Vulnerability Details

CVEID:CVE-2019-20330
**DESCRIPTION:**A lacking of certain net.sf.ehcache blocking in FasterXML jackson-databind has an unknown impact and attack vector.
CVSS Base score: 7.3
CVSS Temporal Score: See: https://exchange.xforce.ibmcloud.com/vulnerabilities/173897 for the current score.
CVSS Vector: (CVSS:3.0/AV:N/AC:L/PR:N/UI:N/S:U/C:L/I:L/A:L)

CVEID:CVE-2019-12384
**DESCRIPTION:**FasterXML jackson-databind could allow a remote attacker to execute arbitrary code on the system, caused by the failure to block the logback-core class from polymorphic deserialization. By sending a specially-crafted JSON message, 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/162849 for the current score.
CVSS Vector: (CVSS:3.0/AV:N/AC:L/PR:N/UI:N/S:U/C:H/I:H/A:H)

CVEID:CVE-2018-14720
**DESCRIPTION:**FasterXML jackson-databind could allow a remote attacker to obtain sensitive information, caused by an XML external entity (XXE) error when processing XML data by JDK classes. By sending a specially-crafted XML data. A remote attacker could exploit this vulnerability to obtain sensitive information.
CVSS Base score: 5.3
CVSS Temporal Score: See: https://exchange.xforce.ibmcloud.com/vulnerabilities/155137 for the current score.
CVSS Vector: (CVSS:3.0/AV:N/AC:L/PR:N/UI:N/S:U/C:L/I:N/A:N)

CVEID:CVE-2020-8840
**DESCRIPTION:**Multiple Huawei products could allow a remote attacker to execute arbitrary code on the system, caused by the deserialization of data without proper validation. By sending a specially crafted request, an attacker could exploit this vulnerability to execute arbitrary code on the system.
CVSS Base score: 5.3
CVSS Temporal Score: See: https://exchange.xforce.ibmcloud.com/vulnerabilities/185699 for the current score.
CVSS Vector: (CVSS:3.0/AV:N/AC:L/PR:N/UI:N/S:U/C:N/I:L/A:N)

CVEID:CVE-2018-19361
**DESCRIPTION:**An unspecified error with failure to block the openjpa class from polymorphic deserialization in FasterXML jackson-databind has an unknown impact and attack vector.
CVSS Base score: 5.3
CVSS Temporal Score: See: https://exchange.xforce.ibmcloud.com/vulnerabilities/155092 for the current score.
CVSS Vector: (CVSS:3.0/AV:N/AC:L/PR:N/UI:N/S:U/C:N/I:L/A:N)

CVEID:CVE-2020-36518
**DESCRIPTION:**FasterXML jackson-databind is vulnerable to a denial of service, caused by a Java StackOverflow exception. By using a large depth of nested objects, a remote attacker could exploit this vulnerability to cause a denial of service.
CVSS Base score: 7.5
CVSS Temporal Score: See: https://exchange.xforce.ibmcloud.com/vulnerabilities/222319 for the current score.
CVSS Vector: (CVSS:3.0/AV:N/AC:L/PR:N/UI:N/S:U/C:N/I:N/A:H)
