Incorrect Authorization in Kibana Leading to Information Disclosure

Incorrect Authorization (CWE-863) in Kibana can lead to unauthorized information disclosure via Accessing Functionality Not Properly Constrained by ACLs (CAPEC-1). Under certain conditions, a low-privileged authenticated user can access response action data that they are not authorized to view.

Elastic Agent / Elastic Endpoint Security local API key disclosure

Exposure of sensitive information to local unauthorized actors in Elastic Agent and Elastic Security Endpoint can lead to loss of confidentiality and impersonation of Endpoint to the Elastic Stack. This issue was identified by Elastic engineers and Elastic has no indication that it is known or has been exploited by malicious actors.

An issue was discovered in the quarantine feature of Elastic Endpoint Security and Elastic Endgame for Windows, which could allow unprivileged users to elevate their privileges to those of the LocalSystem account.

An issue was discovered in the rollback feature of Elastic Endpoint Security for Windows, which could allow unprivileged users to elevate their privileges to those of the LocalSystem account.

An issue was discovered in the rollback feature of Elastic Endpoint Security for Windows, which could allow unprivileged users to elevate their privileges to those of the LocalSystem account.

Elastic Endpoint Insertion of Sensitive Information into Log File

If Elastic Endpoint (v7.9.0 - v8.10.3) is configured to use a non-default option in which the logging level is explicitly set to debug, and when Elastic Agent is simultaneously configured to collect and send those logs to Elasticsearch, then Elastic Agent API keys can be viewed in Elasticsearch in plaintext. These API keys could be used to write arbitrary data and read Elastic Endpoint user artifacts.

A local privilege escalation (LPE) issue was discovered in the ransomware canaries features of Elastic Endpoint Security for Windows, which could allow unprivileged users to elevate their privileges to those of the LocalSystem account.
