Security Vulnerabilities - CVEs Published In April 2018
A vulnerability in the device manager web interface of Cisco Industrial Ethernet Switches could allow an unauthenticated, remote attacker to conduct a cross-site request forgery (CSRF) attack against a user of an affected system. The vulnerability is due to insufficient CSRF protection by the device manager web interface. An attacker could exploit this vulnerability by persuading a user of the interface to follow a malicious link or visit an attacker-controlled website. A successful exploit could allow the attacker to submit arbitrary requests to an affected device via the device manager web interface with the privileges of the user. This vulnerability affects the following Cisco Industrial Ethernet (IE) Switches if they are running a vulnerable release of Cisco IOS Software: IE 2000 Series, IE 2000U Series, IE 3000 Series, IE 3010 Series, IE 4000 Series, IE 4010 Series, IE 5000 Series. Cisco Bug IDs: CSCvc96405.

A vulnerability in the peer-to-peer message processing functionality of Cisco Packet Data Network Gateway could allow an unauthenticated, remote attacker to cause the Session Manager (SESSMGR) process on an affected device to restart, resulting in a denial of service (DoS) condition. The vulnerability is due to incorrect validation of peer-to-peer packet headers. An attacker could exploit this vulnerability by sending a crafted peer-to-peer packet through an affected device. A successful exploit could allow the attacker to cause the SESSMGR process on the affected device to restart unexpectedly, which could briefly impact traffic while the SESSMGR process restarts and result in a DoS condition. Cisco Bug IDs: CSCvg88786.

A vulnerability in Cisco IOS XE Software running on Cisco cBR Series Converged Broadband Routers could allow an unauthenticated, adjacent attacker to cause high CPU usage on an affected device, resulting in a denial of service (DoS) condition. The vulnerability is due to the incorrect handling of certain DHCP packets. An attacker could exploit this vulnerability by sending certain DHCP packets to a specific segment of an affected device. A successful exploit could allow the attacker to increase CPU usage on the affected device and cause a DoS condition. Cisco Bug IDs: CSCvg73687.

A vulnerability in the web-based management interface of Cisco MATE Collector could allow an unauthenticated, remote attacker to conduct a cross-site request forgery (CSRF) attack and perform arbitrary actions on an affected device. The vulnerability is due to insufficient CSRF protections for the web-based management interface of an affected device. An attacker could exploit this vulnerability by persuading a user of the interface to follow a malicious link. A successful exploit could allow the attacker to perform arbitrary actions on a targeted device via a web browser and with the privileges of the user. Cisco Bug IDs: CSCvh31222.

A vulnerability in the web interface of Cisco MATE Live could allow an unauthenticated, remote attacker to view and download the contents of certain web application virtual directories. The vulnerability is due to lack of proper input validation and authorization of HTTP requests. An attacker could exploit this vulnerability by sending a malicious HTTP request to the targeted application. An exploit could allow the attacker to view sensitive information that should require authentication. Cisco Bug IDs: CSCvh31272.

A vulnerability in the web framework of Cisco Unified Communications Manager could allow an authenticated, local attacker to view sensitive data that should be restricted. This could include LDAP credentials. The vulnerability is due to insufficient protection of database tables over the web interface. An attacker could exploit this vulnerability by browsing to a specific URL. An exploit could allow the attacker to view sensitive information that should have been restricted. Cisco Bug IDs: CSCvf22116.

A vulnerability in the web framework of the Cisco Digital Network Architecture Center (DNA Center) could allow an unauthenticated, remote attacker to communicate with the Kong API server without restriction. The vulnerability is due to an overly permissive Cross Origin Resource Sharing (CORS) policy. An attacker could exploit this vulnerability by convincing a user to follow a malicious link. An exploit could allow the attacker to communicate with the API and exfiltrate sensitive information. Cisco Bug IDs: CSCvh99208.

A vulnerability in the Secure Sockets Layer (SSL) Engine of Cisco Firepower System Software could allow an unauthenticated, remote attacker to cause a denial of service (DoS) condition. The vulnerability is due to improper error handling while processing SSL traffic. An attacker could exploit this vulnerability by sending a large volume of crafted SSL traffic to the vulnerable device. A successful exploit could allow the attacker to degrade the device performance by triggering a persistent high CPU utilization condition. Cisco Bug IDs: CSCvh89340.

A vulnerability in the IPsec Manager of Cisco StarOS for Cisco Aggregation Services Router (ASR) 5000 Series Routers and Virtualized Packet Core (VPC) System Software could allow an unauthenticated, remote attacker to terminate all active IPsec VPN tunnels and prevent new tunnels from being established, resulting in a denial of service (DoS) condition. The vulnerability is due to improper processing of corrupted Internet Key Exchange Version 2 (IKEv2) messages. An attacker could exploit this vulnerability by sending crafted IKEv2 messages toward an affected router. A successful exploit could allow the attacker to cause the ipsecmgr service to reload. A reload of this service could cause all IPsec VPN tunnels to be terminated and prevent new tunnels from being established until the service has restarted, resulting in a DoS condition. This vulnerability affects the following Cisco products when they are running Cisco StarOS: Cisco Aggregation Services Router (ASR) 5000 Series Routers, Virtualized Packet Core (VPC) System Software. Cisco Bug IDs: CSCve29605.
