Cisco IoT Field Network Director Improper Access Control Vulnerability

A vulnerability in the access control functionality of Cisco IoT Field Network Director (FND) could allow an authenticated, remote attacker to view lists of users from different domains that are configured on an affected system.

The vulnerability is due to improper access control. An attacker could exploit this vulnerability by sending an API request that alters the domain for a requested user list on an affected system. A successful exploit could allow the attacker to view lists of users from different domains on the affected system.

Cisco has released software updates that address this vulnerability. There are no workarounds that address this vulnerability.

Cisco Expressway Software Unauthorized Access Information Disclosure Vulnerability

A vulnerability in the Traversal Using Relays around NAT (TURN) server component of Cisco Expressway software could allow an unauthenticated, remote attacker to bypass security controls and send network traffic to restricted destinations.

The vulnerability is due to improper validation of specific connection information by the TURN server within the affected software. An attacker could exploit this issue by sending specially crafted network traffic to the affected software. A successful exploit could allow the attacker to send traffic through the affected software to destinations beyond the application, possibly allowing the attacker to gain unauthorized network access.

Cisco has released software updates that address this vulnerability. There are no workarounds that address this vulnerability.

Cisco IoT Field Network Director Unauthenticated REST API Vulnerability

A vulnerability in the REST API of Cisco IoT Field Network Director (FND) could allow an unauthenticated, remote attacker to access the back-end database of an affected system.

The vulnerability exists because the affected software does not properly authenticate REST API calls. An attacker could exploit this vulnerability by obtaining a cross-site request forgery (CSRF) token and then using the token with REST API requests. A successful exploit could allow the attacker to access the back-end database of the affected device and read, alter, or drop information.

Cisco has released software updates that address this vulnerability. There are no workarounds that address this vulnerability.

Cisco Secure Web Appliance Privilege Escalation Vulnerability

A vulnerability in the log subscription subsystem of Cisco AsyncOS for the Cisco Secure Web Appliance (formerly Web Security Appliance) could allow an authenticated, local attacker to perform command injection and elevate privileges to root.

This vulnerability is due to insufficient validation of user-supplied input for the web interface and CLI. An attacker could exploit this vulnerability by authenticating to the affected device and injecting scripting commands in the scope of the log subscription subsystem. A successful exploit could allow the attacker to execute arbitrary commands on the underlying operating system and elevate privileges to root.

Cisco has released software updates that address this vulnerability. There are no workarounds that address this vulnerability.

Cisco Webex Meetings and Cisco Webex Meetings Server Ghost Join Vulnerability

A vulnerability in Cisco Webex Meetings and Cisco Webex Meetings Server could allow an unauthenticated, remote attacker to join a Webex session without appearing on the participant list.

This vulnerability is due to improper handling of authentication tokens by a vulnerable Webex site. An attacker could exploit this vulnerability by sending crafted requests to a vulnerable Cisco Webex Meetings or Cisco Webex Meetings Server site. A successful exploit requires the attacker to have access to join a Webex meeting, including applicable meeting join links and passwords. The attacker could then exploit this vulnerability to join meetings, without appearing in the participant list, while having full access to audio, video, chat, and screen sharing capabilities.

Cisco DNA Spaces Connector Command Injection Vulnerability

A vulnerability in the web-based management interface of Cisco DNA Spaces Connector could allow an unauthenticated, remote attacker to execute arbitrary commands on an affected device.

The vulnerability is due to insufficient validation of user-supplied input in the web-based management interface. An attacker could exploit this vulnerability by sending crafted HTTP requests to the web-based management interface. A successful exploit could allow the attacker to execute arbitrary commands on the underling operating system with privileges of the web-based management application, which is running as a restricted user. This could result in changes being made to pages served by the web-based management application impacting the integrity or availability of the web-based management application.

Cisco has released software updates that address this vulnerability. There are no workarounds that address this vulnerability.
