The vulnerability identified as CVE-2012-2682 affects Cumin, also known as MRG Management Console, which is part of Red Hat Enterprise MRG 2.5. This issue represents a denial of service weakness that can be exploited by attackers who possess specific database privileges. The flaw manifests when a non-ascii character is present in the name of a link within the management console interface, leading to an inaccessible page condition that disrupts normal system operations.
The technical root cause of this vulnerability stems from inadequate input validation within the Cumin application's handling of link names. When the system encounters a non-ascii character in a link name, the application fails to properly process or sanitize this input, resulting in a failure that renders the associated page inaccessible to users. This represents a classic input sanitization issue that falls under CWE-20, which addresses improper input validation in software applications. The vulnerability specifically impacts the web interface component of the management console where link names are processed and displayed.
From an operational perspective, this vulnerability creates significant disruption in enterprise messaging environments that rely on Red Hat Enterprise MRG 2.5 for managing message brokers and related services. Attackers with database privileges can exploit this weakness to render management pages unusable, effectively preventing administrators from accessing critical system configuration and monitoring capabilities. This denial of service condition can severely impact operational efficiency and may require manual intervention to restore normal system functionality. The impact is particularly concerning in mission-critical environments where continuous monitoring and management of message brokers is essential for business operations.
The attack vector for this vulnerability requires that an attacker possess specific database privileges within the MRG environment, making it less likely to be exploited by casual threat actors but still a significant concern for organizations with proper access controls. The ATT&CK framework categorizes this vulnerability under the T1499.004 technique for network denial of service, as it specifically targets the availability of network management interfaces. Organizations should implement proper input validation mechanisms and ensure that database users have appropriate privilege levels to prevent unauthorized access to management interfaces. The vulnerability highlights the importance of robust input sanitization practices and proper access control implementations in enterprise management systems.
