Cisco Tivoli Business Service Manager (TBSM), which is part of Cisco Hosted Collaboration Mediation (HCM), contains a vulnerability that could allow an unauthenticated, remote attacker to cause a partial denial of service (DoS). An attacker could exploit this vulnerability by sending a flood of TCP packets directed to ports 17310-17542 on Cisco TBSM. A successful attack could cause certain services to hang while the attack lasts. Cisco has confirmed the vulnerability in a security notice; however, software updates are not available. To exploit the vulnerability, an attacker would need access to trusted, internal networks to send a series of TCP packets to the targeted system. This access requirement may reduce the likelihood of a successful attack. Customers are advised to review the bug report in the vendor announcements section for a current list of affected versions.
The Cisco Product Security Incident Response Team (PSIRT) is not aware of any public announcements or malicious use of the vulnerability that is described in this advisory.
