Security Bulletin

This security bulletin contains information about 2 vulnerabilities.

1) Permissions, Privileges, and Access Controls

EUVDB-ID: #VU91269

Risk: Medium

CVSSv3.1: 6.2 [CVSS:3.1/AV:N/AC:L/PR:L/UI:N/S:U/C:L/I:H/A:N/E:U/RL:O/RC:C]

CVE-ID: CVE-2024-23445

CWE-ID: CWE-264 - Permissions, Privileges, and Access Controls

Exploit availability: No

Description

The vulnerability allows a remote user to gain access to sensitive information.

The vulnerability exists due to improperly imposed security restrictions on the API key for the cross-cluster search. If a cross-cluster API key restricts search for a given index using the query or the field_security parameter, and the same cross-cluster API key also grants replication for the same index, the search restrictions are not enforced during cross cluster search operations and search results may include documents and terms that should not be returned. A remote user can gain access to potentially sensitive information.

Mitigation

Install updates from vendor's website.

Vulnerable software versions

Elasticsearch: 8.10.0 - 8.13.4

Q & A

Can this vulnerability be exploited remotely?

Yes. This vulnerability can be exploited by a remote authenticated user via the Internet.

No. We are not aware of malware exploiting this vulnerability.

2) Uncaught exception

EUVDB-ID: #VU91270

Risk: Low

CVSSv3.1: 4.3 [CVSS:3.1/AV:N/AC:L/PR:H/UI:N/S:U/C:N/I:N/A:H/E:U/RL:O/RC:C]

CVE-ID: CVE-2024-37280

CWE-ID: CWE-248 - Uncaught Exception

Exploit availability: No

Description

The vulnerability allows a remote user to perform a denial of service (DoS) attack.

The vulnerability exists due to an uncaught exception affecting document ingestion when an index template contains a dynamic field mapping of “passthrough” type. Under certain circumstances, ingesting documents in this index would cause a StackOverflow exception to be thrown and ultimately lead to a denial of service.

Mitigation

Install updates from vendor's website.
