Description

Palm Pilot HotSync Manager 3.0.4 in Windows 98 allows remote attackers to cause a denial of service, and possibly execute arbitrary commands, via a long string to port 14238 while the manager is in network mode.

Technical Analysis

CVE-1999-1065 is a high-severity vulnerability affecting Palm Pilot HotSync Manager version 3.0.4 running on Windows 98. The HotSync Manager is a synchronization utility that allows Palm Pilot devices to sync data with a PC. In network mode, the HotSync Manager listens on TCP port 14238. This vulnerability arises from improper handling of input data received on this port. Specifically, a remote attacker can send an excessively long string to port 14238, which the HotSync Manager fails to properly validate or sanitize. This can lead to a denial of service (DoS) condition by crashing or hanging the service. Moreover, the vulnerability may allow execution of arbitrary commands, implying that the attacker could potentially gain control over the affected system. The CVSS score of 7.5 reflects the network-based attack vector (AV:N), low attack complexity (AC:L), no authentication required (Au:N), and impacts on confidentiality, integrity, and availability (C:P/I:P/A:P). Since the vulnerability affects an outdated product running on an obsolete operating system (Windows 98), it is unlikely to be encountered in modern environments. No patches are available, and no known exploits have been reported in the wild. However, the vulnerability demonstrates classic buffer overflow or input validation flaws that were common in legacy software, and it highlights the risks of exposing synchronization services over a network without proper security controls.

Potential Impact

For European organizations, the direct impact of this vulnerability today is minimal due to the obsolescence of the affected software and operating system. However, in historical contexts or legacy environments where Palm Pilot HotSync Manager 3.0.4 on Windows 98 might still be in use, exploitation could lead to significant disruption. A successful attack could cause denial of service, interrupting synchronization workflows critical for mobile data management. More severely, arbitrary command execution could allow attackers to compromise the host system, potentially leading to data breaches or lateral movement within a network. Organizations relying on legacy mobile device management or synchronization infrastructure could face operational downtime and data integrity issues. Additionally, if such legacy systems are connected to broader corporate networks, they could serve as entry points for attackers. Given the vulnerability requires no authentication and can be exploited remotely, it poses a risk of unauthorized access and system compromise in environments where it remains deployed.

Mitigation Recommendations

Given that no patches are available for this vulnerability, European organizations should focus on compensating controls and risk mitigation strategies. First, identify and inventory any legacy systems running Palm Pilot HotSync Manager 3.0.4 on Windows 98. Where possible, decommission or isolate these systems from the corporate network, especially from untrusted networks or the internet. Network segmentation should be employed to restrict access to port 14238, using firewalls or access control lists to block inbound traffic to this port unless explicitly required and secured. If synchronization functionality is still needed, consider migrating to modern, supported synchronization solutions that do not expose vulnerable legacy services. Employ intrusion detection or prevention systems (IDS/IPS) to monitor for anomalous traffic targeting port 14238. Additionally, implement strict network monitoring and logging to detect potential exploitation attempts. Educate IT staff about the risks of legacy software and the importance of timely upgrades or replacements. Finally, maintain robust backup and recovery procedures to minimize impact in case of successful exploitation.
