Title

Уязвимость сервера DNS BIND, связанная с неудачной проверкой утверждения, которая приводит к неполной очистке, позволяющая нарушителю выполнить атаку типа «отказ в обслуживании»

Description

Уязвимость сервера DNS BIND связана с достижимым утверждением при обработке DNS-запросов. Эксплуатация уязвимости позволяет нарушителю, действующему удаленно, отправлять повторяющиеся шаблоны определенных запросов на серверы с включенной функцией DNSSEC-Validated Cache (synth-from-dnssec) и вызывать ошибку INSIST в query.c:query_dname, что приводит к неожиданному завершению named

CVE-2022-0635 (GCVE-0-2022-0635)

Vulnerability from cvelistv5 – Published: 2022-03-23 11:55 – Updated: 2024-09-17 02:21

Summary

Versions affected: BIND 9.18.0 When a vulnerable version of named receives a series of specific queries, the named process will eventually terminate due to a failed assertion check.

Severity

7.5 (High)


                        
                          CVSS:3.1/AV:N/AC:L/PR:N/UI:N/S:U/C:N/I:N/A:H

CWE

We refactored the RFC 8198 Aggressive Use of DNSSEC-Validated Cache feature (synth-from-dnssec) for the new BIND 9.18.0 stable release, and changed the default so that is now automatically enabled for dnssec-validating resolvers. Subsequently it was found that repeated patterns of specific queries to servers with this feature enabled could cause an INSIST failure in query.c:query_dname which causes named to terminate unexpectedly. The vulnerability affects BIND resolvers running 9.18.0 that have both dnssec-validation and synth-from-dnssec enabled. (Note that dnssec-validation auto; is the default setting unless configured otherwise in named.conf and that enabling dnssec-validation automatically enables synth-from-dnssec unless explicitly disabled) Versions affected: BIND 9.18.0

The vulnerability affects BIND resolvers running 9.18.0 that have both dnssec-validation and synth-from-dnssec enabled. (Note that dnssec-validation auto; is the default setting unless configured otherwise in named.conf and that enabling dnssec-validation automatically enables synth-from-dnssec unless explicitly disabled) Versions affected: BIND 9.18.0"

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.
