CVE-2024-49126 is a critical remote code execution vulnerability in the Windows Local Security Authority Subsystem Service (LSASS). LSASS is responsible for enforcing local security policy, handling authentication-related operations, processing password changes, and creating access tokens. The vulnerability is reachable over the network and can be exploited by an unauthenticated attacker using specially crafted network calls. Available reporting indicates exploitation requires winning a race condition, after which arbitrary code may be executed in the context of the server account. The issue affects the LSASS service rather than requiring local execution, making it a high-impact network-reachable flaw in a core Windows security component.
