Software Name

Concerto

Software Version

от 12.1.0 до 12.2.0 включительно (Concerto)

Possible Mitigations

Компенсирующие меры: - необходимо реализовать правило, блокирующее все входящие запросы, содержащие символ точки с запятой ( ;) в пути URL. Данная мера направлена на предотвращение возможных атак, основанных на несоответствиях в декодировании URL, которые могут позволить злоумышленникам обойти механизмы аутентификации. - для минимизации риска несанкционированного доступа к конечным точкам Spring Boot Actuator, рекомендуется настроить обратный прокси-сервер или WAF (Web Application Firewall) таким образом, чтобы отклонять все входящие запросы, содержащие заголовок "Connection" с значением "X-Real-Ip" (без учета регистра). Данная мера позволит предотвратить эксплуатацию уязвимости, связанной с возможностью злоупотребления заголовком "X-Real-Ip" для обхода аутентификации и авторизации.

CVE-2025-34027 (GCVE-0-2025-34027)

Vulnerability from cvelistv5 – Published: 2025-05-21 21:58 – Updated: 2026-02-26 18:27

Title

Versa Concerto Authentication Bypass File Write Remote Code Execution

Summary

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 ?
