TiEmu 2.08 and prior contains a stack-based buffer overflow vulnerability that allows attackers to execute arbitrary code by exploiting inadequate boundary checks on user-supplied input.
Does this matter?
High impact if exploited, but EPSS currently rates exploitation as unlikely (0.80%). Schedule it in the normal patch cycle and watch for a rise in EPSS or a public exploit.
Description
TiEmu 2.08 and prior contains a stack-based buffer overflow vulnerability that allows attackers to execute arbitrary code by exploiting inadequate boundary checks on user-supplied input. Attackers can trigger the overflow through command-line arguments passed to the application, leveraging ROP gadgets to bypass protections and execute shellcode in the application context.
