CVE-2006-0993 in TippingPoint IPS
Summary
by MITRE
The web management interface in 3Com TippingPoint SMS Server before 2.2.1.4478 does not restrict access to certain directories, which might allow remote attackers to obtain potentially sensitive information such as configuration settings.

The vulnerability identified as CVE-2006-0993 affects the 3Com TippingPoint SMS Server version 2.2.1.4478 and earlier, representing a critical access control flaw in the web management interface. This issue stems from inadequate directory access restrictions that permit unauthorized remote attackers to traverse the system's file structure and access sensitive directories containing configuration data and system information. The vulnerability exists within the server's web interface implementation, where proper authentication and authorization mechanisms fail to adequately protect sensitive resources from unauthenticated access attempts.
The technical flaw manifests as a lack of proper input validation and access control enforcement within the web application layer of the TippingPoint SMS Server. Attackers can exploit this weakness by directly accessing specific URL paths that correspond to sensitive directories without requiring valid credentials or proper authorization. This misconfiguration allows for directory traversal attacks where malicious actors can navigate through the server's file system structure to retrieve configuration files, user credentials, network settings, and other potentially sensitive information that should remain restricted to authorized administrators only. The vulnerability directly maps to CWE-22, which describes improper limitation of a pathname to a restricted directory, commonly known as path traversal or directory traversal attacks.
From an operational perspective, this vulnerability poses significant risks to organizations deploying 3Com TippingPoint SMS Server solutions, as it enables remote attackers to gain unauthorized access to critical system information that could be leveraged for further exploitation. The exposure of configuration settings provides attackers with insights into the system's architecture, network topology, and potentially sensitive operational details that could facilitate more sophisticated attacks. The remote nature of this vulnerability means that attackers do not require physical access to the network or system to exploit it, making the attack surface significantly broader than local privilege escalation vulnerabilities. This weakness directly aligns with ATT&CK technique T1083, which covers directory and file permissions enumeration, and T1046, network service scanning, as attackers can systematically explore the exposed directories to identify valuable information.
The impact of this vulnerability extends beyond simple information disclosure, as the configuration data obtained through exploitation could reveal network infrastructure details, user account information, and system settings that provide attackers with critical intelligence for planning subsequent attacks. Organizations may face compliance violations and regulatory penalties if sensitive information is exposed, particularly in environments governed by standards such as pci dss, hipaa, or soc 2. The vulnerability also represents a significant weakness in the principle of least privilege, as it allows unauthorized access to resources that should only be accessible to system administrators with proper authentication credentials.
Mitigation strategies for CVE-2006-0993 should focus on implementing proper access controls and authentication mechanisms within the web management interface. Organizations should immediately upgrade to 3Com TippingPoint SMS Server version 2.2.1.4478 or later, which contains the necessary patches to address this vulnerability. Network segmentation and firewall rules should be implemented to restrict access to the web management interface to authorized administrative networks only. Additionally, regular security audits and penetration testing should be conducted to identify similar access control weaknesses in other network management interfaces. The implementation of web application firewalls and proper input validation mechanisms can help prevent directory traversal attempts, while regular monitoring of access logs should be enabled to detect suspicious activities targeting the web management interface. Organizations should also consider implementing multi-factor authentication for administrative access and regularly review and update access control policies to ensure that only authorized personnel have access to sensitive system information.
