Our research reveals two significant vulnerabilities in Microsoft Azure Private 5G Core (AP5GC). The first vulnerability (CVE-2024-20685) allows a crafted signaling message to crash the control plane, leading to potential service outages. The second (ZDI-CAN-23960) disconnects and replaces attached base stations, disrupting network operations. While these issues are implementation-specific, their exploitation is made possible by a systemic weakness: the lack of mandatory authentication procedures between base stations and packet-cores.

Security Researcher Uncovered the Flaw, Which Allowed System TakeoverMicrosoft says it fixed a security flaw in artificial intelligence chatbot Copilot that enabled attackers to steal multifactor authentication code using a prompt injection attack. Security researcher Johann Rehberger said he discovered a way to invisibly force Copilot to send data.
