CVE-2022-2795 (GCVE-0-2022-2795)

Vulnerability from cvelistv5 – Published: 2022-09-21 10:15 – Updated: 2024-11-29 12:04

Title

Processing large delegations may severely degrade resolver performance

Summary

By flooding the target resolver with queries exploiting this flaw an attacker can significantly impair the resolver's performance, effectively denying legitimate clients access to the DNS resolution service.

Severity

5.3 (Medium)

CWE

In BIND 9.0.0 -> 9.16.32, 9.18.0 -> 9.18.6, versions 9.9.3-S1 -> 9.11.37-S1, 9.16.8-S1 -> 9.16.32-S1 of the BIND Supported Preview Edition, and versions 9.19.0 -> 9.19.4 of the BIND 9.19 development branch, a flaw in resolver code can cause named to spend excessive amounts of time on processing large delegations.

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.
