CVE-2008-0974 in Double-Take
Summary
by MITRE
Double-Take 5.0.0.2865 and earlier, distributed under the HP StorageWorks Storage Mirroring name and other names, allows remote attackers to cause a denial of service (daemon termination) via (1) a large vector<T> value, which raises a "vector<T> too long" exception; or (2) a certain packet that raises an ospace/time/src\date.cpp exception.

The vulnerability identified as CVE-2008-0974 affects Double-Take 5.0.0.2865 and earlier versions, which are distributed under the HP StorageWorks Storage Mirroring brand and other naming conventions. This software represents a data replication and backup solution designed to provide continuous data protection and disaster recovery capabilities in enterprise environments. The vulnerability exists within the daemon process that manages the core replication functionality, making it a critical component that requires robust security measures to prevent unauthorized disruption of data protection services.
The technical flaw manifests through two distinct attack vectors that exploit memory management and exception handling weaknesses within the software implementation. The first vector involves sending a large vector<T> value that triggers a "vector<T> too long" exception, while the second vector utilizes a specific packet that causes an ospace/time/src\date.cpp exception to occur. Both attack methods leverage improper input validation and lack of bounds checking in the software's parsing routines, allowing malicious actors to craft specially formatted data that exceeds the application's expected parameter limits.
From an operational impact perspective, this vulnerability enables remote attackers to cause a denial of service condition that terminates the daemon process, effectively disrupting the data replication service. This termination directly impacts the availability of the backup and recovery mechanisms, potentially leaving critical business data unprotected during the service outage. The attack can be executed remotely without requiring authentication, making it particularly dangerous in networked environments where the software is accessible from external networks. Organizations relying on this software for continuous data protection may experience significant downtime and potential data loss if the daemon fails and manual intervention is required to restore services.
The vulnerability aligns with CWE-129 and CWE-131 categories from the Common Weakness Enumeration framework, specifically addressing issues related to insufficient input validation and improper handling of large data structures. From the MITRE ATT&CK framework perspective, this vulnerability maps to the T1499.004 technique for "Network Denial of Service" and could potentially be used as part of a broader attack chain targeting system availability. Organizations should implement network segmentation to limit access to the affected software, apply vendor-provided patches immediately, and monitor for suspicious network traffic patterns that might indicate exploitation attempts. The remediation process requires updating to a patched version of the software, which should include proper bounds checking and exception handling mechanisms to prevent the exploitation of these memory management vulnerabilities.
