Summary
A vulnerability in Cisco Emergency Responder, Cisco Unified Communications Manager (Unified CM), Cisco Unified Communications Manager Session Management Edition (Unified CM SME), and Cisco Unity Connection could allow an authenticated, remote attacker to elevate privileges to root on an affected device.
This vulnerability exists because the application does not properly restrict the files that are being used for upgrades. An attacker could exploit this vulnerability by providing a crafted upgrade file. A successful exploit could allow the attacker to elevate privileges to root. To exploit this vulnerability, the attacker must have valid platform administrator credentials on an affected device.
