CVE-2019-25603

TuneClone 2.20 contains a structured exception handler (SEH) buffer overflow vulnerability that allows local attackers to execute arbitrary code by supplying a malicious license code string. Attackers can craft a payload with a controlled buffer, NSEH jump instruction, and SEH handler address pointing to a ROP gadget, then paste it into the license code field to trigger code execution and establish a bind shell.
