CVE-2013-4971 in Puppet
Summary
by MITRE
Puppet Enterprise before 3.2.0 does not properly restrict access to node endpoints in the console, which allows remote attackers to obtain sensitive information via unspecified vectors.

The vulnerability identified as CVE-2013-4971 affects Puppet Enterprise versions prior to 3.2.0, specifically targeting the console component's node endpoint access controls. This issue represents a critical authorization flaw that undermines the security posture of Puppet Enterprise deployments. The vulnerability stems from insufficient access restriction mechanisms within the console's node endpoint implementation, creating pathways for unauthorized information disclosure.
The technical flaw manifests as a lack of proper authentication and authorization checks when accessing node endpoints through the Puppet Enterprise console interface. Attackers can exploit this weakness to gain access to sensitive node information without proper credentials or privileges. The unspecified vectors suggest that multiple attack paths may exist, potentially including direct API calls, web interface manipulation, or indirect exploitation through other compromised components within the Puppet infrastructure. This type of vulnerability falls under the CWE-284 access control weakness category, specifically addressing improper access control in web applications.
The operational impact of this vulnerability is significant for organizations relying on Puppet Enterprise for configuration management and infrastructure automation. Remote attackers who successfully exploit this vulnerability can obtain sensitive information about managed nodes including system configurations, node classifications, certificate information, and potentially other administrative details. This information exposure can lead to further attacks targeting the underlying infrastructure, as attackers gain insights into system configurations and deployment patterns. The vulnerability essentially provides an information disclosure attack vector that can serve as a foundation for more sophisticated exploitation attempts.
Organizations should immediately upgrade to Puppet Enterprise 3.2.0 or later versions to address this vulnerability. Additionally, implementing network segmentation and access controls around the Puppet Enterprise console can provide temporary mitigation while upgrades are being deployed. Security monitoring should be enhanced to detect unusual access patterns to node endpoints, and regular security assessments should be conducted to identify similar access control weaknesses in other components of the Puppet infrastructure. This vulnerability aligns with ATT&CK technique T1087.002 for account discovery and T1068 for exploit for privilege escalation, as unauthorized access to node information can facilitate further compromise of the managed infrastructure.
