CVE-2026-26335 (GCVE-0-2026-26335)

Title
Calero VeraSMART < 2022 R1 Static IIS Machine Keys Enable ViewState RCE
Summary
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.

Title
Calero VeraSMART < 2022 R1 .NET Remoting Arbitrary File Read Leading to ViewState RCE
Summary
Calero VeraSMART versions prior to 2022 R1 expose an unauthenticated .NET Remoting HTTP service on TCP port 8001. The service publishes default ObjectURIs (including EndeavorServer.rem and RemoteFileReceiver.rem) and permits the use of SOAP and binary formatters with TypeFilterLevel set to Full. An unauthenticated remote attacker can invoke the exposed remoting endpoints to perform arbitrary file read and write operations via the WebClient class. This allows retrieval of sensitive files such as WebRoot\\web.config, which may disclose IIS machineKey validation and decryption keys. An attacker can use these keys to generate a malicious ASP.NET ViewState payload and achieve remote code execution within the IIS application context. Additionally, supplying a UNC path can trigger outbound SMB authentication from the service account, potentially exposing NTLMv2 hashes for relay or offline cracking.

Title
Calero VeraSMART < 2026 R1 Hardcoded Static AES Keys Allow Decryption of Service Credentials
Summary
Calero VeraSMART versions prior to 2026 R1 contain hardcoded static AES encryption keys within Veramark.Framework.dll (Veramark.Core.Config class). These keys are used to encrypt the password of the service account stored in C:\\VeraSMART Data\\app.settings. An attacker with local access to the system can extract the hardcoded keys from the Veramark.Framework.dll module and decrypt the stored credentials. The recovered credentials can then be used to authenticate to the Windows host, potentially resulting in local privilege escalation depending on the privileges of the configured service account.

Title
Calero VeraSMART < 2022 R1 .NET Remoting Arbitrary File Read Leading to ViewState RCE
Summary
Calero VeraSMART versions prior to 2022 R1 expose an unauthenticated .NET Remoting HTTP service on TCP port 8001. The service publishes default ObjectURIs (including EndeavorServer.rem and RemoteFileReceiver.rem) and permits the use of SOAP and binary formatters with TypeFilterLevel set to Full. An unauthenticated remote attacker can invoke the exposed remoting endpoints to perform arbitrary file read and write operations via the WebClient class. This allows retrieval of sensitive files such as WebRoot\\web.config, which may disclose IIS machineKey validation and decryption keys. An attacker can use these keys to generate a malicious ASP.NET ViewState payload and achieve remote code execution within the IIS application context. Additionally, supplying a UNC path can trigger outbound SMB authentication from the service account, potentially exposing NTLMv2 hashes for relay or offline cracking.

Title
Calero VeraSMART < 2022 R1 Static IIS Machine Keys Enable ViewState RCE
Summary
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.
