{"schemaVersion":3,"id":"UBUNTU-CVE-2019-17558","aliases":[],"status":"published","duplicateOf":null,"title":null,"description":"Apache Solr 5.0.0 to Apache Solr 8.3.1 are vulnerable to a Remote Code Execution through the VelocityResponseWriter. A Velocity template can be provided through Velocity templates in a configset `velocity/` directory or as a parameter. A user defined configset could contain renderable, potentially malicious, templates. Parameter provided templates are disabled by default, but can be enabled by setting `params.resource.loader.enabled` by defining a response writer with that setting set to `true`. Defining a response writer requires configuration API access. Solr 8.4 removed the params resource loader entirely, and only enables the configset-provided template rendering when the configset is `trusted` (has been uploaded by an authenticated user).","dates":{"published":"2019-12-30T17:15:00.000Z","modified":"2026-02-04T03:38:13.788Z","reserved":null,"kevAdded":[],"kevDue":[]},"cvss":{"headline":{"score":7.5,"severity":"high","version":"3.1","versionLabel":"v3.1","source":"OSV · Ubuntu","vector":"CVSS:3.1/AV:N/AC:H/PR:L/UI:N/S:U/C:H/I:H/A:H","computed":true,"selection":"version-preference"},"metrics":[{"version":"3.1","versionLabel":"v3.1","source":"OSV · Ubuntu","score":7.5,"severity":"high","vector":"CVSS:3.1/AV:N/AC:H/PR:L/UI:N/S:U/C:H/I:H/A:H","exploitability":4.1,"impact":9.8,"computed":true}]},"epss":{"probability":null,"percentile":null,"severity":"unknown","asOf":null,"change":{"pp":null,"baselineDate":null,"baselineScore":null},"history":[],"last30":[]},"kev":{"state":"not-listed","entries":[],"listedCount":0,"totalCatalogs":3,"catalogs":[{"source":"cisa","label":"CISA","listed":false,"entry":null},{"source":"enisa","label":"ENISA","listed":false,"entry":null},{"source":"circl","label":"CIRCL","listed":false,"entry":null}]},"ransomware":{"state":"none-recorded","sources":[]},"exploits":[],"exploitCount":0,"weaknesses":[],"affected":[{"vendor":"ubuntu","product":"lucene-solr","name":"lucene-solr","label":"lucene-solr","ecosystem":"Ubuntu","cpePart":null,"purl":"pkg:deb/ubuntu/lucene-solr","purlType":"deb","versions":[{"text":"All versions","noFixRecorded":true,"fixedIn":null}],"versionsText":"All versions (No fix recorded)","eol":null,"hubHref":null}],"affectedCount":1,"eol":{"hasEol":false,"count":0},"references":[{"url":"https://ubuntu.com/security/CVE-2019-17558","label":"ubuntu.com/security/CVE-2019-17558","hostname":"ubuntu.com","tags":["REPORT"]},{"url":"https://www.openwall.com/lists/oss-security/2019/12/30/1","label":"www.openwall.com/lists/oss-security/2019/12/30/1","hostname":"www.openwall.com","tags":["REPORT"]},{"url":"https://issues.apache.org/jira/browse/SOLR-13971","label":"issues.apache.org/jira/browse/SOLR-13971","hostname":"issues.apache.org","tags":["REPORT"]},{"url":"https://issues.apache.org/jira/browse/SOLR-14025","label":"issues.apache.org/jira/browse/SOLR-14025","hostname":"issues.apache.org","tags":["REPORT"]},{"url":"https://www.cve.org/CVERecord?id=CVE-2019-17558","label":"www.cve.org/CVERecord?id=CVE-2019-17558","hostname":"www.cve.org","tags":["REPORT"]},{"url":"https://www.cisa.gov/known-exploited-vulnerabilities-catalog","label":"www.cisa.gov/known-exploited-vulnerabilities-catalog","hostname":"www.cisa.gov","tags":["REPORT"]}],"lineage":{"upstream":[],"downstream":[],"duplicates":[],"related":["CVE-2019-17558"]},"timeline":[{"kind":"published","date":"2019-12-30T17:15:00.000Z","label":"Published","detail":"Vulnerability first disclosed.","source":null},{"kind":"modified","date":"2026-02-04T03:38:13.788Z","label":"Last modified","detail":"Vulnerability information updated.","source":null}],"risk":{"score":30,"level":"medium","profile":"Default","thresholds":{"critical":75,"high":50,"medium":25,"low":10}},"meta":{"dataAsOf":"2026-10-20T20:02:56.079Z","stale":false,"partial":false}}
