CVSS: 4.3EPSS: 0%CPEs: 9EXPL: 1CVE-2020-25686 – dnsmasq: multiple queries forwarded for the same name makes forging replies easier for an off-path attacker
https://notcve.org/view.php?id=CVE-2020-25686
19 Jan 2021 — A flaw was found in dnsmasq before version 2.83. When receiving a query, dnsmasq does not check for an existing pending request for the same name and forwards a new request. By default, a maximum of 150 pending queries can be sent to upstream servers, so there can be at most 150 queries for the same name. This flaw allows an off-path attacker on the network to substantially reduce the number of attempts that it would have to perform to forge a reply and have it accepted by dnsmasq. This issue is mentioned i... • https://github.com/knqyf263/dnspooq • CWE-290: Authentication Bypass by Spoofing CWE-358: Improperly Implemented Security Check for Standard •
