This failure could allow an attacker to provide a malicious update and alter the functionality of Rapid7 Nexpose. The attacker would need some pre-existing mechanism to provide a malicious update, either through a social engineering effort, privileged access to replace downloaded updates in transit, or by performing an Attacker-in-the-Middle attack on the update service itself.","cvss_v4":null,"cvss_v3":{"version":"3.1","vector":"CVSS:3.1/AV:N/AC:L/PR:L/UI:N/S:U/C:N/I:H/A:N","score":6.5},"cwes":["CWE-494"],"references":["https://docs.rapid7.com/release-notes/insightvm/20221207/","https://docs.rapid7.com/release-notes/nexpose/20221207/","https://www.rapid7.com/blog/post/2022/12/7/cve-2022-4261-rapid7-nexpose-update-validation-issue-fixed","https://docs.rapid7.com/release-notes/insightvm/20221207/","https://docs.rapid7.com/release-notes/nexpose/20221207/"],"products":["rapid7:insightvm","rapid7:nexpose"],"source":"nvd","synced_at":"2026-10-19T21:37:28.463369388+00:00"},"epss":{"cve":"CVE-2022-4261","score":0.00323,"percentile":0.25381,"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).
