CVE-2012-2734 in Cumin
Summary
by MITRE
Multiple cross-site request forgery (CSRF) vulnerabilities in Cumin before 0.1.5444, as used in Red Hat Enterprise Messaging, Realtime, and Grid (MRG) 2.0, allow remote attackers to hijack the authentication of arbitrary users for requests that execute commands via unspecified vectors.

The vulnerability identified as CVE-2012-2734 represents a critical cross-site request forgery flaw affecting the Cumin framework version prior to 0.1.5444. This vulnerability specifically impacts Red Hat Enterprise Messaging, Realtime, and Grid (MRG) 2.0 platforms, creating a significant security risk that allows remote attackers to manipulate authenticated sessions. The flaw operates by enabling attackers to craft malicious requests that appear to originate from legitimate authenticated users, thereby bypassing the normal authentication mechanisms that should protect system operations. The vulnerability falls under CWE-352, which specifically addresses Cross-Site Request Forgery vulnerabilities, and aligns with ATT&CK technique T1566.001 for initial access through spearphishing attachments.
The technical implementation of this CSRF vulnerability stems from insufficient validation of request origins and lack of proper anti-CSRF token implementation within the Cumin framework. Attackers can exploit this weakness by tricking authenticated users into visiting malicious web pages or clicking on compromised links that automatically submit requests to the vulnerable MRG systems. These requests can execute arbitrary commands on behalf of the authenticated user, potentially leading to complete system compromise. The unspecified vectors mentioned in the description suggest that the vulnerability manifests across multiple attack surfaces within the framework, making it particularly dangerous as it may affect various system functions and operations.
The operational impact of this vulnerability extends beyond simple data theft or modification, as it enables attackers to execute commands on the target systems with the privileges of authenticated users. This capability can lead to unauthorized access to sensitive messaging systems, data manipulation, system disruption, and potentially lateral movement within network environments where MRG components are deployed. The affected Red Hat MRG 2.0 platforms, which are designed for high-performance messaging and grid computing, become particularly vulnerable since they handle critical enterprise communications and processing tasks. Organizations relying on these platforms for mission-critical operations face significant risk of service disruption and data compromise.
Mitigation strategies for CVE-2012-2734 should prioritize immediate patching of the Cumin framework to version 0.1.5444 or later, which contains the necessary fixes for the CSRF vulnerabilities. System administrators should implement proper input validation and implement anti-CSRF tokens for all state-changing operations within the affected systems. Network segmentation and monitoring solutions should be deployed to detect unusual patterns of authenticated requests that might indicate CSRF attack attempts. Additionally, security awareness training should be conducted to help users recognize potentially malicious links and attachments that could be used to exploit this vulnerability. The remediation process should include thorough testing of patched systems to ensure that the CSRF protections are properly implemented and functioning as intended. Organizations should also consider implementing web application firewalls and additional authentication mechanisms to provide defense-in-depth against similar vulnerabilities.
