#VU103324 Permissions, Privileges, and Access Controls in Apache Solr - CVE-2025-24814
Vulnerability identifier: #VU103324
Vulnerability risk: Low
CVSSv4.0: 4.4 [CVSS:4.0/AV:L/AC:L/AT:P/PR:L/UI:N/VC:H/VI:H/VA:H/SC:N/SI:N/SA:N/E:U/U:Clear]
CVE-ID:
CWE-ID:
CWE-264
Exploitation vector: Local
Exploit availability: No
Vulnerable software:
Apache Solr
Client/Desktop applications /
Other client software
Vendor: Apache Foundation
Description
The vulnerability allows a local user to escalate privileges on the system.
The vulnerability exists due to an error when handling configuration files. Solr instances that use the "FileSystemConfigSetService" component (the default in "standalone" or "user-managed" mode), and are running without authentication and authorization are vulnerable to a sort of privilege escalation wherein individual "trusted" configset files can be ignored in favor of potentially-untrusted replacements available elsewhere on the filesystem. These replacement config files are treated as "trusted" and can use "<lib>" tags to add to Solr's classpath, which an attacker might use to load malicious code as a searchComponent or other plugin.
Mitigation
Install updates from vendor's website.
