Vulnerability Details
CVEID: CVE-2018-1904
DESCRIPTION: IBM WebSphere Application Server could allow remote attackers to
execute arbitrary Java code through an administrative client class with a
serialized object from untrusted sources.
CVSS Base Score: 8.1
CVSS Temporal Score: See https://exchange.xforce.ibmcloud.com/vulnerabilities/
152533
for the current score
CVSS Environmental Score*: Undefined
CVSS Vector: (CVSS:3.0/AV:N/AC:H/PR:N/UI:N/S:U/C:H/I:H/A:H)
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-2018-1901
DESCRIPTION: IBM WebSphere Application Server could allow a remote attacker to
temporarily gain elevated privileges on the system, caused by incorrect cached
value being used.
CVSS Base Score: 5
CVSS Temporal Score: See https://exchange.xforce.ibmcloud.com/vulnerabilities/
152530
for the current score

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
CVSS Temporal Score: See https://exchange.xforce.ibmcloud.com/vulnerabilities/
152992
for the current score

CVEID: CVE-2018-1957
DESCRIPTION: IBM WebSphere Application Server could allow sensitive information
to be available caused by mishandling of data by the application based on an
incorrect return by the httpServletRequest#authenticate() API when an
unprotected URI is accessed.
