CVE-2007-1593 in Veritas Volume Replicator
Summary
by MITRE
The administrative service in Symantec Veritas Volume Replicator (VVR) for Windows 3.1 through 4.3, and VVR for Unix 3.5 through 5.0, in Symantec Storage Foundation products allows remote attackers to cause a denial of service (memory consumption and service crash) via a crafted packet to the service port (8199/tcp) that triggers a request for more memory than available, which causes the service to write to an invalid pointer.

The vulnerability described in CVE-2007-1593 represents a critical memory management flaw within Symantec Veritas Volume Replicator administrative services across multiple platform versions. This issue affects both Windows and Unix implementations of the Storage Foundation products, specifically targeting versions 3.1 through 4.3 for Windows and 3.5 through 5.0 for Unix systems. The administrative service operates on TCP port 8199, making it accessible to remote attackers who can exploit this weakness without requiring local system access or authentication credentials.
The technical exploitation mechanism involves sending a specially crafted packet to the designated service port that triggers an improper memory allocation request. This flaw demonstrates characteristics consistent with CWE-122, heap-based buffer overflow conditions, where the service attempts to allocate memory that exceeds available system resources. When the system cannot fulfill the excessive memory request, the administrative service attempts to write to an invalid memory pointer, leading to unpredictable behavior including application crashes and system instability. This type of vulnerability falls under the broader category of memory corruption issues that can result in denial of service conditions.
The operational impact of this vulnerability extends beyond simple service disruption, as it can cause complete administrative service outages that may affect data replication operations and storage management functions. Organizations relying on Symantec Veritas Volume Replicator for critical data protection and business continuity operations face significant risks when this vulnerability remains unpatched. The remote attack vector means that adversaries can exploit this weakness from anywhere on the network, potentially causing cascading failures in storage infrastructure that could affect multiple systems dependent on the replicator service. This vulnerability directly aligns with ATT&CK technique T1499.004, specifically targeting service availability through resource consumption attacks.
Mitigation strategies should prioritize immediate patching of affected systems with the latest Symantec security updates, as this vulnerability represents a known weakness that has been addressed by the vendor. Network segmentation and firewall rules should be implemented to restrict access to TCP port 8199, limiting exposure to trusted administrative networks only. Additionally, monitoring systems should be configured to detect unusual memory consumption patterns or service restarts that may indicate exploitation attempts. Organizations should also consider implementing intrusion detection systems that can identify malformed packets targeting this specific port and service configuration. The vulnerability demonstrates the importance of proper input validation and memory management practices in network services, emphasizing that even administrative services requiring authentication can be exploited remotely if proper safeguards are not implemented.
