VeloCloud Edge Unauthorized Software Installation via Weak Signature Validation

Publication date: 2026-09-16

Last updated on: 2026-09-16

Assigner: Arista Networks, Inc.

Description
The VeloCloud Edge software update workflow may accept update bundles without properly validating their signatures because the workflow does not restrict the digest algorithm used for artifact verification. An attacker with either sufficient privileges to upload packages to VeloCloud Orchestrator or credentials permitting direct access to an Edge may be able to install unauthorized software.

Executive Summary

This vulnerability involves the VeloCloud Edge software update process failing to validate the cryptographic signatures of update bundles properly. It allows attackers with sufficient privileges or direct access to install unauthorized software by exploiting weak digest algorithm restrictions during verification.

Impact Analysis

An attacker could exploit this to install malicious software on affected systems, potentially leading to unauthorized access, data breaches, or system compromise. This may disrupt operations or expose sensitive information.

Compliance Impact

This vulnerability could lead to unauthorized software installation, potentially violating compliance requirements for data protection and integrity. It may result in non-compliance with GDPR, HIPAA, or other standards due to increased risk of data exposure or system compromise.

Mitigation Strategies

Restrict privileges for uploading packages to VeloCloud Orchestrator and ensure direct Edge access requires strong authentication. Verify all update bundles use approved digest algorithms before installation.
