NOTE: since rsync is not setuid, this issue does not provide any additional privileges beyond those that are already available to the user.  Therefore this issue may be REJECTED in the future.","cvss_v4":null,"cvss_v3":null,"cwes":[],"references":["http://archives.neohapsis.com/archives/vuln-dev/2004-q1/0091.html","https://exchange.xforce.ibmcloud.com/vulnerabilities/15108","http://archives.neohapsis.com/archives/vuln-dev/2004-q1/0091.html","https://exchange.xforce.ibmcloud.com/vulnerabilities/15108"],"products":[],"source":"nvd","synced_at":"2026-10-19T19:37:11.487553034+00:00"},"epss":{"cve":"CVE-2004-2093","score":0.00998,"percentile":0.62755,"date":"2026-10-31"},"kev":null,"osv":[],"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).
