CVE-2025-1099

Key disclosure via hard-coded firmware private key

Published Feb 10, 2025 · Updated Feb 14, 2025

Hard-coded key storage in TP-Link Tapo C500 firmware allows physically proximate attackers to obtain embedded RSA private keys. The device firmware embeds an unchangeable RSA private key instead of protecting a device-specific secret outside the extractable image. Physical access to an affected V1 or V2 camera is required; the recovered key enables device impersonation, traffic decryption, and man-in-the-middle attacks.
