On affected versions of the Arista CloudVision Portal (CVP on-prem), the time-bound device onboarding token can be used to gain admin privileges on CloudVision.
On Arista CloudVision systems (virtual or physical on-premise deployments), Zero Touch Provisioning can be used to gain admin privileges on the CloudVision system, with more permissions than necessary, which can be used to query or manipulate system state for devices under management. Note that CloudVision as-a-Service is not affected.
On affected versions of the CloudVision Portal, improper access controls could enable a malicious authenticated user to take broader actions on managed EOS devices than intended. This advisory impacts the Arista CloudVision Portal products when run on-premise. It does not impact CloudVision as-a-Service.
On Arista CloudVision Appliance (CVA) affected releases running on appliances that support hardware disk encryption (DCA-350E-CV only), the disk encryption might not be successfully performed. This results in the disks remaining unsecured and data on them
On affected versions of the CloudVision Portal improper access controls on the connection from devices to CloudVision could enable a malicious actor with network access to CloudVision to get broader access to telemetry and configuration data within the system than intended. This advisory impacts the Arista CloudVision Portal product when run on-premise. It does not impact CloudVision as-a-Service.
Arista CloudVision Portal through 2018.1.1 has Incorrect Permissions.
In CloudVision Portal (CVP) for all releases in the 2018.2 Train, under certain conditions, the application logs user passwords in plain text for certain API calls, potentially leading to user password exposure. This only affects CVP environments where: 1. Devices have enable mode passwords which are different from the user's login password, OR 2. There are configlet builders that use the Device class and specify username and password explicitly Application logs are not accessible or visible from the CVP GUI. Application logs can only be read by authorized users with privileged access to the VM hosting the CVP application.
In CloudVision Portal all releases in the 2018.1 and 2018.2 Code train allows users with read-only permissions to bypass permissions for restricted functionality via CVP API calls through the Configlet Builder modules. This vulnerability can potentially enable authenticated users with read-only access to take actions that are otherwise restricted in the GUI.
A vulnerability in Arista’s CloudVision Portal (CVP) prior to 2020.2 allows users with “read-only” or greater access rights to the Configlet Management module to download files not intended for access, located on the CVP server, by accessing a specific API.
In support.c in pamtacplus 1.3.8 through 1.5.1, the TACACS+ shared secret gets logged via syslog if the DEBUG loglevel and journald are used.
Arista’s CloudVision eXchange (CVX) server before 4.21.12M, 4.22.x before 4.22.7M, 4.23.x before 4.23.5M, and 4.24.x before 4.24.2F allows remote attackers to cause a denial of service (crash and restart) in the ControllerOob agent via a malformed control-plane packet.
