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: - использование облачных служб и адаптивной аутентификации Citrix; - использование средств межсетевого экранирования для ограничения возможности удалённого доступа; - ограничить время и возможность нахождения устройства в уязвимых режимах работы (виртуальный сервер VPN, прокси-сервер ICA, CVPN, прокси-сервер RDP, виртуальный сервер AAA); - использование виртуальных частных сетей для организации удаленного доступа (VPN).

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.
