Mitigations

Установка обновлений из доверенных источников. В связи со сложившейся обстановкой и введенными санкциями против Российской Федерации рекомендуется устанавливать обновления программного обеспечения только после оценки всех сопутствующих рисков. Компенсирующие меры: - ограничение использования парсера HTTP/2; - использование сигнатур, где первый байт тестирует тип фрейма HTTP2 DATA, а второй тестирует идентификатор потока 0 (например, drop http2 any any -> any any (frame:http2.hdr; byte_test:1,=,0,3; byte_test:4,=,0,5; sid: 1;)); - использование средств межсетевого экранирования для ограничения возможности удалённого доступа к уязвимому программному обеспечению; - сегментирование сети для ограничения доступа к уязвимому программному обеспечению из других подсетей; - использование виртуальных частных сетей для организации удаленного доступа (VPN). Использование рекомендаций: Для Suricata: https://github.com/OISF/suricata/commit/1d6d331752e933c46aca0ae7a9679b27462246e3 https://github.com/OISF/suricata/commit/7fa88ea9e7d05e07a7864050cfd836b576669720 https://github.com/OISF/suricata/security/advisories/GHSA-qrr7-crgj-cmh3 Для Debian GNU/Linux: https://security-tracker.debian.org/tracker/CVE-2025-53538 Для Fedora: https://bugzilla.redhat.com/show_bug.cgi?id=CVE-2025-53538 Для Kaspersky Industrial CyberSecurity for Networks: следовать рекомендациям по повышению защищенности системы, изложенным в документации на программное изделие https://support.kaspersky.ru/kics-for-networks/4.5?page=main

CVE-2025-53538 (GCVE-0-2025-53538)

Vulnerability from cvelistv5 – Published: 2025-07-22 21:36 – Updated: 2025-07-23 18:32

Title

Suricata's mishandling of data on HTTP2 stream 0 can lead to resource starvation

Summary

Suricata is a network IDS, IPS and NSM engine developed by the OISF (Open Information Security Foundation) and the Suricata community. In versions 7.0.10 and below and 8.0.0-beta1 through 8.0.0-rc1, mishandling of data on HTTP2 stream 0 can lead to uncontrolled memory usage, leading to loss of visibility. Workarounds include disabling the HTTP/2 parser, and using a signature like drop http2 any any -> any any (frame:http2.hdr; byte_test:1,=,0,3; byte_test:4,=,0,5; sid: 1;) where the first byte test tests the HTTP2 frame type DATA and the second tests the stream id 0. This is fixed in versions 7.0.11 and 8.0.0.

In versions 7.0.10 and below and  8.0.0-beta1 through 8.0.0-rc1, mishandling of data on HTTP2 stream 0 can lead to uncontrolled memory usage, leading to loss of visibility. Workarounds include disabling the HTTP/2 parser, and using a signature like drop http2 any any -\u003e any any (frame:http2.hdr; byte_test:1,=,0,3; byte_test:4,=,0,5; sid: 1;) where the first byte test tests the HTTP2 frame type DATA and the second tests the stream id 0. This is fixed in versions 7.0.11 and 8.0.0."

Detection rules are retrieved from Rulezet.

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.
