CVE-2007-2267 in Cluster
Summary
by MITRE
Unspecified vulnerability in Sun Cluster 3.1 and Solaris Cluster 3.2 before 20070424 allows remote authenticated users, operating from a different cluster node, to cause a denial of service (data corruption or send_mondo panic) via unspecified vectors, as demonstrated by EMC Symcli backup software 6.2.1.

The vulnerability identified as CVE-2007-2267 represents a critical security flaw within Sun Cluster 3.1 and Solaris Cluster 3.2 systems prior to the 20070424 patch release. This issue affects high-availability cluster environments where multiple nodes operate in coordinated fashion to ensure system resilience and continuous operation. The vulnerability specifically targets the cluster communication mechanisms that enable nodes to maintain consistent state information and coordinate operations across the distributed system architecture.
The technical flaw manifests as an unspecified weakness in the cluster's handling of authenticated remote connections from different cluster nodes. This vulnerability allows an attacker who has gained authentication credentials on a separate cluster node to exploit the system through unspecified vectors that ultimately result in either data corruption or a send_mondo panic condition. The send_mondo panic represents a specific kernel-level panic condition that occurs when the system encounters an unrecoverable error during cluster communication, leading to system instability and potential complete service disruption.
From an operational perspective, the impact of this vulnerability extends beyond simple denial of service to potentially compromising the integrity of cluster data and the overall stability of the high-availability environment. The demonstration of this vulnerability through EMC Symcli backup software 6.2.1 indicates that legitimate backup operations can be exploited to trigger the malicious behavior, creating a scenario where authorized administrative tasks become potential attack vectors. This particular exploitation method suggests that the vulnerability exists in the cluster's handling of backup-related communications and data transfer protocols that are essential for disaster recovery operations.
The security implications of CVE-2007-2267 align with CWE-119 which addresses weaknesses in memory handling and improper access to resources, particularly in distributed systems where inter-node communication is critical. The vulnerability also maps to ATT&CK technique T1499 which covers network disruption and denial of service attacks, though in this case the attack vector involves legitimate cluster nodes rather than external network intrusions. The fact that this vulnerability can be exploited from a different cluster node rather than from external network access makes it particularly dangerous in environments where network segmentation is not properly implemented or where node compromise has occurred.
Organizations utilizing Sun Cluster or Solaris Cluster systems should immediately implement the patch released on 20070424 to address this vulnerability. Additionally, network segmentation strategies should be reviewed to ensure that cluster nodes are properly isolated and that authentication controls are robust enough to prevent unauthorized access to cluster communication channels. Monitoring for unusual cluster communication patterns or backup operation anomalies should be implemented as part of ongoing security operations to detect potential exploitation attempts. The vulnerability demonstrates the importance of maintaining up-to-date cluster software and the necessity of comprehensive security testing that includes validation of backup and recovery procedures within clustered environments.
