CVE-2025-34025:
Versa concerto vulnerability analysis and mitigation

Overview

The Versa Concerto SD-WAN orchestration platform contains a critical privilege escalation and container escape vulnerability (CVE-2025-34025) that affects versions 12.1.2 through 12.2.0. The vulnerability is caused by unsafe default mounting of host binary paths that allow the container to modify host paths, enabling container escape and potential remote code execution or direct host access depending on the host operating system configuration (NVD, Project Discovery).

Technical details

The vulnerability stems from a critical misconfiguration where the core-service docker container has /usr/bin/ and /bin/ directories directly mapped to the host's filesystem. This allows any changes made to binaries within the container to affect the host system. The vulnerability has been assigned a CVSS v4.0 score of 8.6 (HIGH) with the vector string CVSS:4.0/AV:L/AC:L/AT:P/PR:H/UI:N/VC:H/VI:H/VA:L/SC:H/SI:H/SA:L (NVD, Project Discovery).

Impact

The vulnerability allows attackers to escape from the container environment and gain execution privileges on the host machine. By exploiting the misconfigured binary paths, attackers can overwrite system binaries with malicious code, potentially leading to complete system compromise. This can result in remote code execution or direct host access, depending on the host operating system configuration (Project Discovery, Hacker News).

Mitigation and workarounds

Versa Networks has addressed these issues in Concerto version 12.2.1 GA released on April 16, 2025. Organizations are strongly advised to upgrade to this version. For systems that cannot be immediately updated, it is recommended to monitor network traffic and logs for suspicious activity (Hacker News).

Community reactions

The vulnerability has gained significant attention in the cybersecurity community, with researchers and experts expressing concern about the potential impact on enterprise networks. Tenable has classified this as a 'Vulnerability Being Monitored' and is actively tracking potential exploitation attempts (Tenable).
