Unauthenticated command execution via AjaxPro deserialization
Published Jan 15, 2026 · Updated Jan 15, 2026
Deserialization in Chanjet Information Technology T+ 16.x and earlier allows remote attackers to execute commands through an AjaxPro request. GetStoreWarehouseByStore accepts a malicious JSON body and deserializes attacker-selected .NET types, enabling calls such as System.Diagnostics.Process.Start. No authentication or user interaction is required; commands run with the T+ application service account's privileges.
