CVE-ID: CVE-2024-45217

CWE-ID: CWE-345

Exploitation vector: Network

Exploit availability: No

Vulnerable software:
Apache Solr
Client/Desktop applications / Other client software

Vendor: Apache Foundation

Description

The vulnerability allows a remote attacker to compromise the affected instance.

The vulnerability exists due to ConfigSets created during a backup restore command are trusted implicitly. New ConfigSets that are created via a Restore command, which copy a configSet from the backup and give it a new name, are created without setting the "trusted" metadata. ConfigSets that do not contain the flag are trusted implicitly if the metadata is missing, therefore this leads to "trusted" ConfigSets that may not have been created with an Authenticated request.

Mitigation
Install updates from vendor's website.
