    CVE-2025-34027 – Versa Concerto Traefik Reverse Proxy Authentication Bypass and Remote Code Execution

    May 21, 2025

    CVE ID : CVE-2025-34027

    Published : May 21, 2025, 10:15 p.m. | 35 minutes ago

    Description : The Versa Concerto SD-WAN orchestration platform is vulnerable to an authentication bypass in the Traefik reverse proxy configuration, allowing at attacker to access administrative endpoints. The Spack upload endpoint can be leveraged for a Time-of-Check to Time-of-Use (TOCTOU) write in combination with a race condition to achieve remote code execution via path loading manipulation, allowing an unauthenticated actor to achieve remote code execution (RCE).This issue is known to affect Concerto from 12.1.2 through 12.2.0. Additional versions may be vulnerable.

    Severity: 0.0 | NA
