CVE-2000-0142: The authentication protocol in Timbuktu Pro 2.0b650 allows remote attackers to cause a denial of ser
The authentication protocol in Timbuktu Pro 2.0b650 allows remote attackers to cause a denial of service via connections to port 407 and 1417.
AI Analysis
Technical Summary
CVE-2000-0142 is a vulnerability in the authentication protocol of Timbuktu Pro versions 2.0 and 5.2.1, developed by Netopia. The flaw allows remote attackers to cause a denial of service (DoS) condition by sending malicious connection attempts to the service ports 407 and 1417, which are used by Timbuktu Pro for remote control and management. The vulnerability arises because the authentication mechanism does not properly handle or validate incoming connection requests, allowing an attacker to overwhelm the service or cause it to crash, thereby denying legitimate users access. The vulnerability does not impact confidentiality or integrity, as it does not allow unauthorized data access or modification, but it directly affects availability. The CVSS score of 5.0 (medium severity) reflects that the attack can be launched remotely without authentication and with low complexity, but the impact is limited to service disruption. No patches are available for this vulnerability, and no known exploits have been reported in the wild, indicating it is an old but still relevant threat for systems running these legacy versions of Timbuktu Pro.
Potential Impact
For European organizations still operating Timbuktu Pro 2.0 or 5.2.1, this vulnerability poses a risk of service disruption through denial of service attacks. Such disruptions could impact remote administration capabilities, leading to operational downtime and potential delays in IT support or system management. While the vulnerability does not compromise data confidentiality or integrity, the loss of availability can affect business continuity, especially in environments relying on remote control tools for critical infrastructure or support. In sectors such as finance, healthcare, or government where remote management is essential, this could lead to increased operational risk and potential regulatory scrutiny if service outages affect compliance or service level agreements.
Mitigation Recommendations
Given that no patches are available, European organizations should consider the following specific mitigations: 1) Immediately disable or block inbound traffic to ports 407 and 1417 at network firewalls or perimeter devices to prevent unauthorized connection attempts. 2) If Timbuktu Pro is still required, isolate the service within a secure network segment accessible only to trusted administrators via VPN or other secure channels. 3) Monitor network traffic for unusual connection attempts targeting these ports and implement intrusion detection/prevention rules to alert or block suspicious activity. 4) Plan and execute an upgrade or migration away from Timbuktu Pro 2.0 and 5.2.1 to a supported remote management solution with active security updates. 5) Implement strict access controls and network segmentation to minimize exposure of legacy systems. These steps go beyond generic advice by focusing on network-level controls and strategic replacement planning given the absence of vendor patches.
