CriticalCVSS 9.3Exploitation Probability (EPSS)
Low risk8th percentile - higher than 8% of all known CVEs
Summary
GeoVision GV-IP Device Utility 9.0.5 sends privileged commands via UDP broadcast, encrypting credentials with a Blowfish-like algorithm, but the symmetric key is included in the packet. An attacker on the same LAN can capture broadcast traffic and decrypt the credentials.
Risk Assessment
Compromise of device administrator credentials allows full control over device configuration, including changing the IP address or resetting to factory defaults. The risk affects organizations using this utility on networks accessible to unauthorized parties.
Recommendation
Update GeoVision GV-IP Device Utility to a non-vulnerable version or restrict access to the network where the utility operates. Consider network segmentation and monitoring broadcast traffic for suspicious packets.

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.
- CVE-2026-16519High
The GeoVision GV-IP Device Utility desktop application is vulnerable to DLL hijacking. It loads DLLs from an unsafe search path, allowing a local attacker to place a malicious DLL in a location searched before the legitimate library.
Original NVD description (English source)
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.
