Security readout for executives and security teams
Plain-English summary
FreshDNS 1.0.3 and earlier allowed a logged-in user’s browser to be tricked into making unwanted DNS management changes. If an administrator visited a malicious website while authenticated, domains or zones could be edited using that administrator’s privileges. The bundle says this was fixed in 1.0.5 and later.
Executive priority
Treat as a targeted operational risk. Prioritize remediation if FreshDNS manages production DNS, because unauthorized zone edits can affect availability, trust, and traffic routing.
Technical view
CVE-2018-1000846 is a CSRF flaw affecting authenticated FreshDNS API calls in index.php and class.manager.php. The documented impact is editing domains and zones with the victim’s privileges. Exploitation requires the victim to open a website containing attacker-controlled JavaScript. No CVSS, CWE, or KEV evidence is provided.
Likely exposure
Exposure is likely limited to organizations running FreshDNS 1.0.3 or earlier, particularly where administrators access the interface from browsers that also browse untrusted sites.
Exploitation context
The source bundle does not show active exploitation or inclusion in CISA KEV. The described scenario requires user interaction and an already authenticated victim, but the resulting DNS zone or domain changes could disrupt services or redirect traffic.
Researcher notes
Evidence is sparse: the CVE record names affected versions, components, impact, interaction requirement, and fixed version, but provides no CVSS vector or public exploitation evidence. Avoid broad product assumptions beyond FreshDNS 1.0.3 and earlier.
Mitigation direction
- Upgrade FreshDNS to version 1.0.5 or later.
- Review the linked vendor issue and commit for fix context.
- Restrict access to FreshDNS administration interfaces.
- Review recent domain and zone changes for unauthorized edits.
Validation and detection
- Inventory FreshDNS deployments and record installed versions.
- Confirm all instances are running 1.0.5 or later.
- Check DNS management logs for unexpected authenticated changes.
- Verify authenticated state-changing requests include CSRF protections.
