A vulnerability in the default configuration of the Simple Network Management Protocol (SNMP) feature of Cisco Wide Area Application Services (WAAS) Software could allow an unauthenticated, remote attacker to read data from an affected device via SNMP. The vulnerability is due to a hard-coded, read-only community string in the configuration file for the SNMP daemon. An attacker could exploit this vulnerability by using the static community string in SNMP version 2c queries to an affected device. A successful exploit could allow the attacker to read any data that is accessible via SNMP on the affected device. Note: The static credentials are defined in an internal configuration file and are not visible in the current operation configuration ('running-config') or the startup configuration ('startup-config'). Cisco Bug IDs: CSCvi40137.

A vulnerability in the Tool for Auto-Registered Phones Support (TAPS) of Cisco Unified Communications Manager (UCM) and Cisco Unified Communications Manager Session Management Edition (SME) could allow an unauthenticated, remote attacker to conduct directory traversal attacks on an affected device.

An attacker could exploit this vulnerability by sending a crafted request to the TAPS interface. A successful exploit could allow the attacker to read arbitrary files in the system.

A vulnerability in the API of Cisco IoT Field Network Director (FND) could allow an unauthenticated, remote attacker to view sensitive information on an affected system. The vulnerability exists because the affected software does not properly authenticate API calls. An attacker could exploit this vulnerability by sending API requests to an affected system. A successful exploit could allow the attacker to view sensitive information on the affected system, including information about the devices that the system manages, without authentication.

A vulnerability in the API subsystem of Cisco Meetings App could allow an unauthenticated, remote attacker to retain and reuse the Traversal Using Relay NAT (TURN) server credentials that are configured in an affected system. The vulnerability is due to insufficient protection mechanisms for the TURN server credentials. An attacker could exploit this vulnerability by intercepting the legitimate traffic that is generated by an affected system. An exploit could allow the attacker to obtain the TURN server credentials, which the attacker could use to place audio/video calls and forward packets through the configured TURN server. The attacker would not be able to take control of the TURN server unless the same credentials were used in multiple systems.
