Technical details
The vulnerability stems from a permissive cross-domain policy that fails to properly validate or restrict access to untrusted domains within Azure Arc. An attacker with network access can exploit this configuration to bypass authentication mechanisms and escalate privileges. The vulnerability is remotely exploitable over the network without requiring prior authentication or user interaction. Successful exploitation grants an attacker elevated permissions that can be leveraged to compromise systems and data managed by Azure Arc. Microsoft has released security updates to address this issue.
