What happened

An insufficient encryption vulnerability exists in the Device Authentication functionality of GeoVision GV-IP Device Utility 9.0.5. Listening to broadcast packets can lead to credentials leak. An attacker can listen to broadcast messages to trigger this vulnerability.

When interacting with various Geovision devices on the network, the utility may send privileged commands; in order to do so, the username and password of the device need to be provided. In some instances the command is broadcasted over UDP and the username/password are encrypted using a cryptographic protocol that appears to be derivated from Blowfish.

However the symmetric key used for the encryption is also included in the packet, and thus the security of the username/password only relies on the "obscurity" of the encryption scheme. An attacker on the same LAN can listen to the broadcast traffic once an admin user interacts with the device, and decrypt the credentials using their own implementation of the algorithm.

With this password the attacker would have full control over the device configuration, allowing them to change its ip address or even reset it to factory default.

An insufficient encryption vulnerability exists in the Device Authentication functionality of GeoVision GV-IP Device Utility 9.0.5. Listening to broadcast packets can lead to credentials leak. An attacker can listen to broadcast messages to trigger this vulnerability.

About this data

This record was ingested from a data source. Retrieved: Oct 27, 2026, 01:40 UTC. Ingestion is not an independent editorial investigation.

NVD status: Modified. Publication in the NVD is not evidence of exploitation.

A CISA KEV listing documents known exploitation, not necessarily a zero-day; absence from the catalog does not prove a vulnerability has never been exploited.

Technology tags indicate possible relevance, not verified exposure. Confirm the affected product, version, and configuration against your own inventory; KEVWire does not scan your systems.

A personal reading checklist on this device, not verified remediation.
