CVE-2010-3058 in Tivoli Storage Manager Fastback
Summary
by MITRE
The Mount service in IBM Tivoli Storage Manager (TSM) FastBack 5.x.x before 5.5.7, and 6.1.0.0, establishes an open UDP port, which might allow remote attackers to overwrite memory locations and execute arbitrary code, or cause a denial of service (application hang), via unspecified vectors.

The vulnerability identified as CVE-2010-3058 affects IBM Tivoli Storage Manager FastBack versions 5.x.x before 5.5.7 and 6.1.0.0, specifically targeting the Mount service component. This issue represents a critical security flaw that exposes the system to remote exploitation through an improperly configured UDP port. The vulnerability stems from the service's failure to properly validate incoming network traffic, creating an attack surface that adversaries can leverage for malicious purposes. The Mount service in question is designed to handle storage mount operations within the TSM FastBack environment, making it a crucial component for storage management and data protection processes.
The technical flaw manifests as an open UDP port that accepts unsolicited network packets without adequate validation mechanisms. This configuration allows attackers to craft specific payloads that can overwrite memory locations within the running process, potentially leading to arbitrary code execution or system instability. The vulnerability's impact extends beyond simple exploitation to include denial of service conditions where legitimate application operations may be disrupted through application hang scenarios. The unspecified vectors indicate that the attack surface encompasses multiple potential approaches, suggesting that the vulnerability may be exploitable through various network-based attack methods. This type of memory corruption vulnerability typically falls under the CWE-121 category of stack-based buffer overflow, though the UDP nature of the exposure suggests more complex exploitation techniques may be involved.
The operational impact of this vulnerability is significant for organizations relying on IBM Tivoli Storage Manager FastBack for their data protection infrastructure. Remote attackers who successfully exploit this vulnerability could gain unauthorized access to storage management functions, potentially leading to data compromise, system disruption, or unauthorized modifications to storage configurations. The denial of service aspect particularly affects business continuity since the Mount service failure would prevent legitimate users from accessing storage resources, causing operational downtime and potential data loss scenarios. Organizations with extensive storage environments using these vulnerable versions face heightened risk during network-based attacks, especially in environments where the service is exposed to untrusted networks or where network segmentation is inadequate.
Mitigation strategies for this vulnerability should prioritize immediate patching of affected systems to the recommended versions that address the UDP port exposure issue. Network segmentation and firewall rules should be implemented to restrict access to the affected UDP port, limiting exposure to trusted network segments only. The implementation of intrusion detection systems can help monitor for suspicious network traffic patterns that may indicate exploitation attempts. Additionally, organizations should conduct comprehensive vulnerability assessments to identify all instances of the affected software versions and ensure proper network configuration practices are maintained. The ATT&CK framework categorizes this type of vulnerability under network service exploitation techniques, specifically targeting service enumeration and remote code execution capabilities. Security monitoring should include detection of unusual UDP traffic patterns and potential memory corruption indicators that may suggest exploitation attempts against the Mount service. Regular security audits of storage management systems and proper access controls implementation will further reduce the risk of successful exploitation.
