Traffic interception via shared private keys
Published Jun 12, 2020 · Updated Sep 17, 2024
Shared cryptographic key weakness in GeoVision Door Access Control devices through listed firmware allows remote attackers to intercept SSH and HTTPS traffic. Firmware embeds identical private keys for SSH and HTTPS across multiple device models, enabling man-in-the-middle decryption and plaintext recovery of protected messages. Attackers must be positioned on the communication path; the documented consequence is confidentiality loss without stated ability to alter device data or interrupt service.
