Security Bulletin

Summary

IBM Cloud Private is vulnerable to Kibana vulnerabilities

Vulnerability Details

CVEID: CVE-2020-7015
DESCRIPTION: Elastic Kibana is vulnerable to cross-site scripting, caused by
improper validation of user-supplied input in TSVB visualization. A remote
attacker could exploit this vulnerability to inject malicious script into a Web
page which would be executed in a victim's Web browser within the security
context of the hosting Web site, once the page is viewed. An attacker could use
this vulnerability to steal the victim's cookie-based authentication
credentials.
CVSS Base score: 6.1
CVSS Temporal Score: See: https://exchange.xforce.ibmcloud.com/vulnerabilities/
182944 for the current score.

CVEID: CVE-2020-7013
DESCRIPTION: Elastic Kibana could allow a remote authenticated attacker to
execute arbitrary code on the system, caused by a prototype pollution flaw in
