Arista CloudVision CUE: OS command injection in backup management
Summary
An authenticated Super User of Arista CloudVision CUE can submit a crafted backup request that injects OS commands. Arbitrary commands then run with the privileges of the affected service. Arista lists the on-premises deployment as affected; the vulnerability only applies when the CV-CUE backend (wifimanager) is enabled and running.
Affected
- CloudVision CUE 2021.2.0 to 2026.2.0 (on-premises)
- Default configuration: unaffected
- Vulnerable only if the CV-CUE backend (wifimanager) is enabled and running
Fixed in
- 2026.2.1 and later releases
- No backports to older release trains are named by Arista; ask Arista support for older versions. 2026.2 is listed as the final supported on-premises release.
Workaround
- Arista states that no mitigation or workaround is available.
Exploitation
- CISA SSVC: exploitation none, not automatable, total technical impact.
- Not listed in CISA KEV.
- No public proof-of-concept or exploitation in the wild known so far.
Our recommendation
- Identify all on-premises CloudVision Portal or CV-CUE deployments and their versions.
- Plan the upgrade to 2026.2.1 or later, prioritising internet-reachable systems, together with the fixes for CVE-2026-102159 in the same advisory.
- Until patched, restrict Super User accounts, review administrator accounts and block external access to the management interface.
- Monitor for unusual backup requests or new processes on the appliance.
Public exploits
PoC-in-GitHub, Metasploit and Exploit-DB list nothing for this CVE.
