Details
A vulnerability classified as critical has been found in Apache Solr up to 7.6. This affects an unknown part of the component Node Handler. The manipulation as part of a Request leads to a authorization vulnerability. CWE is classifying the issue as CWE-863. The product performs an authorization check when an actor attempts to access a resource or perform an action, but it does not correctly perform the check. This allows attackers to bypass intended access restrictions. This is going to have an impact on confidentiality, integrity, and availability. The summary by CVE is:
In Apache Solr, the cluster can be partitioned into multiple collections and only a subset of nodes actually host any given collection. However, if a node receives a request for a collection it does not host, it proxies the request to a relevant node and serves the request. Solr bypasses all authorization settings for such requests. This affects all Solr versions prior to 7.7 that use the default authorization mechanism of Solr (RuleBasedAuthorizationPlugin).
The bug was discovered 04/24/2019. The weakness was released 04/01/2020. This vulnerability is uniquely identified as CVE-2018-11802 since 06/05/2018. The exploitability is told to be easy. It is possible to initiate the attack remotely. A authentication is necessary for exploitation. The technical details are unknown and an exploit is not publicly available.
The vulnerability was handled as a non-public zero-day exploit for at least 343 days. During that time the estimated underground price was around $5k-$25k.
Upgrading to version 7.7 eliminates this vulnerability.
