the current score
CVSS Environmental Score*: Undefined
CVSS Vector: (CVSS:3.0/AV:N/AC:L/PR:L/UI:N/S:U/C:H/I:H/A:H)

CVEID: CVE-2016-2123
DESCRIPTION:
Samba is vulnerable to a heap-based buffer overflow, caused by an integer wrap flaw in the ndr_pull_dnsp_name() function. By writing specially crafted data to the Samba Active Directory ldb database dnsRecord attribute, a remote authenticated attacker could overflow a buffer and execute arbitrary code on the system with elevated privileges.
CVSS Base Score: 8.8
CVSS Temporal Score: See https://exchange.xforce.ibmcloud.com/vulnerabilities/119969 for the current score
CVSS Environmental Score*: Undefined
CVSS Vector: (CVSS:3.0/AV:N/AC:L/PR:L/UI:N/S:U/C:H/I:H/A:H)

Affected Products and Versions

This vulnerability affects the following versions and releases of IBM WebSphere Application Server:

  • Version 9.0
  • Version 8.5.5

Remediation/Fixes

To patch an existing service instance requires two steps:

1. To update WebSphere Application Server refer to the IBM WebSphere Application Server bulletins listed below:

Security Bulletin: Multiple vulnerabilities in IBM® Java SDK affects WebSphere Application Server January 2017 CPU

Security Bulletin: Potential Cross-site scripting vulnerability in WebSphere Application Server (CVE-2017-1121)
