Description
Inbit Messenger versions 4.6.0 to 4.9.0 contain a remote stack-based buffer overflow vulnerability that allows unauthenticated attackers to execute arbitrary code by sending malformed network packets. Attackers can craft a specially designed payload targeting the messenger's network handler to overwrite the Structured Exception Handler (SEH) and execute shellcode on vulnerable Windows systems.
