Produktbeschreibung: Der Domain Name Service (DNS) ermöglicht die Umsetzung der Domainnamen in IP-Adressen. Zur Verhinderung von übermäßigen Anfragen werden die Zuordnungen häufig lokal in einem Cache gespeichert.

Angriff: Ein entfernter, anonymer Angreifer kann eine Schwachstelle in PowerDNS ausnutzen, um einen Denial of Service Angriff durchzuführen.

Betroffene Betriebssysteme: - Linux

CVE-2024-25581

Es besteht eine Schwachstelle in PowerDNS. Dieser Fehler besteht im Prozess DNS over HTTPS aufgrund eines Assertion-Fehlers in DNSdist. Durch das Senden einer Anforderung für einen Zonentransfer über DNS über HTTPS kann ein entfernter, anonymer Angreifer diese Schwachstelle ausnutzen, um einen Denial-of-Service-Zustand zu verursachen.

CVE-2024-25581 (GCVE-0-2024-25581)

Vulnerability from cvelistv5 – Published: 2024-05-13 11:49 – Updated: 2025-02-13 17:40

Title

Transfer requests received over DoH can lead to a denial of service in DNSdist

Summary

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.

Severity

7.5 (High)

The MITRE ATT&CK techniques below are AI-generated suggestions, inferred from the description of the vulnerability by the CIRCL/vulnerability-attack-technique-classification-roberta-base model, served locally by ML-Gateway. They have not been verified by an analyst and are provided for guidance only.
The approach is described in our paper Mapping CVEs to MITRE ATT&CK Techniques: A Curated Gold-Set Classifier and the Limits of LLM-Assisted Label Expansion.

Related by attack behaviour

Vulnerabilities whose description is nearest to this one in the vector space of the CIRCL/vulnerability-attack-technique-biencoder model. This is a similarity search over the bi-encoder space (plain cosine), not a classification, and it has no measured accuracy.
