Technical details
A use-after-free vulnerability exists in Microsoft Active Directory Domain Services that can be exploited by an authorized network attacker to achieve remote code execution. The vulnerability requires prior authentication to the system. An attacker with valid credentials can craft a malicious network request that triggers the use-after-free condition, leading to arbitrary code execution in the context of the ADDS service. This could allow an authenticated attacker to escalate privileges, compromise domain controllers, or propagate laterally throughout an Active Directory environment.
