Security Bulletin
Summary
IBM Tivoli Monitoring for Virtual Environments Agent for Linux Kernel-based Virtual Machines is vulnerable to Apache HttpClient and jackson-mapper as described in 220912, CVE-2020-13956, CVE-2019-10202, CVE-2019-10172. The fix includes upgrading required libraries to latest version.
Vulnerability Details
CVEID: CVE-2020-13956
DESCRIPTION: Apache HttpClient could allow a remote attacker to bypass security restrictions, caused by the improper handling of malformed authority component in request URIs. By passing request URIs to the library as java.net.URI object, an attacker could exploit this vulnerability to pick the wrong target host for request execution.
CVSS Base score: 5.3
CVSS Temporal Score: See: https://exchange.xforce.ibmcloud.com/vulnerabilities/189572 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-2019-10202
DESCRIPTION: Red Hat JBoss Enterprise Application Platform (EAP) could allow a remote attacker to execute arbitrary code on the system, caused by improper deserialization in Codehaus. By sending a specially-crafted request, an attacker could exploit this vulnerability to execute arbitrary code on the system.
CVSS Base score: 8.1
CVSS Temporal Score: See: https://exchange.xforce.ibmcloud.com/vulnerabilities/168251 for the current score.
CVSS Vector: (CVSS:3.0/AV:N/AC:H/PR:N/UI:N/S:U/C:H/I:H/A:H)
CVEID: CVE-2019-10172
DESCRIPTION: Jackson-mapper-asl could allow a remote attacker to obtain sensitive information, caused by an XML external entity (XXE) error when processing XML data. By sending a specially-crafted XML data, a remote attacker could exploit this vulnerability to obtain sensitive information.
CVSS Base score: 5.9

Disclaimer
According to the Forum of Incident Response and Security Teams (FIRST), the Common Vulnerability Scoring System (CVSS) is an "industry open standard designed to convey vulnerability severity and help to determine urgency and priority of response." IBM PROVIDES THE CVSS SCORES ""AS IS"" WITHOUT WARRANTY OF ANY KIND, INCLUDING THE IMPLIED WARRANTIES OF MERCHANTABILITY AND FITNESS FOR A PARTICULAR PURPOSE. CUSTOMERS ARE RESPONSIBLE FOR ASSESSING THE IMPACT OF ANY ACTUAL OR POTENTIAL SECURITY VULNERABILITY. In addition to other efforts to address potential vulnerabilities, IBM periodically updates the record of components contained in our product offerings. As part of that effort, if IBM identifies previously unidentified packages in a product/service inventory, we address relevant vulnerabilities regardless of CVE date. Inclusion of an older CVEID does not demonstrate that the referenced product has been used by IBM since that date, nor that IBM was aware of a vulnerability as of that date. We are making clients aware of relevant vulnerabilities as we become aware of them. "Affected Products and Versions" referenced in IBM Security Bulletins are intended to be only products and versions that are supported by IBM and have not passed their end-of-support or warranty date. Thus, failure to reference unsupported or extended-support products and versions in this Security Bulletin does not constitute a determination by IBM that they are unaffected by the vulnerability. Reference to one or more unsupported versions in this Security Bulletin shall not create an obligation for IBM to provide fixes for any unsupported or extended-support products or versions.
