See all- CVE-2025-20353Medium
A vulnerability in the web-based management interface of Cisco Catalyst Center could allow an unauthenticated, remote attacker to conduct a cross-site scripting (XSS) attack against a user of the interface. This is due to insufficient validation of user input. An attacker could exploit this by persuading a user to click a crafted link, potentially allowing execution of arbitrary script code or access to sensitive browser-based information.
- CVE-2025-20349Medium
A vulnerability in the REST API of Cisco Catalyst Center could allow an authenticated, remote attacker to execute arbitrary commands in a restricted container as the root user. This is due to insufficient validation of user-supplied input in REST API request parameters. The attacker must have valid credentials for an account with at least the Observer role.
- CVE-2025-20346Medium
A vulnerability in Cisco Catalyst Center could allow an authenticated, remote attacker to execute operations that should require Administrator privileges. The attacker would need valid read-only user credentials. This is due to improper role-based access control (RBAC).
