A vulnerability in the web management interface of Cisco Unity Connection could allow an authenticated remote attacker to overwrite files on the underlying filesystem. The vulnerability is due to insufficient input validation. An attacker could exploit this vulnerability by sending a crafted HTTP request to the web management interface. A successful exploit could allow the attacker to overwrite files on the underlying filesystem of an affected system. Valid administrator credentials are required to access the system.

A vulnerability in the web-based interface of Cisco Unified Communications Manager, Cisco Unified Communications Manager Session Management Edition (SME), Cisco Unified Communications Manager IM and Presence (Unified CM IM&P) Service, and Cisco Unity Connection could allow an unauthenticated, remote attacker to conduct a cross-site request forgery (CSRF) attack on an affected system. The vulnerability is due to insufficient CSRF protections by the affected software. An attacker could exploit this vulnerability by persuading a targeted user to click a malicious link. A successful exploit could allow the attacker to send arbitrary requests that could change the password of a targeted user. An attacker could then take unauthorized actions on behalf of the targeted user.

A vulnerability in the web-based interface of multiple Cisco Unified Communications products could allow an unauthenticated, remote attacker to conduct a cross-site scripting (XSS) attack against a user of the web-based interface of the affected software. The vulnerability is due to insufficient validation of user-supplied input by the web-based interface of the affected software. An attacker could exploit this vulnerability by persuading a user of the interface to click a crafted link. A successful exploit could allow the attacker to execute arbitrary script code in the context of the affected interface or access sensitive browser-based information.
