CVE-2025-71058
Dual DHCP DNS Server 8.01 can accept any UDP DNS response and cache it without checking the source. This allows a remote attacker to inject fake DNS records into the server’s cache, potentially redirecting users to malicious sites.
No official fix yet. If none appears within 45 days of first tracking, this entry is removed automatically.
Who is affected
Dual DHCP DNS Server version 8.01, used by network administrators to provide DNS services.
Real-world impact
An attacker could poison the DNS cache of the server, causing users to be redirected to attacker‑controlled destinations or to intercept traffic.
Why this severity
The CVSS score of 9.1 reflects that the flaw is exploitable over the network, requires no user interaction or special privileges, and can compromise both integrity and availability of the DNS service.
What to do about it
No official fix or mitigation is documented in the sources yet. Monitor the vendor advisory and apply the patch as soon as it is released.
