CVE-2026-7161
Official description Straight from the sourceThe vendor's or NVD's own wording, published unedited. Authoritative, but often terse — it says what broke, rarely what to do.
NVD · uneditedAn 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.
Technical summary Written by usOur analysis, written from the advisory, the CVSS vector and the affected-version data. It adds context the advisory leaves out, and never invents facts that are not in the source.
dbcve analysis · high confidenceThe GV-IP Device Utility 9.0.5 broadcasts privileged commands over UDP with username/password encrypted using a Blowfish-derived algorithm. However, the symmetric encryption key is included directly in the packet itself, making the encryption functionally useless since an attacker can extract the key from captured packets and trivially decrypt the credentials.

Am I affected? How to checkSteps we derive from the advisory and the affected-version data, so you can decide whether this CVE reaches your setup. They are a guide, not a scan — your own configuration is the authority.
dbcve checksWork through these to decide whether this CVE applies to you.
-
Verify GV-IP Device Utility versionOpen the application or check its About/Help menu to confirm the installed version number is 9.0.5Affected if Version displayed is exactly 9.0.5
-
Confirm UDP broadcast is enabledLaunch the GV-IP Device Utility and check if Device Discovery or broadcast functionality is configured to use UDP port broadcasting (typically port 4550 or 5550)Affected if UDP broadcast discovery is enabled and actively sending/receiving packets on the network
-
Capture and inspect broadcast packetsUse a network packet capture tool (such as Wireshark) on the same network segment and filter for UDP packets sent from the utility to the broadcast address, then examine the payload for both encrypted data and what appears to be a key componentAffected if Captured UDP broadcast packets contain both an encryption key and encrypted credentials in the same packet payload
A user is affected if they are running version 9.0.5 of the GeoVision GV-IP Device Utility and are using its UDP broadcast feature to discover or communicate with IP devices on the network.

Remediation Closing itWhat it takes to close this. Where a vendor fix exists we point at it; where none exists we say so plainly, and can build one. Effort estimates are scoped from the advisory, not from your codebase.
From vendor dataAvoid using the affected utility on untrusted networks; implement network segmentation to limit exposure to LAN-based attackers. Contact GeoVision for an updated utility version that implements proper encryption with out-of-band key exchange or TLS-based authentication.
