CWE-ID: CWE-522

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 user to gain access to sensitive information.

The vulnerability exists due to an insecure redaction logic in the "/admin/info/properties" endpoint that hid only system properties with the "password" string inside their names. A remote user with "config-read" permission can obtain credentials stored in other properties, such as "basicauth" or "aws.secretKey".

Mitigation
Install updates from vendor's website.
