CVE-2025-58445 in atlantis
Summary
by MITRE • 09/06/2025
Atlantis is a self-hosted golang application that listens for Terraform pull request events via webhooks. All versions of Atlantis publicly expose detailed version information through its /status endpoint. This information disclosure could allow attackers to identify and target known vulnerabilities associated with the specific versions, potentially compromising the service's security posture. This issue does not currently have a fix.

The vulnerability identified as CVE-2025-58445 affects Atlantis, a self-hosted golang application designed to handle Terraform pull request events through webhook integration. This application serves as a critical infrastructure component in DevOps environments where automated infrastructure provisioning and management occur. The flaw manifests through the application's /status endpoint which inadvertently exposes comprehensive version information to any unauthorized user who can access the service. This information disclosure represents a significant security risk as it provides attackers with precise details about the application's version, build numbers, and potentially other identifying metadata that could be leveraged for targeted attacks.
The technical nature of this vulnerability aligns with CWE-200, which addresses information exposure through improper information disclosure. The flaw occurs at the application layer where the /status endpoint does not properly sanitize or restrict access to version information that could be used for reconnaissance purposes. This type of information disclosure creates an attack surface that allows threat actors to enumerate the specific Atlantis version running in production environments, enabling them to cross-reference known vulnerabilities and exploits associated with those particular versions. The vulnerability represents a failure in proper access control and information hiding principles, where sensitive metadata is exposed without proper authorization checks.
From an operational impact perspective, this vulnerability creates a direct pathway for attackers to conduct targeted reconnaissance against Atlantis deployments. Once the specific version information is obtained, adversaries can leverage this knowledge to identify potential exploits, patches, or known weaknesses associated with that particular version. The lack of a current fix means that organizations running affected versions of Atlantis remain exposed to potential exploitation attempts. This vulnerability particularly impacts environments where Atlantis is publicly accessible or where network segmentation is inadequate, as it provides attackers with the foundational information needed to plan more sophisticated attacks against the system.
The security implications extend beyond simple information disclosure, as this vulnerability can facilitate subsequent attacks through the ATT&CK framework's reconnaissance phase. Attackers can use the disclosed version information to map out potential attack vectors, identify misconfigurations, or plan social engineering campaigns. Organizations should consider implementing network segmentation to limit access to the /status endpoint and other informational endpoints, while also establishing monitoring for unauthorized access attempts to these endpoints. The absence of a fix at the time of reporting creates an urgent need for defensive measures such as access controls, network monitoring, and regular vulnerability assessments to identify and mitigate potential exploitation attempts.
