Advantech DiagAnywhere SET_CURR_DIR Stack-based Buffer Overflow Remote Code Execution Vulnerability

This vulnerability allows remote attackers to execute arbitrary code on affected installations of Advantech DiagAnywhere. Authentication is not required to exploit this vulnerability. The specific flaw exists within the handling of SET_CURR_DIR messages. The issue results from the lack of proper validation of the length of user-supplied data prior to copying it to a fixed-length stack-based buffer. An attacker can leverage this vulnerability to execute code in the context of the server process.
