A vulnerability in Cisco Webex Meetings Desktop App could allow an unauthenticated, remote attacker to execute programs on an affected end-user system. The vulnerability is due to improper validation of input that is supplied to application URLs. The attacker could exploit this vulnerability by persuading a user to follow a malicious URL. A successful exploit could allow the attacker to cause the application to execute other programs that are already present on the end-user system. If malicious files are planted on the system or on an accessible network file path, the attacker could execute arbitrary code on the affected system.Show less

A vulnerability in the Enhanced Charging Service (ECS) functionality of Cisco ASR 5000 Series Aggregation Services Routers could allow an unauthenticated, remote attacker to bypass the traffic classification rules on an affected device. The vulnerability is due to insufficient input validation of user traffic going through an affected device. An attacker could exploit this vulnerability by sending a malformed HTTP request to an affected device. A successful exploit could allow the attacker to bypass the traffic classification rules and potentially avoid being charged for traffic consumption.Show less
