CVE-2012-0059 in Network Satellite
Summary
by MITRE
A flaw was found in Spacewalk-backend. This information disclosure vulnerability occurs when a system registration XML-RPC call fails, causing cleartext user passwords to be included in error messages. Remote administrators can exploit this by reading server logs and emails, leading to the unauthorized disclosure of user passwords.

The vulnerability identified as CVE-2012-0059 represents a critical information disclosure flaw within the Spacewalk-backend system, a Red Hat enterprise management platform designed for system inventory and configuration management. This weakness stems from inadequate error handling mechanisms during system registration processes, specifically when XML-RPC calls fail to complete successfully. The flaw manifests when authentication credentials are inadvertently exposed in error messages generated by the system, creating a significant security risk for organizations relying on Spacewalk for their infrastructure management.
The technical implementation of this vulnerability involves the improper sanitization of error messages within the Spacewalk backend components. When system registration attempts fail, the system generates error responses that contain cleartext passwords in their payload, violating fundamental security principles of least privilege and secure error handling. This occurs because the system does not properly filter or redact sensitive information from error messages before they are logged or transmitted through various communication channels. The vulnerability specifically affects the XML-RPC interface used for system registration, where authentication parameters are processed and subsequently exposed in error contexts without adequate protection mechanisms.
From an operational standpoint, this vulnerability creates a severe risk for remote attackers who can exploit the information disclosure by accessing server logs, email notifications, or other channels where error messages are stored or transmitted. The exposure of cleartext passwords through these error messages provides attackers with immediate access to valid authentication credentials for system administrators and users, potentially enabling lateral movement within the network, privilege escalation, and unauthorized access to critical infrastructure components. The impact extends beyond individual user accounts to potentially compromise entire system management domains, given that Spacewalk typically manages multiple systems and requires elevated privileges for operation.
The vulnerability aligns with CWE-200, which addresses information exposure, and demonstrates characteristics consistent with CWE-532, information exposure through log files, and CWE-210, information exposure through error messages. From an ATT&CK framework perspective, this weakness maps to T1078 legitimate credentials and T1566 credential access, as it enables adversaries to obtain valid authentication tokens through indirect means rather than direct attack vectors. Organizations using Spacewalk systems face significant risk of compromise, particularly in environments where system logs and email notifications are not properly secured or monitored for sensitive information exposure.
Mitigation strategies for CVE-2012-0059 require immediate implementation of proper error handling procedures that sanitize all error messages before logging or transmission. System administrators should ensure that authentication parameters and sensitive data are never included in error messages, regardless of the error context. Regular log reviews should be conducted to identify and remove any existing password exposures, while implementing centralized logging solutions with proper access controls and monitoring capabilities. Additionally, organizations should apply the vendor-provided patches and updates immediately, as the vulnerability affects the core system registration functionality and represents a fundamental security flaw in the error handling architecture. Network segmentation and monitoring solutions should be deployed to detect unusual access patterns that might indicate exploitation attempts, while implementing multi-factor authentication for system administrators to reduce the impact of credential compromise.
