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 internal Actuator endpoint can be leveraged for access to heap dumps and trace logs.This issue is known to affect Concerto from 12.1.2 through 12.2.0. Additional versions may be vulnerable.

Summary dbcve.org

The Versa Concerto SD-WAN orchestration platform contains an authentication bypass vulnerability in its Traefik reverse proxy configuration. Attackers can bypass authentication controls to reach administrative endpoints, including the internal Spring Actuator interface which exposes sensitive information such as heap dumps and trace logs.

Mitigation

Configure Traefik to enforce authentication on all backend endpoints, particularly the Actuator endpoints. Disable or restrict access to sensitive Actuator endpoints (heapdump, trace, env, etc.) if not required for operations, or require strong authentication if needed.
