Security readout for executives and security teams
Plain-English summary
CVE-2015-8795 is a cross-site scripting issue in the Apache Solr Admin UI before 5.1. A crafted value could be rendered as script or HTML on specific admin pages, potentially affecting administrators who view it. The source bundle does not provide CVSS, affected CPEs, or evidence of active exploitation.
Executive priority
Prioritize remediation if legacy Solr Admin UI is exposed beyond a tightly controlled administrator group. This is not documented as actively exploited in the provided sources, but XSS in an administrative interface can support session or privilege abuse.
Technical view
Apache Solr before 5.1 mishandled crafted fields while rendering the Admin UI Analysis and Schema-Browser pages, tied to analysis.js and schema-browser.js. The documented vulnerability class is XSS, but the supplied metadata lacks CVSS, CWE, complete affected product records, and detailed vendor remediation text.
Likely exposure
Exposure is most likely in legacy Apache Solr deployments earlier than 5.1 where the Admin UI is reachable by untrusted users, semi-trusted users, or the internet. The bundle’s affected-product metadata is incomplete, so version and interface exposure checks are necessary.
Exploitation context
The source bundle does not show CISA KEV status or cited evidence of active exploitation. Practical risk depends on whether an attacker can place crafted fields that an administrator later views in the Analysis or Schema-Browser Admin UI pages.
Researcher notes
The evidence identifies two Admin UI rendering locations but does not include CVSS, CWE, affected CPEs, proof-of-concept status, or exploitation telemetry. Avoid assuming broader Solr components are affected without confirming against Apache’s SOLR-7346 record and local version data.
Mitigation direction
- Upgrade Apache Solr to 5.1 or later where feasible.
- Restrict Solr Admin UI access to trusted networks and administrators.
- Review Apache SOLR-7346 and current vendor guidance for fix details.
- Retire or isolate unsupported legacy Solr instances.
Validation and detection
- Inventory Apache Solr versions and flag deployments older than 5.1.
- Confirm the Solr Admin UI is not internet-exposed.
- Review access controls for users who can influence rendered admin fields.
- Check vulnerability scans for CVE-2015-8795 or Solr pre-5.1 findings.
