Security readout for executives and security teams

Plain-English summary

CVE-2018-1000847 is a stored cross-site scripting issue in FreshDNS 1.0.3 and earlier. A malicious account profile value could run JavaScript when an administrator views the user list, potentially affecting the administrator's session.

Executive priority

Treat this as a targeted application risk, not an emergency. Prioritize remediation if FreshDNS is internet-facing, multi-user, or administered from privileged browser sessions.

Technical view

The CVE describes stored XSS in FreshDNS account data, including the Full Name field, surfaced through the admin User List and related zone editor context. The record states the issue appears fixed in version 1.0.5 and later.

Likely exposure

Exposure is likely limited to organizations running FreshDNS 1.0.3 or earlier, especially instances where untrusted users can create or edit account profile data viewed by administrators.

Exploitation context

The source bundle describes a stored XSS path but provides no CVSS score and no KEV listing. The provided evidence does not show active exploitation in the wild.

Researcher notes

The public record lacks CVSS, CWE, and detailed affected CPE metadata. Analysis should stay tied to FreshDNS 1.0.3 and earlier, the account data form, and the upstream GitHub issue and commit.

Mitigation direction

  • Upgrade FreshDNS to version 1.0.5 or later.
  • Review the upstream issue and fix commit before planning remediation.
  • Restrict admin interface access to trusted administrators.
  • Check vendor guidance if maintaining a fork or backport.

Validation and detection

  • Inventory FreshDNS deployments and record exact versions.
  • Confirm any running instance is version 1.0.5 or later.
  • Review user profile fields for unexpected script-like content.
  • Verify admin user-list views encode account-supplied data.
