{"cve":"CVE-2018-11804","nvd":{"published":"2018-10-24T18:29:00.263","modified":"2026-06-17T01:36:37.953","status":"Modified","description":"Spark's Apache Maven-based build includes a convenience script, 'build/mvn', that downloads and runs a zinc server to speed up compilation. It has been included in release branches since 1.3.x, up to and including master. This server will accept connections from external hosts by default. A specially-crafted request to the zinc server could cause it to reveal information in files readable to the developer account running the build. Note that this issue does not affect end users of Spark, only developers building Spark from source code.","cvss_v4":null,"cvss_v3":{"version":"3.1","vector":"CVSS:3.1/AV:N/AC:L/PR:N/UI:N/S:U/C:H/I:N/A:N","score":7.5},"cwes":[],"references":["http://www.securityfocus.com/bid/105756","https://lists.apache.org/thread.html/2b11aa4201e36f2ec8f728e722fe33758410f07784379cbefd0bda9d%40%3Cdev.spark.apache.org%3E","https://spark.apache.org/security.html#CVE-2018-11804","http://www.securityfocus.com/bid/105756","https://lists.apache.org/thread.html/2b11aa4201e36f2ec8f728e722fe33758410f07784379cbefd0bda9d%40%3Cdev.spark.apache.org%3E"],"products":["apache:spark"],"source":"nvd","synced_at":"2026-10-19T20:53:59.789560037+00:00"},"epss":{"cve":"CVE-2018-11804","score":0.05696,"percentile":0.93007,"date":"2026-10-31"},"kev":null,"osv":[{"id":"GHSA-62g2-m955-v383","url":"https://osv.dev/vulnerability/GHSA-62g2-m955-v383","summary":"Improper Input Validation in Apache Spark","modified":"2025-12-11T20:58:56.204203Z","packages":[{"ecosystem":"Maven","name":"org.apache.spark:spark-core_2.11","purl":"pkg:maven/org.apache.spark/spark-core_2.11","ranges":[">=1.3.0 <=2.1.3"],"fixed":[]},{"ecosystem":"Maven","name":"org.apache.spark:spark-core_2.10","purl":"pkg:maven/org.apache.spark/spark-core_2.10","ranges":[">=1.3.0 <=2.1.3"],"fixed":[]}]}],"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).
