Multiple Security Vulnerabilities Affect IBM WebSphere Application Server in
IBM Cloud

Product:             WebSphere Application Server in IBM Cloud

Software version:    All Versions

Operating system(s): Linux

Reference #:         0793597

Security Bulletin

Summary

There are multiple security vulnerabilities that affect the IBM WebSphere
Application Server in the IBM Cloud.

There is a timing window where there could be a privilege escalation
vulnerability in WebSphere Application Server. There is a potential remote code
execution vulnerability in WebSphere Application Server. There is a potential
cross-site request forgery in WebSphere Application Server Admin Console. There
is a potential XXE injection vulnerability in the Knowledge Center used by
WebSphere Application Server. There is a potential information disclosure in
WebSphere Application Server. There is a potential for weaker than expected
security in WebSphere Application Server with SP800-131 transition mode and
SSL_TLSv2. There is a potential denial of service with the Google Guava library
that is used in WebSphere Application Server.

Vulnerability Details

CVEID: CVE-2018-1926
DESCRIPTION: IBM WebSphere Application Server Admin Console is vulnerable to
cross-site request forgery, caused by improper validation of user-supplied
input. By persuading a user to visit a malicious URL, a remote attacker could
send a specially-crafted request. An attacker could exploit this vulnerability
to perform CSRF attack and update available applications.
CVSS Base Score: 4.3

CVEID: CVE-2018-1996
DESCRIPTION: IBM WebSphere Application Server could provide weaker than
expected security, caused by the improper TLS configuration. A remote attacker
could exploit this vulnerability to obtain sensitive information using man in
the middle techniques.
CVSS Base Score: 5.3
CVSS Temporal Score: See https://exchange.xforce.ibmcloud.com/vulnerabilities/
154650

for the current score
CVSS Environmental Score*: Undefined

CVEID: CVE-2018-10237
DESCRIPTION: Google Guava is vulnerable to a denial of service, caused by
improper eager allocation checks in the AtomicDoubleArray and CompoundOrdering
class. By sending a specially-crafted data, a remote attacker could exploit
this vulnerability to cause a denial of service condition.
CVSS Base Score: 7.5
CVSS Temporal Score: See https://exchange.xforce.ibmcloud.com/vulnerabilities/
142508 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:H)
