What is CVE-2023-7334?

The Changjetong T+ application exhibits a deserialization vulnerability in its AjaxPro endpoint, allowing remote attackers to send specially crafted requests. By exploiting the deserialization of attacker-controlled .NET types, an adversary can invoke arbitrary methods, such as System.Diagnostics.Process.Start, leading to the execution of arbitrary commands within the context of the T+ application service account. This weakness was identified by the Shadowserver Foundation on August 19, 2023, raising concerns about the security implications for users of this software.

Affected Version(s)
