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.
Given the criticality of this vulnerability, organizations must prioritize patching immediately.
Vulnerability Details
The CVSS score for this vulnerability is 9.3, classified as critical, indicating severe potential impact. The attack vector is network-based, requiring low attack complexity, no privileges, and user interaction. The scope is changed, with high confidentiality and availability impact.
The vulnerability is categorized under CWE-656, which relates to insufficient encryption.
Technical Analysis
The root cause of this vulnerability lies in the improper handling of encryption keys within the broadcast packets. By including the symmetric key with the encrypted credentials, the security relies solely on the obscurity of the encryption method. Attackers can exploit this flaw by eavesdropping on the network traffic.
The attack vector is network-based, as the utility sends sensitive information over UDP. The attack complexity is low since no special privileges are required, and user interaction is necessary when an admin interacts with the device.
Risk & Impact Analysis
Risk to organizations includes unauthorized access to device configurations, which can lead to potential service disruptions or complete loss of control over critical infrastructure. The urgency is high due to the critical nature of the CVSS score and the potential for exploitation in environments where the utility is deployed.
Organizations should address this vulnerability in their priority patch cycle, as attackers could exploit it to gain significant control over devices on the network.
