CVE-2021-38388 is a high-severity vulnerability affecting version 0.51.1 of Central Dogma, a configuration and version control system developed by LINE Corporation. The vulnerability allows an attacker with limited privileges (PR:L) to escalate their privileges by exploiting the mirroring functionality to the internal Dogma repository. This internal repository contains a file responsible for managing project authorization, and unauthorized manipulation or access to this file can lead to privilege escalation. The vulnerability is remotely exploitable (AV:N) without requiring user interaction (UI:N), making it particularly dangerous. The CVSS 3.1 base score of 8.8 reflects the critical impact on confidentiality, integrity, and availability, as successful exploitation could allow an attacker to gain elevated access rights, potentially leading to unauthorized data access, modification, or service disruption. The scope of the vulnerability is unchanged (S:U), meaning the impact is confined to the vulnerable component. No known exploits in the wild have been reported, but the ease of exploitation combined with the high impact makes this a significant threat for organizations using this software.

For European organizations using Central Dogma 0.51.1, this vulnerability poses a serious risk. Privilege escalation can lead to unauthorized access to sensitive configuration data and project authorization files, potentially compromising the integrity and confidentiality of critical business systems. This can result in data breaches, unauthorized changes to system configurations, and disruption of services dependent on Central Dogma. Given that Central Dogma is used for configuration management and version control, exploitation could undermine trust in system configurations and lead to cascading failures or security incidents. Organizations in sectors with strict regulatory requirements around data protection, such as finance, healthcare, and critical infrastructure, could face compliance violations and reputational damage if this vulnerability is exploited.

To mitigate this vulnerability, affected organizations should immediately upgrade Central Dogma to a patched version if available, or apply any vendor-provided patches or workarounds. If patches are not available, organizations should restrict access to the mirroring functionality and the internal Dogma repository to trusted administrators only. Implement strict access controls and audit logging around repository access and authorization file modifications. Network segmentation should be employed to limit exposure of Central Dogma servers to untrusted networks. Additionally, monitoring for unusual privilege escalation attempts and anomalous repository mirroring activities can help detect exploitation attempts early. Regularly reviewing and updating project authorization files and repository permissions can further reduce risk. Finally, organizations should engage with LINE Corporation for updates and security advisories related to this vulnerability.
