CVE-2024-42418Network attack vector

Sensitive-information decryption via default cryptographic key

Published Aug 22, 2024 · Updated Aug 22, 2024

Hard-coded key use in Avtec Outpost 0810 and Outpost Uploader Utility before 5.0.0 allows remote attackers to decrypt sensitive information. CISA identifies a default cryptographic key but does not disclose the protected data, cryptographic routine, or request that exposes ciphertext. The network path requires no authentication or user interaction, and the reported consequence is confidentiality loss without data modification or service interruption.
