CVE-2025-14651 identifies a vulnerability in MartialBE one-hub, a software product used for collaborative or hub services, affecting all versions up to 0.14.27. The vulnerability is due to the use of a hard-coded cryptographic key specified in the docker-compose.yml file, particularly the SESSION_SECRET environment variable. This secret is intended to secure session management or cryptographic operations but is fixed and publicly known in the default configuration, making it predictable. Attackers can remotely exploit this flaw by leveraging the known SESSION_SECRET to potentially decrypt or forge session tokens, leading to unauthorized access or data exposure. The attack complexity is high, indicating that exploitation requires significant effort or conditions, and no privileges or user interaction are needed. The vulnerability does not affect integrity or availability directly but impacts confidentiality by exposing cryptographic secrets. The vendor explicitly states that the default docker-compose example is not suitable for production and recommends users to customize all configurations and environment variables. No patches or fixes are currently linked, so mitigation relies on configuration changes. No known exploits are reported in the wild, but public disclosure increases risk. The CVSS 4.0 score is 6.3 (medium), reflecting network attack vector, high complexity, no privileges or user interaction, and limited confidentiality impact. This vulnerability highlights the risks of deploying default configurations with embedded secrets in containerized environments.

For European organizations, this vulnerability poses a risk of unauthorized access to sensitive session data or cryptographic operations if MartialBE one-hub is deployed using default configurations. Confidentiality breaches could lead to exposure of user data or internal communications, undermining trust and compliance with GDPR and other data protection regulations. Although the attack complexity is high, skilled attackers targeting organizations with valuable data or critical infrastructure could exploit this vulnerability remotely without authentication. This could facilitate lateral movement or privilege escalation in broader attack campaigns. The impact is particularly significant for sectors relying on secure collaboration platforms, such as finance, healthcare, and government agencies. Additionally, the use of container orchestration and default environment variables is common in DevOps pipelines, increasing the likelihood of misconfiguration. Failure to address this vulnerability could result in regulatory penalties, reputational damage, and operational disruptions.

European organizations should immediately audit all MartialBE one-hub deployments to identify usage of default docker-compose.yml files and the SESSION_SECRET environment variable. Replace the hard-coded SESSION_SECRET with a securely generated, high-entropy secret unique to each deployment. Implement secrets management best practices, such as using vault solutions or environment-specific secret injection mechanisms rather than embedding secrets in code or configuration files. Review and harden all environment variables and configuration settings before production deployment. Monitor network traffic for anomalous access patterns targeting the one-hub service. Apply network segmentation and firewall rules to restrict access to the one-hub service to trusted internal networks. Engage with MartialBE for updates or patches addressing this issue and subscribe to vendor advisories. Conduct regular security training for DevOps and infrastructure teams to prevent deployment of insecure default configurations. Finally, integrate configuration scanning tools into CI/CD pipelines to detect hard-coded secrets automatically.
