Mitigations

Использование рекомендаций: https://my.f5.com/manage/s/article/K000136907 Компенсирующие меры: Рекомендуется отключить трафик локальной подсети в профиле доступа к сети BIG-IP APM. В результате весь трафик, кроме трафика виртуального сервера, будет проходить через VPN-туннель. Для этого выполните следующую процедуру: 1. Войдите в систему BIG-IP APM как администратор; 2. Откройте «Access» > «Connectivity / VPN» > «Network Access (VPN)» > «Network Access Lists»; 3. Выберите «Network Access Profile» для настройки; 4. Выберите вкладку «Network Settings»; 5. В разделе «Client Settings» выберите «Advanced» из списка; 6. Снимите флажок «Allow Local Subnet»; 7. В разделе «Traffic Options» выберите «Force all traffic through tunnel»; 8. Выберите «Update».

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.
