CVE-2024-25581
Last modified
CVE-2024-25581 is a high-severity vulnerability rated 7.5/10 on the CVSS scale. When incoming DNS over HTTPS support is enabled using the nghttp2 provider, and queries are routed to a tcp-only or DNS over TLS backend, an attacker can trigger an assertion failure in DNSdist by sending a request for a zone transfer (AXFR or IXFR) over DNS over HTTPS, causing the process to stop and thus leading to a Denial of Service. DNS over HTTPS is not enabled by default, and backends are using plain DNS (Do53) by default.. EPSS estimates a 1.08% chance of exploitation in the next 30 days.
