Security Bulletin: B2B API of IBM Sterling B2B Integrator is vulnerable to multiple issues due to FasterXML jackson-databind

Description

## Summary IBM Sterling B2B Integrator has addressed the security vulnerabilities in jackson-databind in B2B API. ## Vulnerability Details ** CVEID: **[CVE-2019-20330](<https://vulners.com/cve/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](<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](<https://vulners.com/cve/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](<https://exchange.xforce.ibmcloud.com/vulnerabilities/162849>) for the current score.

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](<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](<https://vulners.com/cve/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](<https://exchange.xforce.ibmcloud.com/vulnerabilities/185699>) for the current score.
