Full vulnerability record from the local CVENow database.
Description
A vulnerability in the web UI of Cisco Unified CCX could allow an authenticated, remote attacker to upload and execute arbitrary files. This vulnerability is due to an insufficient input validation associated to file upload mechanisms. An attacker could exploit this vulnerability by uploading a malicious file to the web UI and executing it. A successful exploit could allow the attacker to execute arbitrary commands on the underlying system and elevate privileges to root. To exploit this vulnerability, the attacker must have valid administrative credentials.
