CVE ID : CVE-2026-26335

Published : Feb. 13, 2026, 9:16 p.m. | 1 hour, 13 minutes ago

Description : 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.
