CVE-2007-2344 in NetSight Inventory Manager
Summary
by MITRE
The BOOTPD component in Enterasys NetSight Console 2.1 and NetSight Inventory Manager 2.1, and possibly earlier, on Windows allows remote attackers to cause a denial of service (daemon crash) via a UDP packet that contains an invalid "packet type" field.

The vulnerability identified as CVE-2007-2344 affects the BOOTPD component within Enterasys NetSight Console 2.1 and NetSight Inventory Manager 2.1 running on Windows platforms. This issue represents a classic denial of service vulnerability that exploits improper input validation mechanisms within the BOOTP daemon implementation. The vulnerability specifically targets the handling of UDP packets where the packet type field contains invalid data, leading to daemon instability and potential system crash conditions that disrupt normal network operations.
The technical flaw resides in the insufficient validation of the packet type field within the BOOTP protocol implementation. When the BOOTPD service receives a UDP packet with an invalid packet type value, the daemon fails to properly handle this malformed input and subsequently crashes. This represents a fundamental lack of input sanitization and error handling that aligns with CWE-20, which describes "Improper Input Validation" as a core weakness in software design. The vulnerability demonstrates poor defensive programming practices where the system does not anticipate or properly manage unexpected input conditions that could be deliberately crafted by malicious actors.
From an operational perspective, this vulnerability presents significant risk to network infrastructure management systems that rely on Enterasys NetSight products for network monitoring and inventory management. The remote attack vector means that unauthorized users can potentially disrupt critical network operations without requiring local access or authentication credentials. This denial of service condition directly impacts availability of network management services and can lead to extended downtime for network administrators who depend on these tools for maintaining network health and configuration management. The impact extends beyond simple service disruption as it can interfere with network boot processes and DHCP functionality that may rely on similar BOOTP mechanisms.
The vulnerability can be addressed through several mitigation strategies that align with established cybersecurity frameworks. Immediate patching of affected Enterasys NetSight products represents the most effective remediation approach, as this would resolve the underlying input validation issues within the BOOTPD component. Network segmentation and access control measures can provide additional defense in depth by limiting unauthorized access to the affected systems. Implementing network monitoring solutions that can detect and alert on malformed UDP traffic patterns helps in early identification of potential exploitation attempts. From an ATT&CK framework perspective, this vulnerability maps to T1499.004 which covers "Endpoint Denial of Service" and T1595.001 for "Network Denial of Service" techniques. Organizations should also consider implementing intrusion detection systems that can identify anomalous BOOTP packet patterns and establish proper network access controls to limit exposure of vulnerable services to untrusted networks.
