Title
Cisco Unity Connection Arbitrary File Download Vulnerability
Summary
Multiple vulnerabilities in Cisco Unity Connection could allow an authenticated, remote attacker to download arbitrary files from an affected system. To exploit these vulnerabilities, the attacker must have valid administrative credentials.  These vulnerabilities are due to improper sanitization of user input to the web-based management interface. An attacker could exploit these vulnerabilities by sending a crafted HTTPS request. A successful exploit could allow the attacker to download arbitrary files from an affected system.
