Vulnerability Details
CVEID: CVE-2019-4080
DESCRIPTION: IBM WebSphere Application Server Admin Console is vulnerable to a
potential denial of service, caused by improper parameter parsing. A remote
attacker could exploit this to consume all available CPU resources.
CVSS Base Score: 6.5
CVSS Temporal Score: See https://exchange.xforce.ibmcloud.com/vulnerabilities/
157380 for the current score
CVSS Environmental Score*: Undefined
CVSS Vector: (CVSS:3.0/AV:N/AC:L/PR:L/UI:N/S:U/C:N/I:N/A:H)
CVEID: CVE-2019-4046
DESCRIPTION: IBM WebSphere Application Server is vulnerable to a denial of
service, caused by improper handling of request headers. A remote attacker
could exploit this vulnerability to cause the consumption of Memory.
CVSS Base Score: 5.9
CVSS Temporal Score: See https://exchange.xforce.ibmcloud.com/vulnerabilities/
156242 for the current score
CVSS Environmental Score*: Undefined
CVSS Vector: (CVSS:3.0/AV:N/AC:H/PR:N/UI:N/S:U/C:N/I:N/A:H)
CVEID: CVE-2019-4030
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/
155946 for the current score
CVSS Environmental Score*: Undefined

CVEID: CVE-2018-1902
DESCRIPTION: IBM WebSphere Application Server could allow a remote attacker to
spoof connection information which could be used to launch further attacks
against the system.
CVSS Base Score: 3.1
CVSS Temporal Score: See https://exchange.xforce.ibmcloud.com/vulnerabilities/
152531 for the current score
CVSS Environmental Score*: Undefined
CVSS Vector: (CVSS:3.0/AV:N/AC:H/PR:L/UI:N/S:U/C:N/I:L/A:N)
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
