Snyk has a proof-of-concept or detailed explanation of how to exploit this vulnerability.
The probability is the direct output of the EPSS model, and conveys an overall sense of the threat of exploitation in the wild. The percentile measures the EPSS probability relative to all known EPSS scores. Note: This data is updated daily, relying on the latest available EPSS model version.

org.apache.solr:solr-core is an open source enterprise search platform built on Apache Lucene
Affected versions of this package are vulnerable to Unrestricted Upload of File with Dangerous Type due to the ConfigSets
API accepting Java jar and class files. When backing up Solr Collections, these configSet
files are saved to disk using the LocalFileSystemRepository
, which is the default for backups. If the backup was saved to a directory that Solr uses in its ClassPath/ClassLoaders, then the jar and class files become available for use with any ConfigSet
, regardless of trust level.
Note: This vulnerability is most severe when Authorization is not enabled, which is strongly recommended against. With Authorization enabled it is limited to extending the Backup permissions with the ability to add libraries.
