Unauthenticated privilege escalation via out-of-bounds read
Published Sep 10, 2024 · Updated Aug 10, 2026
Out-of-bounds read in Microsoft Windows Remote Access Connection Manager allows remote attackers to elevate privileges over a network. Microsoft has not published the named code locus or the invalid boundary operation that causes the out-of-bounds read. No authentication or user interaction is required, and successful exploitation allows privilege elevation with loss of confidentiality, integrity, and availability.
