Vulnerability Details

CVEID: CVE-2014-0114
DESCRIPTION: Apache Commons BeanUtils, as distributed in lib/
commons-beanutils-1.8.0.jar in Apache Struts 1.x through 1.3.10 and in other
products requiring commons-beanutils through 1.9.2, does not suppress the class
property, which allows remote attackers to "manipulate" the ClassLoader and
execute arbitrary code via the class parameter, as demonstrated by the passing
of this parameter to the getClass method of the ActionForm object in Struts 1.
CVSS Base Score: 7.5
CVSS Temporal Score: See http://xforce.iss.net/xforce/xfdb/92889 for the
current score
CVSS Environmental Score*: Undefined
CVSS Vector: (AV:N/AC:L/Au:N/C:P/I:P/A:P)

CVEID: CVE-2017-17485
DESCRIPTION: Jackson-databind could allow a remote attacker to execute
arbitrary code on the system, caused by a flaw in the default-typing feature.
An attacker could exploit this vulnerability to execute arbitrary code on the
system.
CVSS Base Score: 9.8
CVSS Temporal Score: See https://exchange.xforce.ibmcloud.com/vulnerabilities/
137340 for the current score
CVSS Environmental Score*: Undefined
CVSS Vector: (CVSS:3.0/AV:N/AC:L/PR:N/UI:N/S:U/C:H/I:H/A:H)

CVEID: CVE-2018-5968
DESCRIPTION: FasterXML jackson-databind could allow a remote attacker to
execute arbitrary code on the system, caused by deserialization flaws. By using
two different gadgets that bypass a blacklist, an attacker could exploit this
vulnerability to execute arbitrary code on the system.
CVSS Base Score: 7.3
CVSS Temporal Score: See https://exchange.xforce.ibmcloud.com/vulnerabilities/
138088 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)

CVEID: CVE-2017-15095
DESCRIPTION: Jackson Library could allow a remote attacker to execute arbitrary
code on the system, caused by a deserialization flaw in the readValue() method
of the ObjectMapper. By sending specially crafted data, an attacker could
exploit this vulnerability to execute arbitrary code on the system.
CVSS Base Score: 9.8
CVSS Temporal Score: See https://exchange.xforce.ibmcloud.com/vulnerabilities/
135123 for the current score
CVSS Environmental Score*: Undefined
CVSS Vector: (CVSS:3.0/AV:N/AC:L/PR:N/UI:N/S:U/C:H/I:H/A:H)

CVEID: CVE-2017-7525
DESCRIPTION: A deserialization flaw was discovered in the jackson-databind,
versions before 2.6.7.1, 2.7.9.1 and 2.8.9, which could allow an
unauthenticated user to perform code execution by sending the maliciously
crafted input to the readValue method of the ObjectMapper.
CVSS Base Score: 9.8
CVSS Temporal Score: See https://exchange.xforce.ibmcloud.com/vulnerabilities/
134639 for the current score
CVSS Environmental Score*: Undefined
CVSS Vector: (CVSS:3.0/AV:N/AC:L/PR:N/UI:N/S:U/C:H/I:H/A:H)

CVEID: CVE-2018-7489
DESCRIPTION: FasterXML jackson-databind could allow a remote attacker to
execute arbitrary code on the system, caused by a deserialization flaw in the
readValue method of the ObjectMapper. By sending specially crafted JSON input,
an attacker could exploit this vulnerability to execute arbitrary code on the
system.
