Kerentanan Use of Hard-coded Cryptographic Key pada calero verasmart. Skor CVSS 3.1 9.8 (Critical) menurut NVD.

Deskripsi (NVD)

Calero VeraSMART versions prior to 2022 R1 use static ASP.NET/IIS machineKey values configured for the VeraSMART web application and stored in C:\\Program Files (x86)\\Veramark\\VeraSMART\\WebRoot\\web.config. An attacker who obtains these keys can craft a valid ASP.NET ViewState payload that passes integrity validation and is accepted by the application, resulting in server-side deserialization and remote code execution in the context of the IIS application.
