{"cve":"CVE-2017-7678","nvd":{"published":"2017-07-12T13:29:00.267","modified":"2026-06-17T01:24:57.880","status":"Modified","description":"In Apache Spark before 2.2.0, it is possible for an attacker to take advantage of a user's trust in the server to trick them into visiting a link that points to a shared Spark cluster and submits data including MHTML to the Spark master, or history server. This data, which could contain a script, would then be reflected back to the user and could be evaluated and executed by MS Windows-based clients. It is not an attack on Spark itself, but on the user, who may then execute the script inadvertently when viewing elements of the Spark web UIs.","cvss_v4":null,"cvss_v3":{"version":"3.0","vector":"CVSS:3.0/AV:N/AC:L/PR:N/UI:R/S:C/C:L/I:L/A:N","score":6.1},"cwes":["CWE-79"],"references":["http://apache-spark-developers-list.1001551.n3.nabble.com/CVE-2017-7678-Apache-Spark-XSS-web-UI-MHTML-vulnerability-td21947.html","http://www.securityfocus.com/bid/99603","http://apache-spark-developers-list.1001551.n3.nabble.com/CVE-2017-7678-Apache-Spark-XSS-web-UI-MHTML-vulnerability-td21947.html","http://www.securityfocus.com/bid/99603"],"products":["apache:spark"],"source":"nvd","synced_at":"2026-10-19T20:43:44.556243339+00:00"},"epss":{"cve":"CVE-2017-7678","score":0.0338,"percentile":0.88781,"date":"2026-10-31"},"kev":null,"osv":[{"id":"GHSA-r34r-f84j-5x4x","url":"https://osv.dev/vulnerability/GHSA-r34r-f84j-5x4x","summary":"Moderate severity vulnerability that affects org.apache.spark:spark-core_2.10 and org.apache.spark:spark-core_2.11","modified":"2023-11-08T03:59:26.465744Z","packages":[{"ecosystem":"Maven","name":"org.apache.spark:spark-core_2.11","purl":"pkg:maven/org.apache.spark/spark-core_2.11","ranges":["<2.2.0"],"fixed":["2.2.0"]},{"ecosystem":"Maven","name":"org.apache.spark:spark-core_2.10","purl":"pkg:maven/org.apache.spark/spark-core_2.10","ranges":["<2.2.0"],"fixed":["2.2.0"]}]}],"attribution":["This product uses the NVD API but is not endorsed or certified by the NVD.","EPSS scores: FIRST Exploit Prediction Scoring System, https://www.first.org/epss","Known exploited vulnerabilities: CISA Known Exploited Vulnerabilities Catalog, https://www.cisa.gov/known-exploited-vulnerabilities-catalog","Package advisories: OSV (https://osv.dev), from the GitHub Advisory Database, PyPA, Go, RustSec and other ecosystem databases, under CC-BY 4.0 or CC0","CVE records: the CVE Program's CVE List (https://www.cve.org), under its terms of use (https://www.cve.org/Legal/TermsOfUse).
