Cisco TelePresence Management Suite contains a vulnerability that could allow an unauthenticated, remote attacker to cause a denial of service condition. Updates are available.
A vulnerability in the 64-bit SNMP server of Cisco TelePresence Management Suite (TMS) could allow an unauthenticated, remote attacker to terminate the TMSSNMPService.exe process.
The vulnerability is due to improper input validation. An attacker could exploit this vulnerability by sending SNMP traps to a 64-bit TMS server. An exploit could allow the attacker to cause a partial denial of service condition.
Cisco has confirmed the vulnerability in a security notice and software updates are available.
At the time this alert was first published, Cisco TMS versions 14.2 and prior were vulnerable. Later versions of Cisco TMS may also be affected.
To exploit the vulnerability, an attacker would likely need access to trusted, internal networks to send crafted SNMP traps to the targeted system. This access requirement may reduce the likelihood of a successful attack.
Customers are advised to review the bug reports in the Vendor Announcements section for a current list of affected versions.
Cisco indicates through the CVSS score that functional exploit code exists; however, the code is not known to be publicly available.
An unauthenticated, remote attacker could exploit this vulnerability to cause the TMSSNMPService.exe process running on an affected device to terminate unexpectedly, resulting in a denial of service (DoS) condition.
The vulnerability is due to improper validation of user-supplied input processed by the affected software.
An unauthenticated, remote attacker could exploit this vulnerability by sending crafted SNMP traps to an affected device. Processing the crafted SNMP traps could cause the TMSSNMPService.exe process running on the targeted device to crash, resulting in a DoS condition.
Administrators are advised to apply the appropriate updates.
Administrators are advised to allow only trusted users to have network access.
Administrators may consider using IP-based access control lists (ACLs) to allow only trusted systems to access the affected systems.
Administrators are advised to monitor affected systems.
