CVE-2025-4876Known exploitationPublic exploit

Credential disclosure via plaintext AES key

Published May 19, 2025 · Updated Sep 3, 2025

Hard-coded key exposure in ConnectWise Risk Assessment versions prior to its July 2023 deprecation allows local users to decrypt scan credentials. The main.EncryptAES function loads a plaintext key from DAT_00585430 immediately before crypto/aes.NewCipher initializes the AES cipher. High-privilege access to both the executable and encrypted CSV input files exposes cleartext domain administrative credentials.
