CVE-2023-20102Network attack vector

Authenticated administrator-level code execution via unsafe deserialization

Published Apr 5, 2023 · Updated Oct 28, 2024

Deserialization in Cisco Secure Network Analytics 7.4.1 and earlier allows remote authenticated users to execute code as administrator. The web management interface insufficiently sanitizes user-provided data before parsing it into system memory from a crafted HTTP request. Valid interface credentials are required, and successful exploitation runs arbitrary operating-system code with administrator privileges.
