Authenticated privilege escalation via hard-coded token key
Published Nov 3, 2022 · Updated Aug 3, 2024
Privilege escalation in Cisco Secure Email, Secure Web Appliance, and Secure Email and Web Manager allows remote authenticated users to impersonate users. The next-generation management interface encrypts API tokens with a hard-coded value, enabling a crafted HTTP request to substitute another valid user identity. Valid credentials and management-interface access are required; successful exploitation executes commands with the impersonated account's privileges.
