Security Bulletin


Summary

There is a potential cross-site scripting vulnerability with the Installation Verification Tool of IBM WebSphere Application Server. There is a potential cross-site scripting vulnerability in the Cache Monitor web application in WebSphere Application Server. There is a potential code execution vulnerability in OpenID connect in WebSphere Application Server Liberty. Potential cross-site scripting vulnerability in WebSphere Application Server using Message Migration Utility (SIBMsgMigration). The Message Migration Utility is not deployed by default. You are only at risk if you have deployed the application. There is a potential directory traversal vulnerability in WebSphere Application Server. This is occurs when an Enterprise Bundle Archive (EBA) is installed into the Application Server that has a path external to the EBA. There is a potential privilege elevation vulnerability in WebSphere Application Server after migration from WebSphere Application Server Version 8 when a security domain is configured to use a federated repository other than global federated repository. There is a potential code execution vulnerability in OpenID connect in WebSphere Application Server Liberty.

Vulnerability Details

CVEID: CVE-2018-1643
DESCRIPTION: The Installation Verification Tool of 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: 6.1
CVSS Temporal Score: See https://exchange.xforce.ibmcloud.com/vulnerabilities/144588 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-2018-1767
DESCRIPTION: IBM WebSphere Application Server CacheMonitor 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: 6.1
CVSS Temporal Score: See https://exchange.xforce.ibmcloud.com/vulnerabilities/148621 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-2018-1798
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: 6.1
CVSS Temporal Score: See https://exchange.xforce.ibmcloud.com/vulnerabilities/149428 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-2018-1797
DESCRIPTION: IBM WebSphere Application Server using Enterprise bundle Archives (EBA) could allow a local attacker to traverse directories on the system. By persuading a victim to extract a specially-crafted ZIP archive containing "dot dot slash" sequences (../), an attacker could exploit this vulnerability to write to arbitrary files on the system. Note: This vulnerability is known as "Zip-Slip".
CVSS Base Score: 6.3
CVSS Temporal Score: See https://exchange.xforce.ibmcloud.com/vulnerabilities/149427 for the current score
CVSS Environmental Score*: Undefined
CVSS Vector: (CVSS:3.0/AV:L/AC:L/PR:N/UI:R/S:C/C:N/I:H/A:N)

CVEID: CVE-2018-1840
DESCRIPTION: IBM WebSphere Application Server could allow a remote attacker to gain elevated privileges on the system, caused when a security domain is configured to use a federated repository other than global federated repository and then migrated to a newer release of WebSphere Application Server.
CVSS Base Score: 6
CVSS Temporal Score: See https://exchange.xforce.ibmcloud.com/vulnerabilities/150813 for the current score
CVSS Environmental Score*: Undefined
CVSS Vector: (CVSS:3.0/AV:N/AC:H/PR:L/UI:N/S:C/C:L/I:L/A:L)

CVEID: CVE-2018-1851
DESCRIPTION: IBM WebSphere Application Server OpenID Connect could allow a remote attacker to execute arbitrary code on the system, caused by improper deserialization. By sending a specially-crafted request to the RP service, an attacker could exploit this vulnerability to execute arbitrary code.
CVSS Base Score: 7.3
CVSS Temporal Score: See https://exchange.xforce.ibmcloud.com/vulnerabilities/150999 for the current score
CVSS Environmental Score*: Undefined
CVSS Vector: (CVSS:3.0/AV:N/AC:L/PR:N/UI:N/S:U/C:L/I:L/A:L)
