Credential disclosure via transmitted Blowfish key
Published May 4, 2026 · Updated May 4, 2026
Insufficient encryption in GeoVision GV-IP Device Utility 9.0.5 allows attackers to recover device credentials via LAN sniffing. The encrypt_username_and_password_to_pkt function encrypts the username and password with Blowfish, then places both ciphertext and the symmetric key in the same UDP broadcast packet. Exploitation requires the same LAN and an administrator action that emits a privileged command; recovered credentials grant device-configuration control, including address changes and factory reset.

Exploitability
Present is not the same as exploitable
Compare your product and version with the public record. A matching version still requires validation against your environment.
Is a vulnerable build present?
Compare these published version ranges with your installed build and any vendor patches.
