**Name of the Vulnerable Software and Affected Versions** Cisco ThousandEyes Virtual Appliance (affected versions not specified) **Description** Insufficient validation of user-supplied input in the SSL certificate handling allows an authenticated remote attacker with administrative credentials to execute arbitrary commands on the underlying operating system as the root user. This is achieved by uploading a crafted certificate to the device. **Recommendations** At the moment, there is no information about a newer version that contains a fix for this vulnerability.

A vulnerability in the BrowserBot component of Cisco ThousandEyes Enterprise Agent could have allowed an authenticated, remote attacker to execute arbitrary commands on Agents on behalf of the BrowserBot synthetics orchestration process. Cisco has addressed this vulnerability in the Cisco ThousandEyes Enterprise Agent, and no customer action is needed. This vulnerability was due to insufficient input validation of command arguments that are supplied by the user. Prior to this vulnerability being addressed, an attacker could have exploited this vulnerability by authenticating to the ThousandEyes SaaS and submitting crafted input into the affected parameter. A successful exploit could have allowed the attacker to execute arbitrary commands within the BrowserBot container as the node user. To exploit this vulnerability, the attacker must have valid user credentials for the ThousandEyes SaaS and the ability to manage transaction tests.

**Name of the Vulnerable Software and Affected Versions** Versions prior to 25.4.270.0 **Description** A local authenticated attacker can manipulate user profile files to add illegitimate challenge response codes into the local user registry under certain conditions. This allows users with the ability to edit their user profile files to elevate their privileges to administrator. **Recommendations** Update to version 25.4.270.0 or later.
