Apply mitigations in accordance with vendor instructions, ensuring compliance with CISA’s BOD 26-04 Prioritizing Security Updates Based on Risk (see URL in Notes) guidance and CISA’s “Forensics Triage Requirements” (see URL in Notes). Follow applicable BOD 26-04 guidance for cloud services or discontinue use of the product if mitigations are unavailable. Stakeholders are responsible for evaluating each asset's internet exposure and ensuring adherence to BOD 26-04 patching guidelines.
En resumen
Una vulnerabilidad en la configuración de OAuth del F5 BIG-IP APM permite que atacantes ejecuten código malicioso remotamente sin autenticación, comprometiendo potencialmente todo el sistema.
Detalle técnico
Cuando se habilitan políticas de acceso de BIG-IP APM y perfiles OAuth en un servidor virtual, atacantes no autenticados pueden enviar tráfico malicioso específico para lograr ejecución remota de código en el plano de datos.
Resumen generado y traducido por IA a partir de la descripción oficial.
When a BIG-IP APM access policy and an OAuth profile are configured on a virtual server, specific malicious traffic can lead to remote code execution (RCE). This vulnerability is only present when BIG-IP APM is configured as an OAuth Authorization Server. Deployments using APM strictly as an OAuth Client / Resource Server (without OAuth authorization server profiles configured) are not affected by this vulnerability.
Impact:
This vulnerability allows an unauthenticated attacker to perform remote code execution. The BIG-IP system in Appliance mode is also vulnerable. This is a data plane issue; there is no control plane exposure.
Note: Software versions which have reached End of Technical Support (EoTS) are not evaluated.
