A vulnerability in the Bulk Administration Tool (BAT) for Cisco Unity Connection could allow an authenticated, remote attacker to cause high disk utilization, resulting in a denial of service (DoS) condition. The vulnerability exists because the affected software does not restrict the maximum size of certain files that can be written to disk. An attacker who has valid administrator credentials for an affected system could exploit this vulnerability by sending a crafted, remote connection request to an affected system. A successful exploit could allow the attacker to write a file that consumes most of the available disk space on the system, causing application functions to operate abnormally and leading to a DoS condition. Una vulnerabilidad en el BAT (Bulk Administration Tool) en Cisco Unity Connection podría permitir que un atacante remoto autenticado provoque un gran uso del disco, lo que resulta en una condición de denegación de servicio (DoS). • http://www.securitytracker.com/id/1041782 https://tools.cisco.com/security/center/content/CiscoSecurityAdvisory/cisco-sa-20181003-unity-dos • CWE-399: Resource Management Errors CWE-400: Uncontrolled Resource Consumption •

A vulnerability in the web framework of Cisco Unity Connection could allow an unauthenticated, remote attacker to conduct a cross-site scripting (XSS) attack against the user of the web interface of an affected system. The vulnerability is due to insufficient input validation of certain parameters that are passed to the affected software via the HTTP GET and HTTP POST methods. An attacker who can convince a user to follow an attacker-supplied link could execute arbitrary script or HTML code in the user's browser in the context of an affected site. Cisco Bug IDs: CSCvf76417. Una vulnerabilidad en el código framework de red de Cisco Unity Connection podría permitir que un atacante remoto sin autenticar lleve a cabo un ataque de Cross-Site Scripting (XSS) contra un usuario de dicha interfaz en el sistema afectado. • http://www.securityfocus.com/bid/104426 http://www.securitytracker.com/id/1041067 https://tools.cisco.com/security/center/content/CiscoSecurityAdvisory/cisco-sa-20180606-cuc-xss • CWE-79: Improper Neutralization of Input During Web Page Generation ('Cross-site Scripting') •

Multiple Cisco products are affected by a vulnerability in local file management for certain system log files of Cisco collaboration products that could allow an unauthenticated, remote attacker to cause high disk utilization, resulting in a denial of service (DoS) condition. The vulnerability occurs because a certain system log file does not have a maximum size restriction. Therefore, the file is allowed to consume the majority of available disk space on the appliance. An attacker could exploit this vulnerability by sending crafted remote connection requests to the appliance. Successful exploitation could allow the attacker to increase the size of a system log file so that it consumes most of the disk space. • https://tools.cisco.com/security/center/content/CiscoSecurityAdvisory/cisco-sa-20180606-diskdos • CWE-399: Resource Management Errors CWE-400: Uncontrolled Resource Consumption •

A vulnerability in the SMTP relay of Cisco Unity Connection could allow an unauthenticated, remote attacker to send unsolicited email messages, aka a Mail Relay Vulnerability. The vulnerability is due to improper handling of domain information in the affected software. An unauthenticated, remote attacker could exploit this vulnerability by sending crafted requests to the targeted application. A successful exploit could allow the attacker to send email messages to arbitrary addresses.

A vulnerability in the upgrade mechanism of Cisco collaboration products based on the Cisco Voice Operating System software platform could allow an unauthenticated, remote attacker to gain unauthorized, elevated access to an affected device. The vulnerability occurs when a refresh upgrade (RU) or Prime Collaboration Deployment (PCD) migration is performed on an affected device. When a refresh upgrade or PCD migration is completed successfully, an engineering flag remains enabled and could allow root access to the device with a known password. If the vulnerable device is subsequently upgraded using the standard upgrade method to an Engineering Special Release, service update, or a new major release of the affected product, this vulnerability is remediated by that action. Note: Engineering Special Releases that are installed as COP files, as opposed to the standard upgrade method, do not remediate this vulnerability. • http://www.securityfocus.com/bid/101865 http://www.securitytracker.com/id/1039813 http://www.securitytracker.com/id/1039814 http://www.securitytracker.com/id/1039815 http://www.securitytracker.com/id/1039816 http://www.securitytracker.com/id/1039817 http://www.securitytracker.com/id/1039818 http://www.securitytracker.com/id/1039819 http://www.securitytracker.com/id/1039820 https://tools.cisco.com/security/center/content/CiscoSecurityAdvisory/cisco-sa-20171115-vos • CWE-287: Improper Authentication •
