The vulnerability lies within the \u003ccode\u003estrcpy\u003c/code\u003e function in the \u003ccode\u003e/goform/formUser\u003c/code\u003e file. A remote attacker can exploit this vulnerability by sending a crafted request that causes a buffer overflow, potentially leading to arbitrary code execution. Public exploits are available, increasing the risk of widespread exploitation.
