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. The lack of available disk space could lead to a DoS condition in which the application functions could operate abnormally, making the appliance unstable. This vulnerability affects the following Cisco Voice Operating System (VOS)-based products: Emergency Responder, Finesse, Hosted Collaboration Mediation Fulfillment, MediaSense, Prime License Manager, SocialMiner, Unified Communications Manager (UCM), Unified Communications Manager IM and Presence Service (IM&P - earlier releases were known as Cisco Unified Presence), Unified Communication Manager Session Management Edition (SME), Unified Contact Center Express (UCCx), Unified Intelligence Center (UIC), Unity Connection, Virtualized Voice Browser. This vulnerability also affects Prime Collaboration Assurance and Prime Collaboration Provisioning. Cisco Bug IDs: CSCvd10872, CSCvf64322, CSCvf64332, CSCvi29538, CSCvi29543, CSCvi29544, CSCvi29546, CSCvi29556, CSCvi29571, CSCvi31738, CSCvi31741, CSCvi31762, CSCvi31807, CSCvi31818, CSCvi31823.

According to its self-reported version, the Cisco Finesse Software is affected by a denial of service vulnerability. The vulnerability occurs because a certain system log file does not have a maximum size restriction. This could allow an unauthenticated, remote attacker to cause high disk utilization, resulting in a denial of service (DoS) condition.

According to its self-reported version, the Cisco Emergency Responder (CER) is affected by a denial of service vulnerability. The vulnerability occurs because a certain system log file does not have a maximum size restriction. This could allow an unauthenticated, remote attacker to cause high disk utilization, resulting in a denial of service (DoS) condition.

A vulnerability in local file management for Cisco Unity Connection could allow an unauthenticated, remote attacker to cause high disk utilization, resulting in a denial of service (DoS) condition.
