Cisco Unified Computing System Smart Call Home Input Validation Vulnerability

A vulnerability in Cisco Unified Computing System (UCS) Manager could
allow an authenticated, local attacker to trigger a denial of service (DoS) condition.

The
vulnerability is due to improper input validation. An attacker could
exploit this vulnerability by configuring an invalid contact address for
the Smart Call Home functionality. A successful exploit could allow the
attacker to trigger a DoS condition.

Cisco has confirmed the vulnerability in a security notice and released software updates.

To exploit this vulnerability, an attacker would need to authenticate and have local access to the targeted device. These access requirements may limit the likelihood of a successful exploit.

Cisco indicates through the CVSS score that functional exploit code exists; however, the code is not known to be publicly available.
