CVE-2020-13941
Description
A flaw was found in Solr. The Replication handler allows commands backup, restore, and delete backup that take non-validated allocation parameters which may result in the exfiltration of sensitive data such as OS user hashes (NTLM/LMhashes). The highest threat from this vulnerability is to data confidentiality and integrity as well as system availability.
Statement
Red Hat JBoss Fuse 6, Red Hat Fuse 7, and Red Hat Integration Camel K using camel-solr are not directly affected by this vulnerability as the camel-solr component uses the client library solr-j and the vulnerability lies in the solr server itself. We advise customers using solr to investigate the usage of the server and ensure it is safe.
Common Vulnerability Scoring System (CVSS) Score Details
Info alert:Important note
CVSS scores for open source components depend on vendor-specific factors (e.g. version or build chain). Therefore, Red Hat's score and impact rating can be different from NVD and other vendors. Red Hat remains the authoritative CVE Naming Authority (CNA) source for its products and services (see Red Hat classifications).
The following CVSS metrics and score provided are preliminary and subject to review.
