Detailsinfo

A vulnerability was found in Simple DNS Plus 9. It has been classified as problematic. Affected is an unknown function. The manipulation with an unknown input leads to a information disclosure vulnerability. CWE is classifying the issue as CWE-200. The product exposes sensitive information to an actor that is not explicitly authorized to have access to that information. This is going to have an impact on confidentiality. CVE summarizes:

Improper handling of DNS over TCP in Simple DNS Plus v9 allows a remote attacker with querying access to the DNS server to cause the server to return request payloads from other clients. This happens when the TCP length prefix is malformed (len differs from actual packet len), and due to a concurrency/buffering issue, even when the lengths match. A length prefix that is smaller than the actual packet size increases information leakage. In summary, this vulnerability allows an attacker to see DNS queries of other clients.

The advisory is shared for download at ma-personal.notion.site. This vulnerability is traded as CVE-2025-61430 since 09/26/2025. The exploitability is told to be easy.
