PatchTheCVECVE-2023-7334: Changjetong T+ versions up to and including 16.x contain a .NET deserialization vulnerability in an AjaxPro en
CVE-2023-7334 is a critical-severity flaw (CVSS 9.8) affecting t\+. Below: why it ranks where it does, which versions are affected, what to do, and the exact commands.
Changjetong T+ versions up to and including 16.x contain a .NET deserialization vulnerability in an AjaxPro endpoint that can lead to remote code execution. A remote attacker can send a crafted request to /tplus/ajaxpro/Ufida.T.CodeBehind._PriorityLevel,App_Code.ashx?method=GetStoreWarehouseByStore with a malicious JSON body that leverages deserialization of attacker-controlled .NET types to invoke arbitrary methods such as System.Diagnostics.Pro
Why this priority
- Critical severity
- Public exploit reference
- CISA SSVC: automatable with total technical impact
- Remotely exploitable, no login, no user action
A fixed release or distro patch exists.
