CVE-2002-0397 in Red-M
Summary
by MITRE
red-m 1050 (bluetooth access point) publicizes its name ip address and other information in udp packets to a broadcast address which allows any system on the network to obtain potentially sensitive information about the access point device by monitoring udp port 8887.

The vulnerability identified as CVE-2002-0397 affects the red-m 1050 bluetooth access point device, representing a significant information disclosure weakness that undermines network security through improper configuration and protocol implementation. This device fails to adequately protect sensitive operational information, exposing critical system details through unencrypted udp traffic that is broadcast to all network participants. The vulnerability stems from the device's default configuration that publishes its hostname, ip address, and other identifying information without proper access controls or encryption mechanisms, creating an attack surface that adversaries can readily exploit through simple network monitoring techniques.
The technical flaw manifests through the device's use of udp port 8887 as a broadcast channel for disseminating system information to all devices within the local network segment. This implementation violates fundamental security principles by providing unrestricted access to sensitive device metadata without authentication requirements or data sanitization measures. The red-m 1050 device essentially functions as a passive information collector for any network observer, making it an attractive target for reconnaissance activities and network mapping efforts. This behavior aligns with CWE-200, which addresses information exposure through improper information handling, and represents a classic case of insecure default configurations that leave systems vulnerable to unauthorized information gathering.
The operational impact of this vulnerability extends beyond simple information disclosure, as the exposed device information can serve as a foundation for more sophisticated attacks targeting the bluetooth access point. Network administrators and attackers alike can leverage the published information to identify the specific device model, network configuration, and operational parameters, potentially enabling targeted exploitation attempts. The broadcast nature of the udp packets means that this information disclosure occurs without requiring any special privileges or advanced technical skills, making it particularly dangerous as it can be exploited by anyone with basic network monitoring capabilities. This vulnerability directly impacts the confidentiality and integrity aspects of the security triad, as it allows unauthorized parties to gain insights into the network infrastructure that should remain protected.
Mitigation strategies for CVE-2002-0397 should focus on network segmentation and access control measures that prevent unauthorized monitoring of udp port 8887 traffic. Network administrators should implement firewall rules to restrict access to this specific port and consider disabling the information broadcasting functionality if it is not essential for operations. The implementation of network access control lists and proper udp port filtering can significantly reduce the attack surface while maintaining necessary operational functionality. Additionally, organizations should consider updating or replacing vulnerable devices with versions that properly implement access controls and encryption for information dissemination. This vulnerability demonstrates the importance of following the principle of least privilege and the need for regular security assessments to identify and remediate insecure default configurations that can compromise entire network infrastructures. The issue also aligns with ATT&CK technique T1046, which covers network service scanning, as the exposed information makes it easier for adversaries to identify and target specific network devices.
