CVE-2011-2925 in Enterprise Mrg
Summary
by MITRE
Cumin in Red Hat Enterprise Messaging, Realtime, and Grid (MRG) 2.0 records broker authentication credentials in a log file, which allows local users to bypass authentication and perform unauthorized actions on jobs and message queues via a direct connection to the broker.

The vulnerability identified as CVE-2011-2925 represents a critical security flaw in the Cumin messaging system component of Red Hat Enterprise Messaging, Realtime, and Grid version 2.0. This issue stems from the improper handling of authentication credentials within the system's logging mechanisms, creating a significant vector for unauthorized access and privilege escalation. The flaw specifically affects the broker authentication process where sensitive credential information is inadvertently written to log files, making it accessible to local users who might exploit this exposure for malicious purposes.
The technical implementation of this vulnerability involves the logging subsystem's failure to properly sanitize or exclude authentication credentials from log entries. When users connect to the broker service, the authentication process generates credential information that gets recorded in log files without adequate protection measures. This design flaw creates a situation where local users with access to these log files can extract the stored credentials and use them to establish unauthorized connections to the message broker. The vulnerability operates at the application level and demonstrates poor security practices in information flow management and access control enforcement.
The operational impact of CVE-2011-2925 extends beyond simple credential theft, as it enables attackers to perform unauthorized actions on message queues and job management systems. Local users who gain access to the log files containing broker credentials can bypass normal authentication mechanisms and directly connect to the broker service, potentially leading to message interception, queue manipulation, job tampering, and unauthorized data access. This vulnerability undermines the fundamental security model of the messaging system and creates opportunities for data breaches, service disruption, and potential lateral movement within the network infrastructure.
Security professionals should recognize this vulnerability as a manifestation of CWE-532, which addresses information exposure through log files, and CWE-287, which covers improper authentication. The flaw aligns with ATT&CK technique T1566, focusing on credential access through log file exploitation, and T1078, covering valid accounts usage for privilege escalation. Organizations using Red Hat MRG 2.0 should implement immediate mitigations including log file access controls, credential sanitization procedures, and regular security auditing of logging mechanisms to prevent unauthorized access to sensitive information. The vulnerability highlights the importance of secure coding practices and proper information handling in distributed messaging systems, particularly when dealing with authentication and authorization processes.
