The issue is due to insufficient input validation when extracting uploaded software packages, allowing an authenticated, remote attacker with Administrator privileges to execute arbitrary commands using root-level privileges. An attacker could exploit this by authenticating to an affected device and uploading a crafted software package, potentially executing commands on the underlying operating system with root-level privileges.

A successful exploit could allow the attacker to execute commands on the underlying operating system with root-level privileges.

The issue is related to the Connectivity Fault Management (CFM) feature of Cisco IOS XR Software. It is caused by incorrect processing of invalid continuity check messages (CCMs), which could allow an unauthenticated, remote attacker to cause a denial of service (DoS) condition on an affected device. An attacker could exploit this by sending crafted CCMs to an affected device, potentially causing the CFM service to crash when a user displays information about maintenance end points (MEPs) for peer MEPs.

A vulnerability in the SSL/TLS implementation of Cisco Nexus Dashboard could allow an unauthenticated, remote attacker to alter communications with associated controllers or view sensitive information. This issue exists because SSL server certificates are not validated when Cisco Nexus Dashboard is establishing a connection to controllers. An attacker could exploit this vulnerability by using man-in-the-middle techniques to intercept traffic and then using a crafted certificate to impersonate the controllers. A successful exploit could allow the attacker to alter communications between devices or view sensitive information, including Administrator credentials for these controllers.
