Security Bulletin: Vulnerabilities in Elasticsearch affect watsonx.data

Summary

Elasticsearch is vulnerable to local authenticated attacks to obtain sensitive information and denial of service attacks. These can affect watsonx.data.

Vulnerability Details

CVEID:CVE-2023-31417
**DESCRIPTION:**Elasticsearch could allow a local authenticated attacker to obtain sensitive information, caused by the insertion of sensitive information into the log files. By leveraging the deprecated _xpack/security API, an attacker could exploit this vulnerability to obtain sensitive information, and use this information to launch further attacks against the affected system.
CVSS Base score: 4.1
CVSS Temporal Score: See: https://exchange.xforce.ibmcloud.com/vulnerabilities/269880 for the current score.

CVEID:CVE-2023-46673
**DESCRIPTION:**Elastic Elasticsearch is vulnerable to a denial of service, caused by improper handling of exceptional conditions. By sending a specially crafted request using the Simulate Pipeline API, a remote authenticated attacker could exploit this vulnerability to cause an Elasticsearch node to crash.
CVSS Base score: 6.5
CVSS Temporal Score: See: https://exchange.xforce.ibmcloud.com/vulnerabilities/272207 for the current score.

CVEID:CVE-2023-31419
**DESCRIPTION:**Elasticsearch is vulnerable to a denial of service, caused by a stack-based buffer overflow in the _search API. By sending a specially crafted request, a remote authenticated attacker could exploit this vulnerability to cause a denial of service.
CVSS Base score: 6.5
CVSS Temporal Score: See: https://exchange.xforce.ibmcloud.com/vulnerabilities/266978 for the current score.

CVEID:CVE-2023-31418
**DESCRIPTION:**Elastic Elasticsearch is vulnerable to a denial of service, caused by uncontrolled resource consumption. By sending a moderate number of malformed HTTP requests, a remote attacker could exploit this vulnerability to force an Elasticsearch node to exit with an OutOfMemory error.
CVSS Base score: 7.5
CVSS Temporal Score: See: https://exchange.xforce.ibmcloud.com/vulnerabilities/270341 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)

CVEID:CVE-2024-23450
**DESCRIPTION:**Elastic Elasticsearch is vulnerable to a denial of service, caused by a flaw when processing a document in a deeply nested pipeline on an ingest node. By sending a specially crafted document, a remote authenticated attacker could exploit this vulnerability to cause an uncontrolled resource consumption, and results in a denial of service condition.
CVSS Base score: 4.9
