Authenticated confidential-data exposure over adjacent networks
Published Oct 31, 2025 · Updated Feb 22, 2026
Authentication bypass in Microsoft Configuration Manager 2403 and 2409 allows remote authenticated users to expose confidential data over an adjacent network. Microsoft has not disclosed the affected request path, credential-validation error, or spoofed identity operation. Exploitation requires low privileges, an adjacent-network position, and high complexity; successful attacks expose confidential data without reported modification or service interruption.
